Cladistic analysis of the family cryphaeaeae (bryophyta) with emphasis on cryphaea: a study based on a comprehensive morphological dataset
Provedor de dados: 66
Autores: Flores,Jorge R; Catalano,Santiago A; Suárez,Guillermo M.
The first comprehensive phylogenetic analysis of the Cryphaeaceae (Bryophyta), a pleurocarpic moss family, is conducted on the basis of morphological characters. The data set comprised 73 characters: 10 continuous and 63 discrete. Taxon sampling involved nine genera and 46 species of Cryphaeaceae, 32 species belonging to Cryphaea. Outgroup sampling included 23 species from 21 genera and 13 families of pleurocarpous mosses. The phylogenetic analyses were conducted using parsimony as the optimality criterion following an implied weighting approach. The results did not support the monophyly of Cryphaeaceae as it excluded Dendroalsia abietina from the family. The clade composed of the remaining genera (clade A) was diagnosed by a short seta (0.26-0.30 mm),...

Phylogenetic relationships in the Drosophila fasciola species subgroup (Diptera, Drosophilidae) inferred from partial sequences of the mitochondrial cytochrome oxidase subunit I (COI) gene
Provedor de dados: 74
Autores: Silva-Bernardi,Erica C.C.; Morales,Adriana C.; Sene,Fabio M.; Manfrin,Maura H.
The repleta group is one of the largest and most complex species groups in the genus Drosophila, representing an important biological model for the elaboration of evolutionary and biogeographical hypotheses on the American Continent. It is divided into six subgroups, of which the fasciola subgroup is the only one with most of its species found in the humid forests of Central and South America. With the aim of understanding the origin and evolution of the fasciola subgroup, and consequently adding information about the repleta group, we analyzed partial sequences of the mitochondrial cytochrome oxidase subunit I (COI) gene of nine Drosophila species (D. carolinae, D. coroica, D. ellisoni, D. fascioloides, D. ivai, D. moju, D. onca, D. rosinae and D. senei)....

Cytotaxonomy of Parodon nasus and Parodon tortuosus (Pisces, Characiformes): A case of synonymy confirmed by cytogenetic analyses
Provedor de dados: 74
Autores: Bellafronte,Elisangela; Margarido,Vladimir Pavan; Moreira-Filho,Orlando.
Morphological and cytogenetical studies were carried out on the freshwater fish Parodon nasus and Parodon tortuosus in order to evaluate a putative synonymy. The diploid chromosome number observed in both species was 2n = 54 (48M/SM and 6ST) with no differences between the sexes. Despite slight differences in the pattern of heterochromatin distribution and the number of cusps in symphysean teeth, the location of nucleolar organizer regions (NORs) and 5S rRNA genes (both species-specific features) were similar in both species. The remarkable similarity observed between these allopatric species supports recent taxonomical reviews indicating that P. tortuosus is a synonym for P. nasus.

The enigmatic monotypic crab plover Dromas ardeola is closely related to pratincoles and coursers (Aves, Charadriiformes, Glareolidae)
Provedor de dados: 74
Autores: Pereira,Sergio L.; Baker,Allan J.
The phylogenetic placement of the monotypic crab plover Dromas ardeola (Aves, Charadriiformes) remains controversial. Phylogenetic analysis of anatomical and behavioral traits using phenetic and cladistic methods of tree inference have resulted in conflicting tree topologies, suggesting a close association of Dromas to members of different suborders and lineages within Charadriiformes. Here, we revisited the issue by applying Bayesian and parsimony methods of tree inference to 2,012 anatomical and 5,183 molecular characters to a set of 22 shorebird genera (including Turnix). Our results suggest that Bayesian analysis of anatomical characters does not resolve the phylogenetic relationship of shorebirds with strong statistical support. In contrast, Bayesian...

Distribution and morphometrics of Natalus stramineus from South America (Chiroptera, Natalidae)
Provedor de dados: 76
Autores: Taddei,Valdir Antonio; Uieda,Wilson.
Morphometric and distributional data and some observations on the biology of Natalus stramineus Gray, 1838 collected in eastern Bolivia and in northern, northeastern, central, and southeastern Brazil are presented. All new records, combined with the records of the species from Paraguay and Mato Grosso, significantly change the known distribution of N. stramineus in South America. The specimens from northeastern Brazil (Rio Grande do Norte, Ceará, Bahia) are smaller than those found in the northern (Pará), eastern (Espírito Santo, São Paulo) and central regions of the country (Distrito Federal, Goiás, Mato Grosso do Sul). Natalus stramineus specimens from the three latter regions are about the same size, but are larger than those from Santa Cruz, Bolivia....

Autores: Di Iorio,Osvaldo R.
Revision of 973 specimens of Heterachthes flavicornis (Thomson, 1865), mostly emerged from a same individual of different host plant species, shows that this species has a high phenotypical variation in the color of elytra, antennae and legs. This variability is not related to the geographical distribution or to the host plants. Heterachthes flavicornis sexsignatus (Thomson,1865), and Heterachthes flavicornis bonariensis (Thomson,1865) are considered into the synonymy of Heterachthes flavicornis (Thomson, 1865).

On Munduruku, a new Theraphosid genus from Oriental Amazonia (Araneae, Mygalomorphae)
Provedor de dados: 76
Autores: Miglio,Laura T.; Bonaldo,Alexandre B.; Pérez-Miles,Fernando.
Munduruku gen. nov. is proposed for the type species Munduruku bicoloratum sp. nov., from Juruti and Santarém, Pará, Brazil. The main diagnostic character of Munduruku gen. nov. is the presence of a subapical, lanceolate keel on the male palpal bulb, which is unique among the basal taxa of Theraphosinae with type III-IV urticating setae. The female spermathecae consist of two spheroid receptacles with funnel-shaped necks, each of which bears a sclerotized area. In both sexes, the abdomen is remarkably patterned, an uncommon feature in adults of New World theraphosids. Both the bulbus lanceolate keel and the abdominal color pattern are hypothesized as synapomorphies of the genus.

Some considerations for analyzing biodiversity using integrative metagenomics and gene networks
Provedor de dados: 5
Autores: Bittner, Lucie; Halary, Sebastien; Payri, Claude; Cruaud, Corinne; De Reviers, Bruno; Lopez, Philippe; Bapteste, Eric.
Background:  Improving knowledge of biodiversity will benefit conservation biology, enhance bioremediation studies, and could lead to new medical treatments. However there is no standard approach to estimate and to compare the diversity of different environments, or to study its past, and possibly, future evolution. Presentation of the hypothesis:  We argue that there are two conditions for significant progress in the identification and quantification of biodiversity. First, integrative metagenomic studies - aiming at the simultaneous examination (or even better at the integration) of observations about the elements, functions and evolutionary processes captured by the massive sequencing of multiple markers - should be preferred over DNA barcoding projects...

Systematics and phylogeny of the caryophyllidia-bearing dorids (Mollusca, Nudibranchia), with descriptions of a new genus and four new species from Indo-Pacific deep waters
Provedor de dados: 5
Autores: Valdes, A; Gosliner, Tm.
The phylogenetic relationships of the caryophyllidia-bearing dorids are studied, based on the examination of the type species of all the genera previously described. The phylogenetic hypothesis supports that the caryophyllidia-bearing dorids area monophyletic group and the sister group of the clade formed by Asteronotus Ehrenberg, 1831 and Halgerda Bergh, 1880. Several genera previously considered as valid or regarded as uncertain are here synonymized: Peronodoris Bergh, 1904, Trippa Bergh, 1877, Phlegmodoris Bergh, 1878, Petelodoris Bergh, 1881, Kentrodoris Bergh, 1876, Audura Bergh, 1878, Centrodoris P.

The scleractinian family Lobophylliidae is undergoing a major taxonomic revision thanks to the combination of molecular and morphological data. In this study, we investigate the evolutionary relationships and the macro- and micromorphology of six nominal coral species belonging to two of the nine molecular clades of the Lobophylliidae, clades A and B, and of Symphyllia wilsoni, a lobophylliid species analyzed from a molecular point of view for the first time. Sequence data from mitochondrial DNA (COI and the intergenic spacer between COI and l-rRNA), and nuclear DNA (histone H3 and ITS region) are used to generate robust molecular phylogenies and a median-joining haplotype network. Molecular results are strongly in agreement with detailed observations of...

A new deep-sea genus of nannastacidae (Crustacea, cumacea) from the lucky strike hydrothermal vent field (Azores triple junction, mid-atlantic ridge)
Provedor de dados: 5
Autores: Corbera, J; Segonzac, Michel; Cunha, M.
A new cumacean genus and species, Thalycrocuma sarradini gen. et sp. nov., belonging to the family Nannastacidae is described from several sites of the Lucky Strike hydrothermal vent field (Mid-Atlantic Ridge, 37N, 1700 m depth). The new genus differs from others in the family by males lacking exopods on the pereopods 3 and 4 and having an antenna with a five-articulate peduncle and a short flagellum. This is the first cumacean species that could be considered, at the moment, as endemic from hydrothermal vent areas. Data on the accompanying fauna including other cumacean species (Cyclaspis longicaudata, Bathycuma brevirostre, Procampylaspis sp. and Makrokylindrus sp.) and some ecological remarks are included.

Surface Microornamentation of Demosponge Sterraster Spicules, Phylogenetic and Paleontological Implications
Provedor de dados: 5
Autores: Cárdenas, Paco.
Siliceous spicules in demosponges exist in a variety of shapes, some of which look like minute spheres of glass. They are called “sterrasters” when they belong to the Geodiidae family (Tetractinellida order) and “selenasters” when they belong to the Placospongiidae family (Clionaida order). Today, the Geodiidae represent a highly diverse sponge family with more than 340 species, occurring in shallow to deep waters worldwide, except for the Antarctic. The molecular phylogeny of Geodiidae is currently difficult to interpret because we are lacking morphological characters to support most of its clades. To fill this knowledge gap, the surface microornamentations of sterrasters were compared in different genera. Observations with scanning electron microscopy...

Autores: Luis Carballo, Jose; Bautista-guerrero, Eric; Cardenas, Paco; Cruz-barraza, Jose Antonio; Aguilar-camacho, Jose Maria.
The Thoosidae (Porifera, Demospongiae, Tetractinellida) currently includes the genera Thoosa, Alectona, and Delectona. To this date, molecular data are only available for Alectona. In this study, the phylogenetic affinities of the genera Thoosa and Alectona have been investigated with the species T. mismalolli, T. calpulli, and T. purpurea from the Mexican Pacific using morphology and three molecular loci: the mitochondrial cytochrome oxidase subunit 1 (CO1 mtDNA), 28S rRNA (fragment D2), and 18S rRNA. Morphology and embryology showed that these genera are quite different from the rest of the tetractinellids because larvae of Alectona and Thoosa have unique features in sponges, such as the presence of monaxonic discs in Thoosa and tetraxonic discs in...

Taxonomy and phylogenetic relationships of the coral genera Australomussa and Parascolymia (Scleractinia, Lobophylliidae)
Provedor de dados: 5
Autores: Arrigoni, Roberto; Richards, Zoe T.; Chen, Chaolun Allen; Baird, Andrew H.; Benzoni, Francesca.
Novel micromorphological characters in combination with molecular studies have led to an extensive revision of the taxonomy and systematics of scleractinian corals. In the present work, we investigate the macro- and micromorphology and the phylogenetic position of the genera Australomussa and Parascolymia, two monotypic genera ascribed to the family Lobophylliidae. The molecular phylogeny of both genera was addressed using three markers, the partial mitochondrial COI gene and the nuclear histone H3 and the ribosomal ITS region. Based on molecular data, Australomussa and Parascolymia belong to the Lobophylliidae and they cluster together with the genera Lobophyllia and Symphyllia within the same clade. While A. rowleyensis and P. vitiensis are closely...

Sanitation with sponge and plunger: western Atlantic slit-wormsnails (Mollusca : Caenogastropoda : Siliquariidae)
Provedor de dados: 5
Autores: Bieler, R.
Siliquariid Tenagodus (synonym: Siliquaria) snails are obligatory sponge commensals, with uncoiling and laterally slitted shells embedded inside Demospongiae hosts, and shell apertures facing the outside allowing for respiratory and gill-filter-feeding activities. Live-collected animals observed in situ within hosts provide the first detailed functional morphological study of the group, and form the basis for systematic revision of the western Atlantic members of type genus Tenagodus (Siliquariidae, synonym: Tenagodidae). Three species are recognized. Overall anatomical features of wide-ranging Atlantic T. modestus (Dall, 1881) and T. squamatus (de Blainville, 1827) [ = T. anguillae Morch, 18611 are similar to those previously described for New Zealand...

(Crustacea, Copepoda: Harpacticoida: Tisbidae) is described from the Eiffel Tower edifice located in the Lucky Strike vent field (37 degrees N) (Mid-Atlantic Ridge MAR, 1698 m). The samples were collected in colonization experiments (SMAC arrays) that were deployed in 1997 during the MARVEL cruise and recovered in 1998 during the PICO cruise. Other specimens were collected during the MoMARETO cruise during which a physico-chemical characterization of copepod microhabitats was done. The new species belongs to the T. gracilis group based on similarities of the spine-like inner seta on the proximal endopodal segment of the male second swimming leg, which is terminally bifurcate. Re-examination of the closest relative and...

Relationships of the haematophagous marine snail Colubraria (Rachiglossa: Colubrariidae), within the neogastropod phylogenetic framework
Provedor de dados: 5
Autores: Oliverio, Marco; Modica, Maria Vittoria.
The gastropod genus Colubraria includes marine shallow-water species from tropical, subtropical, and temperate rocky coral environments. At least six species are known to feed on fish blood. Although there is general consensus in placing Colubraria in the Neogastropoda, the actual relationships and the systematic position of Colubraria and related genera are unknown. This is partly the consequence of the lack of a clear phylogenetic framework for the Neogastropoda. This study attempts to propose a phylogenetic framework for the Neogastropoda, by testing: (1) a preliminary phylogenetic arrangement for a large number of recognized neogastropod families; (2) the position of Colubraria within the neogastropods; and (3) the relationships of Colubraria within...

VENEZUELAN ARACHNIDES: TWO NEW SPECIES OF THE Tityus GENUS (SCORPIONIDA: BUTHIDAE) IN THE STATE OF LARA
Provedor de dados: 79
Autores: GONZALES-SPONGA,M. A.
Two new scorpion species of the Buthidae family, Tityus ivic-nancor and Tityus sanarensis, are described in this paper. Both species belong to the "androcottoides" group and live from 1300 to 1400 m. above sea level near the town of Sanare (69º42'17.8"W, 9º45'3.9"N) in the southern part of the state of Lara in Venezuela. The number of Tityus species already known in Venezuela increases to 28 with the inclusion of these two new species. This paper includes a descriptive diagnosis and also a differential diagnosis of the species of Tityus that are geographically related to T. ivic-nancor and T. sanarensis. Drawings of the significant morphological characteristics of male and female specimens and a morphometric table are also included.

Evaluación de los caracteres diagnósticos de Oxymycterus josei Hoffmann, Lessa y Smith, 2002 (Rodentia: Cricetidae) con comentarios sobre la diferenciación de las especies uruguayas del género
Provedor de dados: 81
Autores: García-Olaso,Felipe.
Actualmente se reconocen dos especies del género Oxymycterus en Uruguay: O. nasutus y O. josei. Estas especies parecen ser un caso particular dentro del género, ya que son simpátridas, genéticamente diferenciadas pero morfológicamente muy similares. Principalmente, dos caracteres diagnósticos fueron descritos para distinguirlas. Este trabajo evalúa la consistencia de esos dos caracteres craneodentarios para diferenciar las especies. Los resultados descartan los pliegues dentarios, pero corroboran al ancho de placa zigomática, como caracteres diagnósticos de O. josei. El actual conocimiento genético, morfológico y geográfico del género en la región sugiere que hay interrogantes históricas que permanecen por ser resueltas.

Rediscovery and redescription of Marmosops handleyi (Pine, 1981) (Didelphimorphia: Didelphidae), the least known andean slender mouse opossum
Provedor de dados: 81
Autores: Díaz-N.,Juan F.; Gómez-Laverde,Marcela; Sánchez-Giraldo,Camilo.
Marmosops handleyi was briefly described in 1981 based on two specimens collected in 1950 in the northern Andes of Colombia. Until now there have been no additional reported records for this species, and knowledge about its taxonomy, ecology, natural history and evolutionary relationships is deficient. Aiming to assess its current distribution, we searched for this species at four localities in the northern part of the Colombian Cordillera Central, where we collected the new material on which this report is based. Morphological comparisons with a sympatric congeneric species herein identified as M. caucae, revealed new external and craniodental characters that we use to redescribe M. handleyi. Our phylogenetic analysis groups M. handleyi as the sister...

A distinctive new cloud-forest rodent (Hystricognathi: Echimyidae) from the Manu Biosphere Reserve, Peru
Provedor de dados: 81
Autores: Patterson,Bruce D.; Velazco,Paul M.
Recent surveys in Peru 's Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of "brush-tailed tree rats" previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. While the inclusion of the new taxon does not resolve the "star phylogeny" which underlies the echimyid radiation, it identifies the Andes as a possible theatre for the evolution of some soft-haired members of the group. The new species is described and a revised diagnosis of the...

Current perspectives on the evolution of birds
Provedor de dados: 16
Autores: Ericson, P.G.P.
The paper summarizes the current understanding of the evolution and diversification of birds. New insights into this field have mainly come from two fundamentally different, but complementary sources of information: the many newly discovered Mesozoic bird fossils and the wealth of genetic analyses of living birds at various taxonomic levels. The birds have evolved from theropod dinosaurs from which they can be defined by but a few morphological characters. The early evolutionary history of the group is characterized by the extinctions of many major clades by the end of the Cretaceous, and by several periods of rapid radiations and speciation. Recent years have seen a growing consensus about the higher- level relationships among living birds, at least as...

Morphological variation and taxonomic revision of five south-eastern subspecies of Lesser Whitethroat Sylvia curruca (L.) (Aves: Sylviidae)
Provedor de dados: 16
Autores: Loskot, V.M.
Individual, sex, age, seasonal and geographic variation of size and plumage coloration of Lesser Whitethroat Sylvia curruca (Linnaeus, 1758) was studied on more than 1100 bird skins from all parts of its breeding range. The results of analysis of birds from the south-eastern part of the breeding range of the species support the validity of five light-coloured subspecies: halimodendri Sushkin, 1904, telengitica Sushkin, 1925, snigirewskii Stachanow, 1929, minula Hume, 1873, and margelanica Stolzmann, 1897. Their diagnoses and ranges are refined and supplemented. Numerous phenotypically intermediate birds from intergradation zones between the subspecies show that these five together with the two northern darkcoloured forms S. c. curruca and S. c. blythi...

A review of the Ustilago-Sporisorium-Macalpinomyces complex
Provedor de dados: 16
Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Vánky, K.; Scharaschkin, T.
The fungal genera Ustilago, Sporisorium and Macalpinomyces represent an unresolved complex. Taxa within the complex often possess characters that occur in more than one genus, creating uncertainty for species placement. Previous studies have indicated that the genera cannot be separated based on morphology alone. Here we chronologically review the history of the Ustilago-Sporisorium-Macalpinomyces complex, argue for its resolution and suggest methods to accomplish a stable taxonomy. A combined molecular and morphological approach is required to identify synapomorphic characters that underpin a new classification. Ustilago, Sporisorium and Macalpinomyces require explicit re-description and new genera, based on monophyletic groups, are needed to accommodate...

Taxonomy and evolutionary history of the neotropical fern genus Salpichlaena (Blechnaceae)
Provedor de dados: 16
Autores: Cárdenas, G.G.; Lehtonen, S.; Tuomisto, H.
Salpichlaena is a distinctive fern genus characterised by 2-pinnate climbing fronds with indeterminate growth. The number of species in the genus has been a matter of debate. Taxonomic studies are made difficult by within-frond variability in pinna morphology and size, and by herbarium material being incomplete. We systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena and 11 outgroup specimens. DNA sequences included plastid genes (rbcL, rpoC1 and rps4), intergenic spacers (rps4-trnS, trnHpsbA and trnG-trnR) and a nuclear gene (pgiC). Phylogenetic analyses based on the plastid markers divided the samples into six major clades. We recognise the three deepest clades as distinct species (S. hookeriana, S....

Phylogenetic analyses of DNA sequences from nuclear ribosomal and protein-coding loci support the placement of several perithecial ascomycetes and dematiaceous hyphomycetes from freshwater and terrestrial environments in two monophyletic clades closely related to the Savoryellales. One clade formed by five species of Conioscypha and a second clade containing several genera of uncertain taxonomic status centred on Pleurothecium, represent two distinct taxonomic groups at the ordinal systematic rank. They are proposed as new orders, the Conioscyphales and Pleurotheciales. Several taxonomic novelties are introduced in the Pleurotheciales, i.e. two new genera (Adelosphaeria and Melanotrigonum), three novel species (A. catenata, M. ovale, Phaeoisaria...

Autores: Damm, U.; Fourie, P.H.; Crous, P.W.
Species of the genus Coniochaeta (anamorph: Lecythophora) are known as pathogens of woody hosts, but can also cause opportunistic human infections. Several fungi with conidial stages resembling Lecythophora were isolated from necrotic wood samples of Prunus trees in South Africa. In order to reveal their phylogenetic relationships, these fungi were studied on a morphological and molecular (5.8S nrDNA, ITS-1, ITS-2, GAPDH, EF-1α, 28S nrDNA, 18S nrDNA) basis. Some of the isolates were identified as Coniochaeta (Sordariomycetes), including C. velutina and two new species, C. africana and C. prunicola. The majority of the isolates, however, formed pycnidial or pseudopycnidial synanamorphs and were not closely related to Coniochaeta. According to their 28S...

The leaf anatomical diversity of the genera Baccaurea Lour. (43 species), Distichirhops Haegens (3 species) and Nothobaccaurea Haegens (2 species) (Euphorbiaceae) is described. Two species of Aporosa and three species of Maesobotrya were examined for comparison. The following characters are important for the delimitation of species: hair types, the position of the glandular areas on the leaf margin, the hairiness and size of the glandular areas, the number of epidermal layers, the presence of (mucilage) idioblasts in the epidermis, the presence of palisade parenchyma above the vascular bundles, and the birefringence of the spongy parenchyma cell walls. However, leaf anatomy did not yield characters for distinction between the five genera studied. Phenetic...

Autores: Bianucci, G.; Landini, W.
An incomplete odontocete (Mammalia, Cetacea) skull from Middle Miocene Miste Bed (near Winterswijk in the eastern part of The Netherlands) is described as Vanbreenia trigonia, a new genus and species. The skull exhibits a short rostrum with only two maxillary teeth for each toothrow and with narrow and toothless apical portion exclusively formed by the premaxilla. Considering this last character, the specimen could belong to the Eurhinodelphinidae even if a certain attribution is not possible because of the incompleteness of the specimen. Vanbreenia n. gen. could represent a specialized adaptation to bottom suction feeding among the eurhinodelphinids.

A re-appraisal of Harknessia (Diaporthales), and the introduction of Harknessiaceae fam. nov.
Provedor de dados: 16
Autores: Crous, P.W.; Summerell, B.A.; Shivas, R.G.; Carnegie, A.J.; Groenewald, J.Z.
Harknessiaceae is introduced as a new family in the ascomycete order Diaporthales to accommodate species of Harknessia with their Wuestneia-like teleomorphs. The family is distinguished by having pycnidial conidiomata with brown, furfuraceous margins, brown conidia with hyaline, tube-like basal appendages, longitudinal striations, and rhexolytic secession. Six species occurring on Eucalyptus are newly introduced, namely H. australiensis, H. ellipsoidea, H. pseudohawaiiensis, and H. ravenstreetina from Australia, H. kleinzeeina from South Africa, and H. viterboensis from Italy. Epitypes are designated for H. spermatoidea and H. weresubiae, both also occurring on Eucalyptus. Members of Harknessia are commonly associated with leaf spots, but also occur as...

New combinations for two coronate polyp species (Atorellidae and Nausithoidae, Coronatae, Scyphozoa, Cnidaria)
Provedor de dados: 16
Autores: Morandini, A.C.; Jarms, G.
Within the order Coronatae, six valid species remain known only by their polyp stage. The inability to relate them to any medusae genera of the group is a problem that remains to be solved in the order. With the examination of type specimens, we reassign the species Stephanoscyphistoma sibogae and S. striatus to the genera Atorella and Nausithoe respectively.

Sertularia vervoorti (Hydrozoa: Sertulariidae), an undescribed species of hydroid from Brazil
Provedor de dados: 16
Autores: Migotto, A.E.; Calder, D.R.
An account is given of Sertularia vervoorti spec. nov., a small leptothecate species collected in coastal waters of southeastern Brazil. Specimens were found on brown algae, collected at depths of 15-20 m on the inner continental shelf off Espírito Santo state. This hydroid resembles Sertularia tumida Allman, 1877, S. linealis Warren, 1908, and S. longa Millard, 1958, but differs from these and other species of the genus in having an unusual bulge around the hydrothecal wall just distal to its insertion with the hydrocaulus. The colony form of S. vervoorti is more compact than in these species, and gonothecae are annulated rather than smooth as in S. linealis and S. longa.

The identity of Isocrassina, Laevastarte and Ashtarotha (Mollusca, Bivalvia, Astartidae) and their representatives from beaches and estuaries in The Netherlands and Pliocene strata in Belgium
Provedor de dados: 16
Autores: Pouwer, R.
The identity of the subgenera Isocrassina Chavan, 1950, Laevastarte Hinsch, 1952, and Ashtarotha Dall, 1903, of the genus Astarte Sowerby, 1816 in the family Astartidae (Mollusca, Bivalvia) is discussed. Isocrassina has been widely used for Pliocene species in the North Sea Basin. Here it is demonstrated, that this is based on a redefinition of this subgenus, which excludes its type-species. As the North Sea species differ considerably from the type-species of Isocrassina in aspects of ornament and details of the hinge, it is concluded that they should be placed in the genus Laevastarte. A slightly modified definition of Isocrassina and Laevastarte is given and both are raised to genus level. The morphological basis for Ashtarotha is quite weak and it is...

Multi-locus phylogeny and taxonomy of Exserohilum
Provedor de dados: 16
Autores: Hernández-Restrepo, M.; Madrid, H.; Tan, Y.P.; Cunha, K.C. da; Gené, J.; Guarro, J.; Crous, P.W.
Exserohilum includes a number of plant pathogenic, saprobic and clinically relevant fungi. Some of these species are of great importance in human activities, but the genus has never been revised in a phylogenetic framework. In this study, we revise Exserohilum based on available ex-type cultures from worldwide collections, observation of the holotypes and/or protologues, and additional isolates from diverse substrates and geographical origins. Based on nine nuclear loci, i.e., ITS, LSU, act, tub2, cam, gapdh, his, tef1 and rpb2, as well as phenotypic data, the genus and species boundaries are assessed for Exserohilum. Three species, i.e., E. novae-zelandiae, E. paspali and E. sorghicola, are excluded from the genus and reallocated in Sporidesmiella and...

A crinoid crown from the Wenlock (Silurian) of Coalbrookdale, Shropshire, England
Provedor de dados: 16
Autores: Donovan, S.K.; Lewis, D.N.
The specific diversity of fossil crinoids from the Much Wenlock Limestone Formation at Dudley, Worcestershire, and in Shropshire differ by an order of magnitude. The latter are relatively depauperate and include only about six nominal species. Over 165 years ago, a specimen from Coalbrookdale, Shropshire, was identified as Cyathocrinites tuberculatus Miller (= the taxocrinid flexible Protaxocrinus tuberculatus (Miller)). This specimen, although indifferently preserved, is distinct from other Silurian crinoids of the British Isles and is described herein as a monobathrid camerate, Macrostylocrinus? jefferiesi sp. nov. This species has a moderately large, conical dorsal cup with at least 20 arms, broad primibrachials, a granular surface sculpture and no ray...

Autores: Duarte, A.P.M.; Attili-Angelis, D.; Baron, N.C.; Groenewald, J.Z.; Crous, P.W.; Pagnocca, F.C.
Isolates of Teratosphaeriaceae have frequently been found in the integument of attine ants, proving to be common and diverse in this microenvironment. The LSU phylogeny of the ant-isolated strains studied revealed  that they cluster in two main lineages. The first was associated with the genus Xenopenidiella whereas the other represented two ant-isolated lineages sister to the taxa Penidiella aggregata and P. drakensbergensis, which are allocated to the new genus Penidiellomyces. The genus Penidiella is limited to the lineage containing P. columbiana, which is not congeneric with Penidiellomyces or Penidiellopsis, nor with Simplicidiella, a novel genus introduced here to accommodate a strain isolated from ants. For species level analysis, the final 26...

Why everlastings don’t last
Provedor de dados: 16
Autores: Crous, P.W.; Groenewald, J.Z.
The Cape Floral Region represents one of the world’s biodiversity hot spots, with a high level of plant, animal and insect endemism. The fungi occurring in this region, however, remain poorly studied. It is widely postulated that each plant species should harbour at least five to six unique fungal species, a number that we regard to be a huge underestimate. To test this hypothesis, we decided to study a single senescent flower of Phaenocoma prolifera (‘everlasting’; Asteraceae) collected in South Africa, and posed the question as to how many different species of fungi could be isolated and cultivated from 10 leaf bracts. Using a damp chamber technique, numerous microfungi could be induced to sporulate, enabling most of them to be successfully isolated on...

Morphological and molecular characterisation of a new anamorphic genus Cheirosporium, from freshwater in China
Provedor de dados: 16
Autores: Cai, L.; Guo, X.Y.; Hyde, K.D.
Cheirosporium gen. nov. is characterised by the production of sporodochial conidiomata, semi-macronematous to macronematous conidiophores that possess several distinct sterile branches, and cheiroid, smooth-walled conidia with rhexolytic secession. The 28S rDNA and ITS rDNA operon of this taxon were amplified and sequenced. A BLAST search revealed low homology between Cheirosporium triseriale and existing sequences in public databases, supporting the hypothesis that the species is new to science. Phylogenetic analysis showed that C. triseriale groups with Dictyosporium and allied species, and nests within the Pleosporales (Dothideomycetes, Ascomycota). heirosporium is morphologically distinct from the cheirosporous genera Cheiromyces, Cheiromycina,...

The Colletotrichum gigasporum species complex
Provedor de dados: 16
Autores: Liu, F.; Cai, L.; Crous, P.W.; Damm, U.
In a preliminary analysis, 21 Colletotrichum strains with large conidia preserved in the CBS culture collection clustered with a recently described species, C. gigasporum, forming a clade distinct from other currently known Colletotrichum species complexes. Multi-locus phylogenetic analyses (ITS, ACT, TUB2, CHS-1, GAPDH) as well as each of the single-locus analyses resolved seven distinct species, one of them being C. gigasporum. Colletotrichum gigasporum and its close allies thus constitute a previously unknown species complex with shared morphological features. Five of the seven species accepted in the C. gigasporum species complex are described here as novel species, namely C. arxii, C. magnisporum, C. pseudomajus, C. radicis and C. vietnamense. A...

Comparative wood anatomy of the blueberry tribe (Vaccinieae, Ericaceae s.l.)
Provedor de dados: 16
Autores: Lens, F.; Kron, K.A.; Luteyn, J.L.; Smets, E.; Jansen, S.
Wood samples of 111 Vaccinieae specimens (Vaccinioideae, Ericaceae s.l.) representing 98 species and 26 genera are investigated with light microscopy and scanning electron microscopy. The wood structure of Vaccinieae delivers taxonomically important characters that can be used to define some subclades within the tribe. The wood of the large polyphyletic genus Vaccinium strongly resembles non-vaccinioid members of the family, which are characterized by bordered vessel-ray pits and relatively narrow (2- to 4-seriate) and low multiseriate rays (often less than 1000 mm) with exclusively or mainly procumbent body ray cells. The East Malesian clade, Meso-American/Caribbean clade, and the Andean clade show a combination of wood anatomical features that is lacking...

A note on three species of Taractrocera Butler (Lepidoptera: Hesperiidae)
Provedor de dados: 16
Autores: Jong, R. de.
Three similar looking species of Taractrocera, generally known as ziclea Plötz, archias Felder and alinea Plotz, are re-examined and existing confusion is clarified. As a consequence, the correct name for the first species is shown to be T. luzonensis (Staudinger), and for the last species T. nigrolimbata (Snellen). The name Thymelicus ziclea Plötz turned out to be a junior synonym of Pamphila archias Felder. Diagnostic characters are given to separate the three species, and the geographic variation is surveyed.

Calonectria species associated with cutting rot of Eucalyptus
Provedor de dados: 16
Autores: Lombard, L.; Zhou, X.D.; Crous, P.W.; Wingfield, B.D.; Wingfield, M.J.
Decline in the productivity of Eucalyptus hybrid cutting production in the Guangdong Province of China is linked to cutting rot associated with several Calonectria spp. The aim of this study was to identify these fungi using morphological and DNA sequence comparisons. Two previously undescribed Calonectria spp., Ca. pseudoreteaudii sp. nov. and Ca. cerciana sp. nov. were identified together with Ca. pauciramosa. Calonectria pseudoreteaudii resides in the Ca. reteaudii complex and Ca. cerciana is closely related to Ca. morganii. Connected to the discovery of Ca. pseudoreteaudii, species in the Ca. reteaudii complex were re-considered and the group is shown to accommodate two cryptic species. These originate from Australia and are described as Ca....

Morphological study and taxonomical notes on Eudendriidae (Cnidaria: Hydrozoa: Athecatae/Anthomedusae)
Provedor de dados: 16
Autores: Marques, A.C.; Mergner, H.; Höinghaus, R.; Santos, C.M.D.; Vervoort, W.
The morphology of 25 species of the family Eudendriidae was studied, with special regard to their reproductive organs, using techniques of SEM and optical microscopy. Whenever possible a re-analysis of the diagnostic characters of these species was carried out. Furthermore, several synonymies were confirmed or discussed and remarks on taxonomical details are presented. A developmental (ontogenetical) series is proposed for the reproductive differentiation, and its usefulness for phylogenetic analysis is considered.

Resolving the Diaporthe species occurring on soybean in Croatia
Provedor de dados: 16
Autores: Santos, J.M.; Vrandečić, K.; Ćosić, J.; Duvnjak, T.; Phillips , A.J.L.
Diaporthe (anamorph = Phomopsis) species are plant pathogens and endophytes on a wide range of hosts including economically important crops. At least four Diaporthe taxa occur on soybean and they are responsible for serious diseases and significant yield losses. Although several studies have extensively described the culture and morphological characters of these pathogens, their taxonomy has not been fully resolved. Diaporthe and Phomopsis isolates were obtained from soybean and other plant hosts throughout Croatia. Phylogenetic relationships were determined through analyses of partial translation elongation factor 1-alpha (EF1-α) gene and ITS nrDNA sequence data. By combining morphological and molecular data, four species could be distinguished on...

Eudendrium pocaruquarum n. sp. (Hydrozoa, Eudendriidae) from the southeastern coast of Brazil, with remarks on taxonomic approaches to the family Eudendriidae
Provedor de dados: 16
Autores: Marques, Antonio C.
Eudendrium pocaruquarum, a new species of athecate hydroid referable to the family Eudendriidae, is described from the state of São Paulo, Brazil. The species is very similar to the widespread Eudendrium ramosum (Linnaeus, 1758), differing from it in the smaller size of the large microbasic euryteles. Longstanding problems in the systematics of eudendriid hydroids are noted, and the inadequacies of many early descriptions of species are discussed. The nematocysts provide a supplementary character for discrimination of species of Eudendrium, although information on the cnidome appears to have been sometimes misinterpreted in literature.

Dentaliids (Mollusca, Scaphopoda) from the type Maastrichtian, the Netherlands and Belgium
Provedor de dados: 16
Autores: Donovan, S.K.; Jagt, J.W.M.
Scaphopods remain poorly known from the type area of the Maastrichtian Stage in northeast Belgium and the southeast Netherlands. At least three species appear to be represented, but incomplete preservation (i.e., lack of shell material) hampers a detailed systematic treatment of most specimens. In museum collections, the name Dentalium nysti Binkhorst van den Binkhorst, 1861 (= D. binkhorsti Pilsbry &amp; Sharp, 1898; non D. nysti d’Orbigny, 1852) is often used rather indiscriminately for both genuine scaphopods and internal moulds of serpulid worm tubes. Here, we describe and illustrate Antalis? binkhorsti, Fissidentalium? sp. 1 and Dentaliidae sp. indet., all of Maastrichtian age, as well as a late Campanian form, Fissidentalium? sp. 2.

Comparative tadpole morphology in three species of frogs of the genus Spinomantis (Amphibia: Mantellidae)
Provedor de dados: 16
Autores: Vejarano, S.; Thomas, M.; Vences, M.
We describe the tadpoles of three species of Malagasy frogs, classified in the genus Spinomantis, based on specimens identified by DNA barcoding. The tadpole of Spinomantis aglavei is a typical Orton type IV larva. The oral disc is not emarginated laterally, but has two mid-ventral folds and a labial tooth row formula of 3(2- 3)/2(1). The tadpole of S. phantasticus is similar, the oral disc being laterally emarginated and having one medial fold; LTRF is 3/3(1). A third species, S. cf. fimbriatus is also similar to the other two species; the oral disc is not laterally emarginated but has three medial folds and LTRF is 3(2-3)/3(1). One shared character is a median fold or emargination in the lower part of the oral disc, although the shape of this fold is...

Novel fungi from an ancient niche: cercosporoid and related sexual morphs on ferns
Provedor de dados: 16
Autores: Guatimosim, E.; Schwartsburd, P.B.; Barreto, R.W.; Crous, P.W.
The fern flora of the world (Pteridophyta) has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists. Cercosporoid fungi represent a large assemblage of fungi belonging to the Mycosphaerellaceae and Teratosphaeriaceae (Ascomycota) having cercospora-like asexual morphs. They are well-known pathogens of many important crops, occurring on a wide host range. Here, the results of a taxonomic study of cercosporoid fungi collected on ferns in Brazil are presented. Specimens were obtained...

Plectosphaerella species associated with root and collar rots of horticultural crops in southern Italy
Provedor de dados: 16
Autores: Carlucci, A.; Raimondo, M.L.; Santos, J.; Phillips, A.J.L.
Plectosphaerella cucumerina, most frequently encountered in its Plectosporium state, is well known as a pathogen of several plant species causing fruit, root and collar rot, and collapse. It is considered to pose a serious threat to melon (Cucumis melo) production in Italy. In the present study, an intensive sampling of diseased cucurbits as well as tomato and bell pepper was done and the fungal pathogens present on them were isolated. Phylogenetic relationships of the isolates were determined through a study of ribosomal RNA gene sequences (ITS cluster and D1/D2 domain of the 28S rRNA gene). Combining morphological, culture and molecular data, six species were distinguished. One of these (Pa. cucumerina) is already known. Four new species are described as...

Autores: Stuppy, W.; Welzen, P.C. van; Klinratana, P.; Posa, M.C.T.
The three closely related genera Aleurites J. R. Forst. &amp; G. Forst., Reutealis Airy Shaw and Vernicia Lour., together constituting the subtribe Aleuritinae of the tribe Aleuritideae (Euphorbiaceae subfamily Crotonoideae), are revised. Originally included in Aleurites, Reutealis and Vernicia are considered generically distinct on account of differences in the indumentum, leaf base, inflorescences, number of stamens and fruit type. This distinction has also been confirmed by a recent phylogenetic analysis. Aleurites (2 species) differs from Reutealis and Vernicia by the more numerous stamens arranged in 4 rather than in 2 whorls, and the indehiscent fruits. The monotypic genus Reutealis can easily be distinguished from Aleurites and Vernicia by its...

Caddick &amp; Wilkin (Dioscoreaceae)—is described and illustrated using LM, SEM, and TEM. The main difference is in microsporogenesis, which is successive in Narthecium Huds. and simultaneous in Tacca J.R. &amp; G. Forst. and Dioscorea L. This is reflected in the tetrad configuration but not in the apertures: Narthecium and Tacca are monosulcate, while Dioscorea has two equatorial apertures. Other features of pollen development are similar in all three genera. Exine development starts at the proximal pole, and during the tetrad stage,...

Provedor de dados: 16
Autores: Diao, Y.-Z.; Zhang, C.; Liu, F.; Wang, W.-Z.; Liu, L.; Cai, L.; Liu, X.-L.
Anthracnose caused by Colletotrichum species is a serious disease of more than 30 plant genera. Several Colletotrichum species have been reported to infect chili in different countries. Although China is the largest chiliproducing country, little is known about the species that have been infecting chili locally. Therefore, we collected samples of diseased chili from 29 provinces of China, from which 1285 strains were isolated. The morphological characters of all strains were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT, CAL, CHS-1, GAPDH, TUB2, and HIS3) were performed on selected representative strains. Fifteen Colletotrichum species were identified, with C. fioriniae, C. fructicola, C. gloeosporioides, C. scovillei, and C....

Species of Leucadendron, Leucospermum and Protea (Proteaceae) are in high demand for the international floriculture market due to their brightly coloured and textured flowers or bracts. Fungal pathogens, however, create a serious problem in cultivating flawless blooms. The aim of the present study was to characterise several of these pathogens using morphology, culture characteristics, and DNA sequence data of the rRNA-ITS and LSU genes. In some cases additional genes such as TEF 1-α and CHS were also sequenced. Based on the results of this study, several novel species and genera are described. Brunneosphaerella leaf blight is shown to be caused by three species, namely B. jonkershoekensis on Protea repens, B. nitidae sp. nov. on Protea nitida and B....

Benthic shallow-water hydroids (Cnidaria, Hydrozoa) of the coast of São Sebastião, Brazil, including a checklist of Brazilian hydroids
Provedor de dados: 16
Autores: Migotto, A.E.
The paper presents the results of a general survey of the hydroid fauna of the coastal region of the São Sebastião Channel, São Paulo State, Brazil. Intensive collecting in the intertidal and infralittoral zones, from 1984 to 1992, led to the discovery of many species, some of which are small and inconspicuous. Out of 59 species of hydroids (17 athecate and 42 thecate) described and illustrated, three are new records for the Atlantic Ocean, six for the western South Atlantic, and 21 for the Brazilian coast. The medusa stage of Asyncoryne ryniensis and the cnidome of 24 species are described for the first time. The paper also contains a synopsis of the hydroids recorded from the Brazilian coast, the list now including 107 species. Pseudostenotele...

Lower Miocene echinoderms of Jamaica, West Indies
Provedor de dados: 16
Autores: Donovan, S.K.; Portell, R.W.; Veltkamp, C.J.
Despite being diverse globally, Miocene echinoids are poorly known from Jamaica. Moderately diverse echinoids and other echinoderms have been identified mainly from fragmentary specimens collected from chalks and mass-flow deposits of the Lower Miocene Montpelier Formation, White Limestone Group, near Duncans, parish of Trelawny. This locality has yielded the most diverse association of fossil echinoderms known from the Miocene of Jamaica, including at least ten species in four classes. This fauna is comprised of the isocrinid crinoids Neocrinus sp. cf. N. decorus (Wyville Thomson) and Isocrinus sp.; the ophiuroid Ophiomusium? sp.; the asteroids Astropecten? spp.; and the echinoids Prionocidaris? sp., Histocidaris sp., Echinometra sp. cf.

Novel Paraconiothyrium species on stone fruit trees and other woody hosts
Provedor de dados: 16
Autores: Damm, U.; Verkley, G.J.M.; Crous, P.W.; Fourie, P.H.; Haegi, A.; Riccioni, L.
Coniothyrium-like fungi are common wood and soil inhabitants and hyperparasites on other fungi. They belong to different fungal genera within the Pleosporales. Several isolates were obtained on wood of different Prunus species (plum, peach and nectarine) from South Africa, on Actinidia species from Italy and on Laurus nobilis from Turkey. Morphological and cultural characteristics as well as DNA sequence data (5.8S nrDNA, ITS1, ITS2, partial SSU nrDNA) were used to characterise them. The isolates belonged to three species of the recently established genus Paraconiothyrium. This is the first report of Paraconiothyrium brasiliense on Prunus spp. from South Africa. Two new species are described, namely Paraconiothyrium variabile sp. nov. on Prunus persica and...

Juglanconis gen. nov. on Juglandaceae, and the new family Juglanconidaceae (Diaporthales)
Provedor de dados: 16
Autores: Voglmayr, H.; Castlebury, L.A.; Jaklitsch, W.M.
Molecular phylogenetic analyses of ITS-LSU rDNA sequence data demonstrate that Melanconis species occurring on Juglandaceae are phylogenetically distinct from Melanconis s.str., and therefore the new genus Juglanconis is described. Morphologically, the genus Juglanconis differs from Melanconis by light to dark brown conidia with irregular verrucae on the inner surface of the conidial wall, while in Melanconis s.str. they are smooth. Juglanconis forms a separate clade not affiliated with a described family of Diaporthales, and the family Juglanconidaceae is introduced to accommodate it. Data of macro- and microscopic morphology and phylogenetic multilocus analyses of partial nuSSU-ITS-LSU rDNA, cal, his, ms204, rpb1, rpb2, tef1 and tub2 sequences revealed...

Culturable mycobiota from Karst caves in China, with descriptions of 20 new species
Provedor de dados: 16
Autores: Zhang, Z.F.; Liu, F.; Zhou,, X.; Liu, X.Z.; Liu, S.J.; Cai, L.
Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014–2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 116 genera, while 23.5 % were not identified to species level. Among these species, 85.8 % (211 species) belonged to Ascomycota; 7.3 % (18 species) belonged to Basidiomycota; 6.9 % (17 species) belonged to  Mucoromycotina. The majority of these species have been previously known from other environments, mostly from plants or animals as pathogens, endophytes or via a...

A new species of Pseudoniphargus (Crustacea, Amphipoda) from subterranean water of northeastern Morocco: Historical biogeography and evolutionary aspects
Provedor de dados: 16
Autores: Abiari, A. Fakher el; Oulbaz, Z.; Messouli, M.; Coineau, N.
A new species of Pseudoniphargus, P. longiflagellum (Crustacea, Amphipoda) is described from subterranean fresh water of the Riftan region of Morocco. This species is closely related to the group P. ruffoi-P. longipes, which shares several apomorphic characters. The two-step model of colonization and evolution provides an understanding of the origin and the age of this stygobiont. P. longiflagellum is derived from marine ancestors that lived in the coastal groundwater of the Tethyan South-Rifian channel during the Miocene Tortonian period. The regression of this corridor during the late Tortonian period or at the beginning of the Messinian period may have played a major role in the evolutionary history through vicariance.

Provedor de dados: 16
Autores: Rozendaal, F.G.
The use of mistnets in forest on Yamdena (Tanimbar Islands, South Moluccas, Indonesia) revealed the presence of an undescribed bush-warbler of the genus Cettia Bonaparte, 1834. The new species is described and illustrated here and its morphological characters and vocalizations are compared with those of Asian-Pacific congeners in the subgenus Horeites Hodgson, 1845. It is considered most closely related to the Southwest Pacific warblers previously known as Vitia Ramsay, 1875. In addition, the identity of Cettia bivittata Finsch, 1901, is discussed.

Autores: Trakunyingcharoen, T.; Lombard, L.; Groenewald, J.Z.; Cheewangkoon, R.; To-anun, C.; Crous, P.W.
Members of Botryosphaeriales are commonly encountered as endophytes or pathogens of various plant hosts. The Botryosphaeriaceae represents the predominant family within this order, containing numerous species associated with canker and dieback disease on a wide range of woody hosts. During the course of routine surveys from various plant hosts in Thailand, numerous isolates of Botryosphaeriaceae, including Aplosporellaceae were collected. Isolates were subsequently identified based on a combination of morphological characteristics and phylogenetic analysis of a combined dataset of the ITS and EF1-α gene regions. The resulting phylogenetic tree revealed 11 well-supported clades, correlating with different members of Botryosphaeriales. Other than confirming...

Elucidating the Ramularia eucalypti species complex
Provedor de dados: 16
Autores: Videira, S.I.R.; Groenewald, J.Z.; Kolecka, A.; Haren, L. van; Boekhout, T.; Crous, P.W.
The genus Ramularia includes numerous phytopathogenic species, several of which are economically important. Ramularia eucalypti is currently the only species of this genus known to infect Eucalyptus by causing severe leaf-spotting symptoms on this host. However, several isolates identified as R. eucalypti based on morphology and on nrDNA sequence data of the ITS region have recently been isolated from other plant hosts, from environmental samples and also from human clinical specimens. Identification of closely related species based on morphology is often difficult and the ITS region has previously been shown to be unreliable for species level identification in several genera. In this study we aimed to resolve this species-complex by applying a polyphasic...

Publishing taxonomic and systematics studies in the digital era faces major challenges and requires new approaches, many of which are currently stimulating spirited discussions amongst taxonomists and systematists. New amendments to the International Code of Zoological Nomenclature are expected to regulate electronic publishing of new taxa and create a standard form for their registration (ZooBank). Responding to a perceived need, this editorial announces establishment of ZooKeys â€“ a new online and print journal in zoological taxonomy and systematics, which aims to quickly respond and adapt to the newest developments in taxonomic publishing. Open Access is accepted as mandatory for ZooKeys. The rationale for and concept of ZooKeys is discussed in detail.

Autores: Silva, M.; Barreto, R.W.; Pereira, O.L.; Freitas, N.M.; Groenewald, J.Z.; Crous, P.W.
Although the genus Pseudocercospora has a worldwide distribution, it is especially diverse in tropical and subtropical countries. Species of this genus are associated with a wide range of plant species, including several economically relevant hosts. Preliminary studies of cercosporoid fungi from Brazil allocated most taxa to Cercospora, but with the progressive refinement of the taxonomy of cercosporoid fungi, many species were relocated to or described in Pseudocercospora. Initially, species identification relied mostly on morphological features, and thus no cultures were preserved for later phylogenetic comparisons. In this study, a total of 27 Pseudocercospora spp. were collected, cultured, and subjected to a multigene analysis. Four genomic regions...

Chaetomium globosum, the type species of the genus, is ubiquitous, occurring on a wide variety of substrates, in air and in marine environments. This species is recognised as a cellulolytic and/or endophytic fungus. It is also known as a source of secondary metabolites with various biological activities, having great potential in the agricultural, medicinal and industrial fields. On the negative side, C. globosum has been reported as an air contaminant causing adverse health effects and as causal agent of human fungal infections. However, the taxonomic status of C. globosum is still poorly understood. The contemporary species concept for this fungus includes a broadly defined morphological diversity as well as a large number of synonymies with limited...

Helvella is a widespread, speciose genus of large apothecial ascomycetes (Pezizomycete: Pezizales) that are found in terrestrial biomes of the Northern and Southern Hemispheres. This study represents a beginning on assessing species limits and applying correct names for Helvella species based on type material and specimens in the university herbaria (fungaria) of Copenhagen (C), Harvard (FH) and Oslo (O). We use morphology and phylogenetic evidence from four loci – heat shock protein 90 (hsp), translation elongation factor alpha (tef), RNA polymerase II (rpb2) and the nuclear large subunit ribosomal DNA (LSU) – to assess species boundaries in an expanded sample of Helvella specimens from Europe. We combine the morphological and phylogenetic information...

A fissitunicate ascus mechanism in the Calosphaeriaceae, and novel species of Jattaea and Calosphaeria on Prunus wood
Provedor de dados: 16
Autores: Damm, U.; Crous, P.W.; Fourie, P.H.
During a survey of Prunus wood from South Africa, isolations were made of three presumably Calosphaerialean fungi that formed hyphomycetous, phialidic anamorphs in culture. In order to reveal the phylogenetic relationship of these fungi, they were characterised on a morphological and molecular (LSU and ITS rDNA) basis. Two isolates that formed a teleomorph in culture are newly described as Calosphaeria africana sp. nov. Although asci of Calosphaeria are characterised by having non-amyloid apical rings, two functional wall layers were observed in asci of C. africana, which has hitherto not been observed in any member of the Calosphaeriaceae. However, Calosphaeriaceae (Calosphaeriales, Sordariomycetes) are not closely related to other bitunicate fungi like...

Systematic revision of the enigmatic Malagasy broad-headed frogs (Laurentomantis Dubois, 1980), and their phylogenetic position within the endemic mantellid radiation of Madagascar
Provedor de dados: 16
Autores: Vences, Miguel; Glaw, Frank; Andreone, Franco; Jesu, Riccardo; Schimmenti, Giovanni.
A revision of species included in the subgenus Laurentomantis (genus Mantidactylus) yielded new information about phylogeny, taxonomy, and biogeography of the endemic mantellid frog radiation in Madagascar. Four Laurentomantis species, distinguished by morphology and advertisement calls, are recognized: Mantidactylus (Laurentomantis) horridus (Northern and North- Western biogeographic regions), M. (L.) ventrimaculatus (South- East and East); M. (L.) malagasius (East); and the new species M. (L.) striatus (North-East). M. striatus and M. malagasius are probably sister species based on bioacoustic and morphological affinities. A tibial gland, so far unknown in anurans, is described in M. malagasius and M. horridus. A phylogenetic analysis of 54 mainly...

Systematic notes on Asian birds. 36. A preliminary review of the Chloropseidae and Irenidae
Provedor de dados: 16
Autores: Wells, D.R.; Dickinson, E.C.; Dekker, R.W.R.J.
Hypotheses of family phylogeny are summarized up to date, and amendments made to the treatment by Delacour (1960) of Chloropsis and Irena in Peters’s Check-list of Birds of the World (Mayr &amp; Greenway, 1960), at and below species level. Revision of species-limits within C. cochinchinensis (Gmelin, 1789) and C. aurifrons (Temminck, 1829) as defined in Delacour (1960) restores three ultra-taxa to species rank, boosting the global list of leafbird species to 11. Certain range and nomenclatural issues are resolved, including re-designation of the type locality of Turdus cochinchinensis, type species of Chloropsis. A new subspecies name is introduced as an outcome.

Revision of Geranium sections Azorelloida, Neoandina, and Paramensia (Geraniaceae)
Provedor de dados: 16
Autores: Aedo, C.; Aldasoro, J.J.; Navarro, C.
The sections Azorelloida, Neoandina, and Paramensia of Geranium, all of them from the Andes, are taxonomically revised. Fruits with the ‘seed ejection-type’ dispersal have been found in all species, which allows classifying them within subg. Geranium. The sections Azorelloida and Paramensia consist of one and two species respectively, while section Neoandina comprises 24 taxa. Prior to this revision, the stemless species of Geranium from the Andes have been considered to belong to sect. Andina. Geranium sessiliflorum (type of Geranium sect. Andina), however, should be included in sect. Chilensia. Therefore, recently a new sect. Neoandina has been described to include most of the sect. Andina species (Aedo, 2000). Diagnostic morphological features are...

The fi rst Microcharon (Crustacea, Isopoda, Microparasellidae) from the Moroccan North Saharan Platform. Phylogeny, origin and palaeobiogeography
Provedor de dados: 16
Autores: Aït Boughrous, A.; Boulanouar, M.; Yacoubi, M.; Coineau, N.
The interstitial stygobites of the genus Microcharon (Crustacea, Isopoda, Microparasellidae) are highly diversified in Morocco, especially in the High Atlas. A new species from the North Saharan platform is described. Microcharon oubrahimae n. sp. is characterized by the original morphology of the first male pleopod which exhibits a concave inner margin of the distal part and a subdistal position of the armature. From a phylogenetic point of view, M. oubrahimae does not belong to the lineage which includes the Moroccan Atlasian species. In contrast, it belongs to the eastern- Mediterranean group of species. It is related to the species of the group M. orghidani-M. bureschi-M. phlegetonis from Romania and Bulgaria. The two-step model of colonization and...

Niche sharing reflects a poorly understood biodiversity phenomenon
Provedor de dados: 16
Autores: Crous, P.W.; Wingfield, M.J.; Groenewald, J.Z.
Eucalyptus spp. are susceptible to a large number of foliar pathogens, some of which can cause serious defoliation and die-back. In this study, a single leaf spot on a Eucalyptus leaf collected in Madagascar revealed an unusual association of microfungi with disease symptoms. Initial observations indicated that the leaf spot was associated with Mycosphaerella marksii, a common pathogen of eucalypts. However, more intensive scrutiny showed the presence of several other microfungi co-occurring in this, and other leaf spots on the leaf. A total of 41 single conidial propagules were subsequently obtained from a single lesion for morphological study and DNA sequence comparisons. Based on these data, 11 members of the Capnodiales, including one species of...

Phylogenetic analysis of the Antarctic genus Oswaldella Stechow, 1919 (Hydrozoa, Leptomedusae, Kirchenpaueriidae)
Provedor de dados: 16
Autores: Peña Cantero, Alvaro L.; Marques, Antonio C.
A cladistic study was carried out on known species of the characteristically Antarctic genus Oswaldella, adopting as outgroups some other genera included in the family Kirchenpaueriidae. The analysis resulted in a cladogram with low CI in which no relationship between genera can be depicted. However, the hypothesis of monophyly of the genus Oswaldella is corroborated, being supported in our cladogram by five synapomorphies (although all are homoplastic with other taxa or reversed within the species of the genus). The basal relationships of the genus are uncertain, but three species groups are distinguishable within Oswaldella: 1) the O. incognita group, 2) the O. antarctica group, and 3) a clade formed by (O. garciacarrascosai, O. elongata ( O. blanconae...

Hydroids of the Allan Hancock Pacific Expeditions, and those of the Allan Hancock Caribbean Sea Expedition, were examined by Charles McLean Fraser in a series of reports published between 1938 and 1948. A total of 159 new nominal species was described from material collected in the eastern Pacific between Peru and southern British Columbia. Accounts of an additional five nominal species were based on specimens from the southern Caribbean Sea. No valid holotypes were designated in accordance with provisions of the International Code of Zoological Nomenclature for any of these taxa. The purpose of this report is to establish an objective standard for each species, and to promote stability of nomenclature in Hydrozoa, by designating lectotypes for these taxa,...

Molecular phylogeny and taxonomy of Eurasian Neoerysiphe species infecting Asteraceae and Geranium
Provedor de dados: 16
Autores: Heluta, V.; Takamatsu, S.; Harada, M.; Voytyuk, S.
Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi. Neoerysiphe hiratae is a Japanese species parasitizing hosts belonging to the genera Cacalia and Ligularia (tribe Senecioneae). Neoerysiphe joerstadii was found in Israel on Phagnalon rupestre (tribe Gnaphalieae). Neoerysiphe nevoi was recorded in Israel and Ukraine on a number of hosts in different genera but all belonging to tribe Cichorieae. Thus, Eurasian...

Autores: Camacho, Ana Isabel; Rey, Isabel; Dorda, Beatriz A.; Machordom, Annie; Valdecasas, Antonio G.
Molecular data for the mt 16S rDNA gene fragment of a bathynellacean is here presented for the first time and used to analyze the relationship of the group within the crustacean class Malacostraca (Arthropoda, Bathynellacea). Two contrasting views have classified the bathynelids as being cither within the order Syncarida or in a separate super-order Podophallocarida belonging to the infra-class Eonomostraca, a disagreement based mainly on debates over external and internal morphology. The preliminary analyses offered here in question the placement of this Bathynellacea within the Syncarida, and suggest the need for a further study of relationships among the malacostracan groups.

Removing chaos from confusion: assigning names to common human and animal pathogens in Neocosmospora
Provedor de dados: 16
Autores: Sandoval-Denis, M.; Crous, P.W.
The genus Neocosmospora encompasses highly prevalent and aggressive human and animal fungal pathogens. Here we assign formal descriptions and Latin binomials to some of the most clinically relevant phylogenetic species of the genus. Three new species, named Neocosmospora catenata, N. gamsii and N. suttoniana (previously assigned to the informal names ‘Fusarium’ solani species complex (FSSC) lineages, FSSC 43, FSSC 7 and FSSC 20, respectively) are described on the basis of multilocus phylogenetic analyses (using EF-1α, ITS, LSU and RPB2 loci) and morphological characters. Lineage FSSC 9 is conspecific with the ex-type strain of Cylindrocarpon tonkinense, thus the new combination Neocosmospora tonkinensis is proposed. In addition, and based on the latest...

Seiridium (Sporocadaceae): an important genus of plant pathogenic fungi
Provedor de dados: 16
Autores: Bonthond, G.; Sandoval-Denis, M.; Groenewald, J.Z.; Crous, P.W.
The genus Seiridium includes multiple plant pathogenic fungi well-known as causal organisms of cankers on Cupressaceae. Taxonomically, the status of several species has been a topic of debate, as the phylogeny of the genus remains unresolved and authentic ex-type cultures are mostly absent. In the present study, a large collection of Seiridium cultures and specimens from the CBS and IMI collections was investigated morphologically and phylogenetically to resolve the taxonomy of the genus. These investigations included the type material of the most important Cupressaceae pathogens, Seiridium cardinale, S. cupressi and S. unicorne. We constructed a phylogeny of Seiridium based on four loci, namely the ITS rDNA region, and partial translation elongation...

Phaeoacremonium species diversity on woody hosts in the Western Cape Province of South Africa
Provedor de dados: 16
Autores: Spies, C.F.J.; Moyo, P.; Halleen, F.; Mostert, L.
Nineteen Phaeoacremonium species are currently known in South Africa. These have been reported from grapevines, fruit trees, fynbos twig litter and arthropods. In other countries some of these Phaeoacremonium species are also known from hosts such as European olive, quince and willow that commonly occur in the Western Cape Province of South Africa, where most South African records of Phaeoacremonium have been made. The aim of this study was to investigate the species diversity and host-range of Phaeoacremonium in the Western Cape Province of South Africa by characterising 156 isolates collected from 29 woody hosts. Phylogenetic analyses of combined actin and beta-tubulin datasets allowed for the identification of 31 species among the 156 isolates,...

Genera of diaporthalean coelomycetes associated with leaf spots of tree hosts
Provedor de dados: 16
Autores: Crous, P.W.; Summerell, B.A.; Alfenas, A.C.; Edwards, J.; Pascoe, I.G.; Porter, I.J.; Groenewald, J.Z.
Four different genera of diaporthalean coelomycetous fungi associated with leaf spots of tree hosts are morphologically treated and phylogenetically compared based on the DNA sequence data of the large subunit nuclear ribosomal DNA gene (LSU) and the internal transcribed spacers and 5.8S rRNA gene of the nrDNA operon. These include two new Australian genera, namely Auratiopycnidiella, proposed for a leaf spotting fungus occurring on Tristaniopsis laurina in New South Wales, and Disculoides, proposed for two species occurring on leaf spots of Eucalyptus leaves in Victoria. Two new species are described in Aurantiosacculus, a hitherto monotypic genus associated with leaf spots of Eucalyptus in Australia, namely A. acutatus on E. viminalis, and A....

Pisorisporiales, a new order of aquatic and terrestrial fungi for Achroceratosphaeria and Pisorisporium gen. nov. in the Sordariomycetes
Provedor de dados: 16
Autores: Réblová, M.; Fournier, J.; Štěpánek, V.
Four morphologically similar specimens of an unidentified perithecial ascomycete were collected on decaying wood submerged in fresh water. Phylogenetic analysis of DNA sequences from protein-coding and ribosomal nuclear loci supports the placement of the unidentified fungus together with Achroceratosphaeria in a strongly supported monophyletic clade. The four collections are described as two new species of the new genus Pisorisporium characterised by non-stromatic, black, immersed to superficial perithecial ascomata, persistent paraphyses, unitunicate, persistent asci with an amyloid apical annulus and hyaline, fusiform, cymbiform to cylindrical, transversely multiseptate ascospores with conspicuous guttules. The asexual morph is unknown and no conidia...

Novel Curvularia species from clinical specimens
Provedor de dados: 16
Autores: Madrid, H.; da Cunha, K.C.; Gené, J.; Dijksterhuis, J.; Cano, J.; Sutton, D.A.; Guarro, J.; Crous, P.W.
The fungal genus Curvularia includes numerous plant pathogens and some emerging opportunistic pathogens of humans. In a previous study we used morphology and sequences of the nuclear ribosomal internal transcribed spacer region (ITS) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene to identify species within a set of 99 clinical Curvularia isolates from the USA. Seventy-two isolates could be identiﬁed while the remaining 27 isolates belonged in three unclassiﬁed clades that were tentatively labelled Curvularia sp. I, II and III. In the present study, we further assess the taxonomic placement of these isolates using sequences of ITS, gpd, the large subunit rDNA, and the second largest subunit of RNA polymerase II. DNA sequence comparisons with a...

Generic circumscriptions in Geoglossomycetes
Provedor de dados: 16
Autores: Hustad, V.P.; Miller, A.N.; Dentinger, B.T.M.; Cannon, P.F.
The class Geoglossomycetes is a recently created class of Ascomycota, currently comprised of one family (Geoglossaceae) and five genera (Geoglossum, Nothomitra, Sarcoleotia, Thuemenidium and Trichoglossum). These fungi, commonly known as earth tongues, have long been a subject of mycological research. However, the taxonomy within the group has historically been hindered by the lack of reliable morphological characters, uncertain ecological associations, and the inability to grow these fungi in culture. The phylogenetic relationships of Geoglossomycetes were investigated by conducting maximum likelihood and Bayesian analyses using a 4-gene dataset (ITS, LSU, MCM7, RPB1). Five well-supported monophyletic clades were found that did not correspond exactly with...

Contribution to the knowledge of the Proseriata (Platyhelminthes: Seriata) from eastern Australia. II. Genera Pseudomonocelis Meixner, 1943 and Acanthopseudomonocelis n. g
Provedor de dados: 16
Autores: Curini-Galletti, Marco; Cannon, Lester.
Two monocelid species with simplex copulatory bulbs and postpharyngeal ovaries have been found in E. Australia. One of them presents a combination of characters not found in any of the known genera of the Monocelididae, and the new genus Acanthopseudomonocelis is proposed for it. The new genus is characterized by the presence of four stylet-bearing accessory organs and by an internal vagina; it is related to Pseudomonocelis. The other species, Pseudomonocelis schockaerti n. sp., is characterized by a complex bursa-vagina system, and by a highly muscular penial organ and male antrum. It is closely related to P. pardii Schockaert &amp; Martens, 1987, from Somaliland. Two possibly additional species of the genus Pseudomonocelis, not found in a mature stage,...

Archaeocidaris M’Coy (Echinoidea) from the Carboniferous of Egypt
Provedor de dados: 16
Autores: Lewis, D.N.; Donovan, S.K.
Collections in museums usually have boxes of specimens which remain ‘undiscovered’ and yet which may be of importance or interest. The recent rediscovery of specimens of Archaeocidaris in the Nationaal Natuurhistorisch Museum, Leiden, from the Carboniferous of Egypt illustrates this point. These specimens were collected in 1938 by Dr. H.M.E. Schürmann (1891-1979), who had been a student of Professor J. Wanner (1878-1956), the noted expert on fossil echinoderms. The Egyptian Archaeocidaris plates include interambulacrals and radioles. These are closest to Archaeocidaris rossica (von Buch) from the Moscow area of Russia, although there are sufficient differences in radiole morphology to suggest that they are not necessarily conspecific.

The scleractinian family Lobophylliidae is undergoing a major taxonomic revision thanks to the combination of molecular and morphological data. In this study, we investigate the evolutionary relationships and the macro- and micromorphology of six nominal coral species belonging to two of the nine molecular clades of the Lobophylliidae, clades A and B, and of Symphyllia wilsoni, a lobophylliid species analyzed from a molecular point of view for the first time. Sequence data from mitochondrial DNA (COI and the intergenic spacer between COI and l-rRNA), and nuclear DNA (histone H3 and ITS region) are used to generate robust molecular phylogenies and a median-joining haplotype network. Molecular results are strongly in agreement with detailed observations of...

‘Cort short on a mountaintop’ – Eight new species of sequestrate Cortinarius from sub-alpine Australia and affinities to sections within the genus
Provedor de dados: 16
Autores: Danks, M.; Lebel, T.; Vernes, K.
During the course of research on mammal mycophagy and movement in the Northern Tablelands of New South Wales, Australia, extensive collections of sequestrate fungi were made, including numerous cortinarioid taxa. Historically any novel taxa would have been described in the cortinarioid sequestrate genera Descomyces, Hymenogaster, Protoglossum, Quadrispora, Thaxterogaster or Timgrovea based on broad morphological similarities of the sporocarps and spore ornamentation. However, consistent with other recent analyses of nuclear DNA regions, taxa from sequestrate genera were found to have affinities with Cortinarius and Descolea or Hebeloma, and to be scattered across many sections within Cortinarius. None of the historical sequestrate cortinarioid genera are...

Phylogenetic reassessment of Nigrospora: Ubiquitous endophytes, plant and human pathogens
Provedor de dados: 16
Autores: Wang, M.; Liu, F.; Crous, P.W.; Cai, L.
Species of Nigrospora commonly occur as plant pathogens, endophytes or saprobes, and have been shown to be extremely interesting for the discovery of novel metabolites. The familial placement, as well as phylogenetic relationships among Nigrospora species remain ambiguous. In this study, Nigrospora (= Khusia) is confirmed as a monophyletic genus belonging to Apiosporaceae (Xylariales), based on a phylogeny inferred from LSU sequence data. A multi-locus phylogeny based on ITS, TEF1-α and TUB2, in conjunction with morphological characters, host associations, and ecological data was employed for species delimitation in Nigrospora, as well as identification of 165 recently collected isolates from China, and three from Europe. In total 13 novelties are proposed...

Systematic value of the ultrastructure of the sucker surface in the squid family Mastigoteuthidae (Mollusca: Cephalopoda)
Provedor de dados: 16
Autores: Salcedo-Vargas, Mario Alejandro.
The ultrastructure of the sucker surface is described and its systematic value for mastigoteuthid squids, which bear minute suckers, is considered. An introduction to sucker terms is given and a redefinition of these terms is attempted. Using scanning electron microscopic data, two genera and four subgenera of Mastigoteuthidae from the Northwest Pacific are distinguished. The presence of “cushions” in the sucker is discussed and considered as a character important for understanding adaptations of cephalopods to the deep-sea.

Provedor de dados: 16
Autores: Geissmann, Thomas; Groves, Colin P.; Roos, Christian.
The Tenasserim lutung Trachypithecus barbei was previously known from museum specimens and field observations only. We discovered a zoo specimen and present the first confirmed evidence for the continued existence of the species since 1967. We describe the cranial pelage and coloration characteristics of this species which were previously unknown. We present first molecular evidence for recognizing T. barbei as a distinct species and for assessing its phylogenetic affinities relative to other members of the genus Trachypithecus. We document the taxonomic history of T. barbei and present a distribution map based on a compilation of all known locality records.

Intraspecific and intrageneric variabilities and their implication for the systematics of Cretaceous heteromorph ammonites; a review
Provedor de dados: 16
Autores: Kakabadze, M.V.
The variability in the dimensions of the shell, and some changes in suture line, sculpture, whorl section and mode of coiling in the late ontogenetic stages, have in some cases no taxonomic significance for the recognition of genera and higher taxa of Cretaceous heteromorph ammonites. In many cases, such phenomena are due to intraspecific variation or variation within a genus. The intrageneric variations of some Cretaceous heteromorphs are discussed in detail in the light of new, rich Colombian material. In relation to these problems in systematics, some questions on the systematics of the superfamily Ancyloceratoidea Gill are considered.

Calonectria spp. causing leaf spot, crown and root rot of ornamental plants in Tunisia
Provedor de dados: 16
Autores: Lombard, L.; Polizzi, G.; Guarnaccia, V.; Vitale, A.; Crous, P.W.
Calonectria spp. are important pathogens of ornamental plants in nurseries, especially in the Northern Hemisphere. They are commonly associated with a wide range of disease symptoms of roots, leaves and shoots. During a recent survey in Tunisia, a number of Calonectria spp. were isolated from tissues of ornamental plants showing symptoms of leaf spot, crown and root rot. The aim of this study was to identify these Calonectria spp. using morphological and DNA sequence comparisons. Two previously undescribed Calonectria spp., C. pseudomexicana sp. nov. and C. tunisiana sp. nov., were recognised. Calonectria mexicana and C. polizzii are newly reported for the African continent. Pathogenicity tests with all four Calonectria spp. showed that they are able to...

In March 2000 and November/December 2001 thirteen specimens of Corallimorphus profundus Moseley, 1877, a conspicuous, anemone-like cnidarian, were hand-sampled by SCUBA diving in 30 to 40 m depth off US Palmer Station, Antarctic Peninsula. Corallimorphus species were formerly recorded only from deep water habitats from where they had been brought up more or less damaged, with most of their epithelia lost or macerated. The present well preserved specimens offer the opportunity to study various aspects of the species’ morphology and biology, particularly as one mature female contained a full cycle of oogenesis besides two batches of brooded developmental stages. Most of the results obtained demonstrate that the genus Corallimorphus shows features and...

Uromycladium tepperianum has been reported on over 100 species of Acacia, as well as on the closely related plant genera, Falcataria, Racosperma and Paraserianthes. Previous studies have indicated that U. tepperianum may represent a complex of host-specific, cryptic species. The phylogenetic relationships between 79 specimens of Uromycladium were determined based on a concatenated dataset of the Small Subunit, the Internal Transcribed Spacer and the Large Subunit regions of nuclear ribosomal DNA, and the mitochondrial cytochrome c oxidase subunit 3. This study showed that the host range of U. tepperianum s.str. was restricted to species of Acacia in the ‘A. bivenosa group’ sensu Chapman &amp; Maslin (1992).

Novel micromorphological characters in combination with molecular studies have led to an extensive revision of the taxonomy and systematics of scleractinian corals. In the present work, we investigate the macro- and micromorphology and the phylogenetic position of the genera Australomussa and Parascolymia, two monotypic genera ascribed to the family Lobophylliidae. The molecular phylogeny of both genera was addressed using three markers, the partial mitochondrial COI gene and the nuclear histone H3 and the ribosomal ITS region. Based on molecular data, Australomussa and Parascolymia belong to the Lobophylliidae and they cluster together with the genera Lobophyllia and Symphyllia within the same clade.

The Mycosphaerella complex is both poly- and paraphyletic, containing several different families and genera. The genus Mycosphaerella is restricted to species with Ramularia anamorphs, while Septoria is restricted to taxa that cluster with the type species of Septoria, S. cytisi, being closely related to Cercospora in the Mycosphaerellaceae. Species that occur on graminicolous hosts represent an as yet undescribed genus, for which the name Zymoseptoria is proposed. Based on the 28S nrDNA phylogeny derived in this study, Zymoseptoria is shown to cluster apart from Septoria. Morphologically species of Zymoseptoria can also be distinguished by their yeast-like growth in culture, and the formation of different conidial types that are absent in Septoria s.str....

Diaporthe (Phomopsis) species have often been reported as plant pathogens, non-pathogenic endophytes or saprobes, commonly isolated from a wide range of hosts. The primary aim of the present study was to resolve the taxonomy and phylogeny of a large collection of Diaporthe species occurring on diverse hosts, either as pathogens, saprobes, or as harmless endophytes. In the present study we investigated 243 isolates using multilocus DNA sequence data. Analyses of the rDNA internal transcribed spacer (ITS1, 5.8S, ITS2) region, and partial translation elongation factor 1-alpha (TEF1), beta-tubulin (TUB), histone H3 (HIS) and calmodulin (CAL) genes resolved 95 clades. Fifteen new species are described, namely Diaporthe arengae, D. brasiliensis, D. endophytica,...

Barriopsis iraniana and Phaeobotryon cupressi: two new species of the Botryosphaeriaceae from trees in Iran
Provedor de dados: 16
Autores: Abdollahzadeh, J.; Mohammadi Goltapeh, E.; Javadi, A.; Shams-bakhsh, M.; Zare, R.; Phillips:, A.J.L.
Species in the Botryosphaeriaceae are well known as pathogens and saprobes of woody hosts, but little is known about the species that occur in Iran. In a recent survey of this family in Iran two fungi with diplodia-like anamorphs were isolated from various tree hosts. These two fungi were fully characterised in terms of morphology of the anamorphs in culture, and sequences of the ITS1/ITS2 regions of the ribosomal DNA operon and partial sequences of the translation elongation factor 1-α. Phylogenetic analyses placed them within a clade consisting of Barriopsis and Phaeobotryon species, but they were clearly distinct from known species in these genera. Therefore, they are described here as two new species, namely Barriopsis iraniana on Citrus, Mangifera and...

Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia
Provedor de dados: 16
Autores: Wesselingh, F.P.; Anderson, L.C.; Kadolsky, D.
The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachyrotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two families, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be characterised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few...

Provedor de dados: 16
Autores: Sanz, Sebastián; Platvoet, Dirk.
On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the...

Two new Brazilian species of Tachia (Gentianaceae: Helieae)
Provedor de dados: 16
Autores: Struwe, L.; Kinkade, M.P.; Maas, P.J.M.
Two new species of Tachia (Gentianaceae: Helieae) are described from Brazil. They share the unusual characteristic of quadrangular, winged stems, formerly only known from Tachia longipes in Suriname. They differ from this species in their larger, winged, keeled, and long-acuminate calyx lobes. Tachia lancisepala, spec. nov., is only known from one collection from the State of Rondônia in Brazil, and has unusually large and broadly funnelshaped corollas and ovate leaves with winged petioles. Tachia siwertii, spec. nov., has been found in three separate areas in southern Amazonas and Pará (Brazil) and is characterized by more elliptic leaves, unwinged petioles, and a narrower corolla than T. lancisepala.

The value of the D1/D2 and internal transcribed spacers (ITS) domains for the identification of yeast species belonging to the genus Yamadazyma
Provedor de dados: 16
Autores: Groenewald, M.; Robert, V.; Smith, M.Th.
In a taxonomic study of yeasts that have been isolated in French Guiana and Thailand, five yeast strains isolated from plants were found to belong to the Yamadazyma clade of Saccharomycotina. On the basis of morphology, physiology and the nucleotide divergence in the D1/D2 domain of the 26S nuclear ribosomal RNA (nrRNA) gene, as well as the internal transcribed spacers (ITS) domain of the nrRNA gene operon, these strains were identified to represent three novel species in this teleomorphic clade. An additional isolate, that is publicly available from the CBS yeast collection and isolated from Taiwan, was found to be similar to one of the novel species described from Thailand. Yeast species belonging to the Yamadazyma clade have previously been described as...

Autores: Costa-Rezende, D.H.; Robledo, G.L.; Góes-Neto, A.; Reck, M.A.; Crespo, E.; Drechsler-Santos, E.R.
Ganodermataceae is a remarkable group of polypore fungi, mainly characterized by particular doublewalled basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify relationship of Neotropical Amauroderma s.lat. within the Ganodermataceae family, morphological analyses, including scanning electron microscopy, as well as a molecular phylogenetic approach based on one (ITS) and four loci (ITS-5.8S, LSU, TEF-1α and RPB1), were carried out. Ultrastructural analyses raised up a new character for Ganodermataceae systematics, i.e., the presence of perforation in the exosporium with holes that are connected with hollow...

Provedor de dados: 16
Autores: Silveira, Fábio Lang da; Morandini, André Carrara.
Nausithoe aurea, a new species of scyphozoan Coronatae, is described from São Paulo State, Brazil. The solitary scyphistomae, with some zooxanthellae, strobilated producing planuloids and medusae; this represents an intermediate life cycle between that of metagenetic Nausithoidae and the submarine cave-dwelling, reduced medusa stage of Nausithoe planulophora (Werner, 1971). The periderm tube of the scyphistomae has 16 internal cusps in all whorls. The medusae present yellow pigment spots in most of their lappets. The early embryonic development is briefly described. Planuloid formation is hypothesized as explanation for polyp-stage philopatry.

Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Callaghan, B.; Vánky, K.; Scharaschkin, T.
The genera Ustilago, Sporisorium and Macalpinomyces are a polyphyletic complex of plant pathogenic fungi. The four main morphological characters used to define these genera have been considered homoplasious and not useful for resolving the complex. This study re-evaluates character homology and discusses the use of these characters for defining monophyletic groups recovered from a reconstructed phylogeny using four nuclear loci. Generic delimitation of smut fungi based on their hosts is also discussed as a means for identifying genera within this group. Morphological characters and host specificity can be used to circumscribe genera within the Ustilago-Sporisorium-Macalpinomyces complex.

Finding the missing link: resolving the Coryneliomycetidae within Eurotiomycetes
Provedor de dados: 16
Autores: Wood, A.R.; Damm, U.; Linde, E.J. van der; Groenewald, J.Z.; Cheewangkoon, R.; Crou, P.W.
Species belonging to the Coryneliaceae and parasitizing Podocarpaceae hosts were collected from different locations in South Africa and studied morphologically by light microscopy and molecularly by obtaining partial nrDNA (ITS-1/5.8S/ITS-2, 18S and 28S) gene sequences. The position of the Coryneliaceae within the Eurotiomycetidae was not confirmed and a new subclass, Coryneliomycetidae, was introduced. While Eurotiomycetidae usually form cleistothecia/gymnothecia with evanescent, unitunicate asci, and Chaetothyriomycetidae mostly perithecia with bitunicate/fissitunicate to evanescent asci, Coryneliomycetidae form pseudothecial mazaedial ascomata, initially with double-walled asci with the outer layer deliquescing, resulting in passive ascospore release....

Autores: Jong, R. de.
The genus Taractrocera is distributed throughout the Oriental and Australian Regions. It contains 16 species, of which two, T. fusca and T. trikora, are described as new in this paper. All species are briefly characterized and the new species are described in full. The phylogeny of the genus is inferred, based on an analysis of morphological and genital characters, both of males and females. The biogeography of the genus is discussed in relation to the phylogeny. The genus has an Australian origin. After some diversification in Australia it dispersed into Asia, in or before the Miocene. It dispersed in the reverse direction, probably before the late-Miocene emergence of the Banda Arc and the Moluccas, 5-6 Mya. Three species are adapted to high altitude,...

Towards a systematic standard approach to describing fossil crinoids, illustrated by the redescription of a Scottish Silurian Pisocrinus de Koninck
Provedor de dados: 16
Autores: Fearnhead, F.E.
Systematic taxonomy requires thoughtful, detailed and structured descriptions of species characters, and essential additional data for effective comparison with other specimens. Crinoid terminology is commonly misused or at best confused. The purpose of this paper is to facilitate this process by encouraging a standard methodology which would make comparisons of fossil crinoid taxa easier for all. An ordered tabulation of those characters that should be considered in any description of a fossil crinoid is provided and implemented in describing a Scottish Llandovery (Lower Silurian) disparid crinoid Pisocrinus cf. campana S.A.

Trichoderma viridescens is recognised as a species complex. Multigene analyses based on the translation elongation factor 1-alpha encoding gene (tef1), a part of the rpb2 gene, encoding the second largest RNA polymerase subunit and the larger subunit of ATP citrate lyase (acl1) reveals 13 phylogenetic species with little or no phenotypic differentiation. This is the first use of acl1 in Trichoderma phylogenetics. The typification of T. viridescens s.str. is clarified and Hypocrea viridescens is replaced by the new name T. paraviridescens. Besides these two species, eleven are phylogenetically recognised and T. olivascens, T. viridarium, T. virilente, T. trixiae, T. viridialbum, T. appalachiense, T. neosinense, T. composticola, T. nothescens and T....

Autores: Pickerill, R.K.; Donovan, S.K.; Portell, R.W.
The ichnotaxon Teredolites Leymerie, 1842, represented by T. longissimus Kelly &amp; Bromley, 1984, is documented for the first time from the Lesser Antilles. Its occurrence also represents the first record of the ichnotaxon from the Miocene of the Caribbean. Five specimens, each occurring in isolation without an enclosing xylic (wood) substrate, but merely calcite-lined tubes, occur in the Miocene Grand Bay Formation of Carriacou, the Grenadines, Lesser Antilles. Stratinomic considerations suggest that following physical destruction or biological decomposition of their enclosing substrate(s), the tubes may have accumulated in relatively shallow water only to be subsequently resedimented into a deeperwater (&gt; 150 m) environment.

Knowledge of insect diversity in Brazil: challenges and advances
Provedor de dados: 82
Autores: Rafael,José A; Aguiar,Alexandre P; Amorim,Dalton de S.
Insects will soon reach one million known species worldwide. Brazil, with about 9% of this total, and possibly another 400 thousand species yet to be discovered, harbors the highest insect diversity in the world. The country has a complement of about 140 active taxonomists, which means a quota of 3,600 insect species per professional. Each Brazilian taxonomist publishes, on average, about 100 species during a professional life span, so it would take 2-3 thousand years to only know the country's insect diversity. Some of the problems hindering the development of insect taxonomy in Brazil are: difficulties with international loans; difficulties with permission for dissecting loaned type specimens; low scientific esteem of taxonomic journals as assessed by...

Barcoding lepidoptera: current situation and perspectives on the usefulness of a contentious technique
Provedor de dados: 82
Autores: Silva-Brandão,Karina L; Lyra,Mariana L; Freitas,André V L.
Faced by a growing need of identification and delimitation of new and established cryptic species that are being lost at an increasing rate, taxonomists can now more than ever take advantage of an enormous variety of new molecular and computational tools. At this moment they should be open to all new available technologies in the so called "technology-driven revolution" in systematics. The use of the "DNA barcode" has been discussed by those applying successfully this approach to identify and diagnose species and by those who believe that the flaws in the use of this molecular marker are as many as to negate the worth of its employment. For insects of the order Lepidoptera neither side seems totally correct orwrong, and although many groups of...

The loricariid catfish genus Lasiancistrus (Siluriformes) with descriptions of two new species
Provedor de dados: 83
Autores: Armbruster,Jonathan W.
Lasiancistrus (Loricariidae: Hypostominae: Ancistrini) is diagnosed by the unique presence of a ventral strut of the pterotic and the presence of whiskerlike odontodes on the snout. Lasiancistrus has about 16 species assigned to it; however, only four are valid (L. schomburgkii, L. caucanus, L. guacharote, and L. heteracanthus), L. nationi is an Ancistrus, and L. trinitatus is incertae sedis in the Loricariidae. Lasiancistrus maracaiboensis and L. mystacinus are synonyms of L. guacharote; L. pictus, L. castelnaui, L. caquetae, L. guapore, L. multispinis, and L. scolymus are synonyms of L. schomburgkii; and L. planiceps, L. mayoloi, and L. volcanensis are synonyms of L. caucanus.

Autores: Reis,Roberto E.
ABSTRACT A taxonomic revision of Eurycheilichthys is provided, and seven new species are described in addition to the two previously known species in this genus: E. pantherinus from the upper rio Uruguay, and E. limulus from the upper rio Jacuí. The genus is diagnosed based on the uniquely derived presence of seven branched pectoral-fin rays, and on the possession of reduced filamentous gill rakers in the oral surface of the hyobranchial skeleton, and presence of a distinct fleshy flap along the posterodorsal margin of the pectoral-fin spine in adult males. The seven new species are described from tributaries to the rio Taquari basin, itself a tributary to the rio Jacuí in Rio Grande do Sul State, southern Brazil. The new species are diagnosed based on...

A new species of sand-dwelling catfish, with a phylogenetic diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae)
Provedor de dados: 83
Autores: Pinna,Mário C. C. de; Kirovsky,Alexandre L.
A new species of sand-dwelling catfish genus Pygidianops, P. amphioxus, is described from the Negro and lower Amazon basins. The new species differs from its three congeners in the elongate eel-like body, the short barbels, and the small caudal fin, continuous with the body, among other traits of internal anatomy. The absence of anal fin further distinguishes P. amphioxus from all other Pygidianops species except P. magoi and the presence of eyes from all except P. cuao. The new Pygidianops seems to be the sister species to P. magoi, the two species sharing a unique mesethmoid with a dorsally-bent tip lacking cornua, and a produced articular process in the palatine for the articulation with the neurocranium. Pygidianops amphioxus is a permanent and...

A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysusand Liosomadoras, and...

Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy
Provedor de dados: 83
Autores: Mirande,Juan Marcos.
The family Characidae is the most diverse among Neotropical fishes. Systematics of this family are mainly based on pre-cladistic papers, and only recently a phylogenetic hypothesis for Characidae was proposed by the author. That phylogeny was based on 360 morphological characters studied for 160 species, including representatives of families related to Characidae. This paper is based on that phylogenetic analysis, with the analyzed characters described herein and documented, accompanied by comparisons of their definition and coding in previous papers. Synapomorphies of each node of the proposed phylogeny are listed, comparisons with previous classifications provided, and autapomorphies of the analyzed species listed. Taxonomic implications of the proposed...

Cynolebias parnaibensis, a new seasonal killifish from the Caatinga, Parnaíba River basin, northeastern Brazil, with notes on sound producing courtship behavior (Cyprinodontiformes: Rivulidae)
Provedor de dados: 83
Autores: Costa,Wilson J. E. M.; Ramos,Telton P. A; Alexandre,Luisa C; Ramos,Robson T. C.
Cynolebias parnaibensis from the Canindé River drainage, Parnaíba River basin, northeastern Brazil, is described. It is considered to be a member of a clade endemic to the Caatinga. The clade is diagnosed, e. g., by a series of structural modifications of the pharyngeal jaw apparatus, which is related to the sound production exhibited by males during courtship behavior. The courtship sound of C. parnaibensis consists of a single pulse named as thump (duration 0.031-0.133s; interthump intervals 0.020-8.319s; dominant frequency 70.3-93.8 Hz). The new species is distinguished from all other congeners by a combination of 27-31 neuromasts around eye, 29-33 supraorbital neuromasts, 16-18 dorsal-fin rays and 19 anal-fin rays in males, 28-31 caudal-fin rays, 33-36...

A redescription of deep-channel ghost knifefish, Sternarchogiton preto (Gymnotiformes: Apteronotidae), with assignment to a new genus
Provedor de dados: 83
Autores: Bernt,Maxwell J.; Fronk,Aaron H.; Evans,Kory M.; Albert,James S.
ABSTRACT From a study of morphological and molecular datasets we determine that a species originally described as Sternarchogiton preto does not form a monophyletic group with the other valid species of Sternarchogiton including the type species, S. nattereri. Previously-published phylogenetic analyses indicate that this species is sister to a diverse clade comprised of six described apteronotid genera. We therefore place it into a new genus diagnosed by the presence of three cranial fontanels, first and second infraorbital bones independent (not fused), the absence of an ascending process on the endopterygoid, and dark brown to black pigments over the body surface and fins membranes. We additionally provide a redescription of this enigmatic species with...

Autores: Menezes,Naércio A.; Lucena,Carlos Alberto S. de.
The species of Charaxwere reviewed by Lucena (1987) who a little later (1989) added three new species to the genus. Examination of recently collected specimens from museum collections documented the more extensive geographic distribution for most species and revealed the existence of a new species in which superficial neuromasts were discovered and are herein described. These skin structures were also detected in C. metae Eigenmann, 1922. Anal- and pelvic-fin hooks previously observed only on the anal-fin of one species of the genus are described herein in some other species. Charax unimaculatus Lucena is considered a junior synonym of C. michaeli Lucena. All the species are redescribed and the new species described.

Trichomycterus igobi, a new catfish species from the rio Iguaçu drainage: the largest head in Trichomycteridae (Siluriformes: Trichomycteridae)
Provedor de dados: 83
Autores: Wosiacki,Wolmar B.; Pinna,Mário de.
A new species of Trichomycterus is described for the rio Iguaçu drainage in Southern Brazil. Trichomycterus igobi, new species, is readily distinguishable from all other species currently in the genus by its extremely large head (23.8-26.8 % SL), which is proportionally the largest head in any Trichomycteridae. That characteristic plus the relatively deep body result in a very short-bodied overall aspect, the most extremely such case in the genus Trichomycterus. Other diagnostic features that distinguish the new species from most or all of its congeners include a short caudal peduncle (15.4-19.7 % SL); an almost entirely cartilaginous second hypobranchial (with only vestigial ossification); a mesial expanded palatine ossification; a narrow cleithrum,...

Miniature catfishes of the genus Gelanoglanis (Siluriformes: Auchenipteridae): monophyly and the description of a new species from the upper rio Tapajós basin, Brazil
Provedor de dados: 83
Autores: Calegari,Bárbara B.; Reis,Roberto E.; Vari,Richard P.
Previously proposed synapomorphies for the genus Gelanoglanis of the catfish family Auchenipteridae are evaluated and four additional features involving the relationship between the mesethmoid and premaxilla, the very fleshy anterior portion of the snout, the lack of ossification of the second through fourth infraorbitals, and the incomplete poring of the lateral line are hypothesized as synapomorphic for the members of the genus. A new species of Gelanoglanis is described based on a series of specimens collected in the rio Teles Pires, a tributary of the rio Tapajós in the southern reaches of the Amazon basin. The new species demonstrates a number of features unusual within Gelanoglanis including a fontanel bordered by the frontals, a particularly...

Two new species of Hypoptopomatinae from the rio Paraíba do Sul basin, with comments on the monophyly of Parotocinclus and the Otothyrini (Siluriformes: Loricariidae)
Provedor de dados: 83
Autores: Gauger,Marco F. W.; Buckup,Paulo Andreas.
Two new species of loricariid catfishes, Parotocinclus bidentatus and P. muriaensis, are described from the rio Paraíba do Sul basin. They possess accessory unicuspid teeth located internally to the series of bicuspid teeth in premaxillary and dentary bones. According to a parsimony analysis of phylogenetic relationships among the Hypoptopomatinae, the new taxa are members of the genus Parotocinclus, even though they lack a fully developed adipose fin. They differ from most species of Parotocinclus because they have accessory teeth. Within the Hypoptopomatinae, accessory teeth are also found only in P. collinsae and members of the genera Eurycheilichtys, Epactionotus and Niobichthys.

ABSTRACT A new species of the Copionodontinae genus Copionodon is described from the riacho do Mosquito, tributary to rio Santo Antônio, rio Paraguaçu basin in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known and is a relictual population, apparently restricted to an underground sector of the stream and its immediate downstream exit. The new species can be readily recognized by the combination of the presence of opercular odontodes, the mostly uniform coloration of the body, and the lack of a free orbital rim. Despite several troglomorphic traits shared between the new species and Glaphyropoma spinosum, the two species are not closest relatives and all such similarities...

Autores: Pinna,Mario de; Burger,Rafael; Zanata,Angela Maria.
ABSTRACT A new species of the copionodontine genus Copionodon is described from the upper reaches of a tributary to the rio Paraguaçu in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known. The new species can be readily recognized by its large eye without a free orbital rim. Other characters such as the entirely cartilaginous second hypobranchial, and the uniformly broad irregular midlateral dark band further diagnose the new taxon. Its particular combination of characters is superficially intermediate between Copionodon and Glaphyropoma. Detailed analysis, however, indicates that it forms a monophyletic group with species of Copionodon and therefore it should be included...

ABSTRACT Catfishes of the family Astroblepidae form a group composed by 82 valid species of the genus Astroblepus inhabiting high-gradient streams and rivers throughout tropical portions of the Andean Cordillera. Little has been advanced in the systematics and biodiversity of astroblepids other than an unpublished thesis, a single regional multilocus study and isolated species descriptions. Here, we examined 208 specimens of Astroblepus that apparently belong to 16 valid species from several piedmont rivers from northern Colombia to southern Peru. Using three single-locus approaches for species delimitation in combination with a species tree analysis estimated from three mitochondrial genes, we identified a total of 25 well-delimited lineages including...

Provedor de dados: 83
Autores: Ingenito,Leonardo F. S.; Duboc,Luiz F.
Astyanax eremus, a new species of geographically isolated characid fish, is described from a small tributary of the upper rio Iguaçu basin. The new species belongs to the Astyanax scabripinnisspecies complex and is easily distinguished from its congeners included in this group by its allometric growth of the mouth, which goes from terminal in young individuals to subterminal mouth in larger specimens. Additionally, the new species is distinguished by meristic and morphometric characters. Astyanax eremus presents an evident polymorphism on the traditional character "number of teeth in inner premaxillary row". Comments about that character are provided.

ABSTRACT Studies on the diversity, taxonomy, phylogeny, and biogeography of Neotropical Fishes have thrived over the twenty years that have elapsed since the first symposium on their phylogeny and classification in Porto Alegre, Brazil. Here, we review recent advances in the study of Neotropical fishes and assess the known diversity of freshwater species in that region. 6,255 valid freshwater species have been discovered in the Neotropics so far, and we estimate that over 9,000 species will be known when the inventory is complete. We also summarize the events of the second Symposium on Phylogeny and Classification of Neotropical Fishes that took place last year in Londrina, Brazil. Along with invited talks on the biodiversity of all major groups of...

Hemigrammus ataktos: a new species from the rio Tocantins basin, central Brazil (Characiformes: Characidae)
Provedor de dados: 83
Autores: Marinho,Manoela M. F.; Dagosta,Fernando C. P.; Birindelli,José L. O.
A new species of Hemigrammus is described from the middle rio Tocantins basin, central Brazil. The new species can be distinguished from all congeners by having a black midlateral stripe on the body extending from the posterior margin of the eye to the median caudal-fin rays. Mature males possess dorsal-, pelvic-, and anal-fin rays elongate, features that also help to recognize the new species. Although the new species is described in Hemigrammus, some specimens present a complete series of pored scales in the lateral line. A discussion about the generic allocation of the new species is presented.

Monophyly of Heterandriini (Teleostei: Poeciliidae) revisited: a critical review of the data
Provedor de dados: 83
Autores: Morales-Cazan,Alfy; Albert,James S.
The systematics and taxonomy of poeciliid fishes (guppies and allies) remain poorly understood despite the relative importance of these species as model systems in the biological sciences. This study focuses on testing the monophyly of the nominal poeciliine tribe Heterandriini and the genus Heterandria, through examination of the morphological characters on which the current classification is based. These characters include aspects of body shape (morphometrics), scale and fin-ray counts (meristics), pigmentation, the cephalic laterosensory system, and osteological features of the neurocranium, oral jaws and suspensorium, branchial basket, pectoral girdle, and the gonopodium and its supports. A Maximum Parsimony analysis was conducted of 150 characters...

Autores: Ferreira,Katiane M.; Carvajal,Fernando M.
Knodus shinahota, new species, is described from río Shinahota, a tributary of the upper rio Mamoré basin, Província de Tiraque, Cochabamba State, Bolivia. The new species can be distinguished from all congeners except K. chapadae and K. geryi by having six rows of scales between the lateral line and the dorsal-fin origin (vs 4 or 5 rows of scales in the other species). Knodus shinahota differs from K. chapadae by possessing more rows of scales between the lateral line and the pelvic-fin origin (5 vs 3½ or 4, respectively) and more lateral line scales (38-41 vs 36-38, respectively).

Comparative gross encephalon morphology in Callichthyidae (Teleostei: Ostariophysi: Siluriformes)
Provedor de dados: 83
Autores: Pupo,Fabio M.; Britto,Marcelo R.
ABSTRACT Callichthyidae comprises the subfamilies Callichthyinae and Corydoradinae, both of which are morphologically distinct and monophyletic. Although there is consensus regarding the monophyly of the family, the relationships of about 80% of its species, currently included in the genus Corydoras, remain poorly known. Despite the vast amount of osteological information for Teleostei, knowledge regarding the phylogenetic implications of encephalon anatomy is sparse and represents a poorly explored source of potential characters. The present study aims to describe the encephalon morphology in members of the Callichthyidae in order to propose new characters that may help address phylogenetic questions regarding this group. In addition to representatives of...

Description and relationships of Otothyropsis marapoama, a new genus and species of hypoptopomatine catfish (Siluriformes: Loricariidae) from rio Tietê basin, southeastern Brazil
Provedor de dados: 83
Autores: Ribeiro,Alexandre C.; Carvalho,Murilo; Melo,Alex L. A.
Otothyropsis marapoama, a new genus and species, is described based on specimens recently collected in a headwater stream of the middle stretch of the rio Tietê, a river from the upper rio Paraná basin in southeastern Brazil. The new taxon belongs to a clade also encompassing the genera Schizolecis, Otothyris and Pseudotothyris. Otothyropsis marapoama is hypothesized to be the sister-group of Pseudotothyris and Otothyris based mainly on the presence of several derived characters of the swimbladder capsule and associated bones. Several paedomorphic characters shared by Pseudotothyris and Otothyris and their significance for the phylogenetic position of the new genus are discussed.

Ontogenetic development of Heterocharax macrolepisEigenmann (Ostariophysi: Characiformes: Characidae) with comments on the form of the yolk sac in the Heterocharacinae
Provedor de dados: 83
Autores: Mattox,George M. T.; Hoffmann,Martin; Hoffmann,Peter.
Fishes in early developmental stages frequently have morphological features that differ from those of adult stages, and many characters found later in ontogeny are not available in initial stages. Hence, morphological descriptions of early stages are useful to provide information for the identification of eggs and larvae, a knowledge still restricted among Neotropical fishes. We studied the development of Heterocharax macrolepis, a heterocharacine whose adult specimens from the aquarium trade were kept and spawned at around 23-24ºC. A developmental series of 51 specimens was preserved, ranging from 3.2 mm notochord length to 18.6 mm standard length, covering approximately the first 73 days post-hatching. We described the development of main morphological...

Provedor de dados: 83
Autores: Souza,Jordson de Souza e; Sarmento-Soares,Luisa M.; Canto,André L. Colares; Ribeiro,Frank Raynner V.
ABSTRACT Tatia comprises twenty-five valid species, distributed in the main inland watersheds of South America, including the Orinoco, Essequibo, and coastal rivers of Suriname, Amazon, upper rio Paraná and São Francisco basins. A new species is described from tributaries of upper rio Manuel Alves on uplands of Serra Geral do Tocantins plateau, Tocantins State, Brazil. It is promptly distinguished from all congeners, except Tatia britskii, due to absence of an adipose fin. It differs from T. britskii by the longer caudal peduncle length (24.1–30.5% SL, mean 25.3 vs. 20.0–22.7, mean 20.9); caudal peduncle depth (10.9–16.8 SL, mean 14.1 vs. 9.4–10.5, mean 9.8), and anterior cranial border with mesethmoid width equals its length (vs. width approximately three...

Provedor de dados: 83
Autores: Costa,Wilson J. E. M.
Rivulus kirovskyi, new species, from the central Amazon, lower rio Negro drainage, northern Brazil, is described. It is a member of an assemblage that includes R. amanapira, R. atratus, R. ornatus, R. rectocaudatus, R. romeri, R. tecminae, and R. uakti, and is diagnosed by a unique pattern of frontal squamation and a derived color pattern of the infraorbital region. Relationships of the new species with other taxa of the group are unclear at the present. It is similar to R. atratus, R. ornatus, and R. romeri in having an apomorphic reduction of anal-fin rays and by the absence of caudal spot in females, and similar to R. amanapira, R. rectocaudatus, R. romeri, R. tecminae, and R. uakti, by the absence of preopercular canal and dermosphenotic.

Provedor de dados: 83
Autores: Netto-Ferreira,André L.; Oyakawa,Osvaldo T.; Zuanon,Jansen; Nolasco,José C.
Lebiasina yepezi, a new Lebiasininae with a conspicuous color pattern, is described. The new species is endemic of the headwaters of the rio Negro, rio Branco, and rio Orinoco in the Serra Parima-Tapirapecó Mountains, at the border of Brazil and Venezuela. The new species is readily distinguished from all other Lebiasininae by the presence of four black longitudinal stripes on the trunk, and the triangular shaped dorsal surface of the mesethmoid, lacking lateral projections. The unusual color pattern is contrasted with those of other lebiasinin, as well as members of the pyrrhulinin genus Nannostomus. A close relationship between Lebiasina yepezi and the Gran Sabana (Venezuela) species is suggested based in color pattern features. The present contribution...

The recently resurrected callichthyid catfish genus Scleromystax includes species occurring in several Brazilian coastal river basins from southern Bahia to southern Santa Catarina. Several character states, especially those related to sexual dimorphism, demonstrate the monophyly of Scleromystax. Examination of Scleromystax specimens sampled from streams in the Ilha de Santa Catarina and Nova Veneza, and the rio Mampituba basin, Santa Catarina and Rio Grande do Sul States, revealed that they constitute a new taxon, and thus the southernmost record for the genus. Scleromystax salmacis, new species, has coloration similar to that of S. macropterus, differing from that species mainly by the absence of a black spot on the base of the median caudal-fin rays,...

Autores: Loureiro,Marcelo; Duarte,Alejandro; Zarucki,Matías.
A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin) and río Yaguarón (Patos-Merín system). The new species can be differentiated from all other species of the genus by the unique presence in males of uniform bluish gray pigmentation on flanks (without vertical bands) and unpaired fins. The new species is also distinguished by the combination of characters associated with a reduction of the squamation of the abdominal, preopercular, and opercular regions. The new species presents some morphological characteristics similar to A. gymnoventris and A. luteoflammulatus. The distribution of the new species is concordant with three other species of Austrolebias and may represent a case of drainage...

ABSTRACT Lutjanidae comprises 21 genera and 135 species widespread throughout Atlantic, Indian and Pacific oceans. Nonetheless, the phylogenetic relationships of Lutjaninae remain uncertain. Furthermore, phylogenetic hypotheses for Lutjanus alexandrei, an endemic species from northeastern Brazilian coast, in Lutjanidae are absent so far. Therefore, we carried out multiloci analyses, combining both mitochondrial and nuclear DNA sequences in Lutjaninae species from Western Atlantic focusing on the controversial relationships among Lutjanus, Rhomboplites, and Ocyurus. Besides, we determined the phylogenetic position and dated the origin of L. alexandrei. The phylogenetics trees based on the 4.4 kb for 11 species corroborated the synonym among Lutjanus and the...

Provedor de dados: 83
Autores: Costa,Wilson J. E. M.; Reis,Roberto E.; Behr,Everton R.
Austrolebias varzeae n. sp. is described from rio da Várzea floodplains, upper rio Uruguay basin, southern Brazil. It seems to be closely related to A. carvalhoi (Myers), with which it shares a similar color pattern of male and an apomorphic morphology of the autopalatine. The new species differs from A. carvalhoi by having more anal-fin rays in males and more caudal-fin rays. Austrolebias varzeae is distinguished from all other species of the genus by a unique color pattern, in which there are three distinctively darker and narrower bars on the anterior portion of male flank. Putative close relationships between A. varzeae and A. carvalhoi suggest a closely related biogeographic history between upper Uruguay and upper Iguaçu River basins, corroborated by...

Provedor de dados: 83
Autores: Shibatta,Oscar Akio; Vari,Richard P.
ABSTRACT Rhyacoglanis, a new genus of the South American freshwater catfish family Pseudopimelodidae is described from cis-Andean portions of the continent. Rhyacoglanis is distinguished from other genera of the family by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. Species of Rhyacoglanis are rheophilic and strongly associated with rapids and other swift-flowing waters. A phylogenetic analysis based on 41 morphological characters yields a hypothesis of monophyly of the Pseudopimelodidae and Rhyacoglanis. Pimelodus pulcher Boulenger, 1887, from the western Amazon basin is designated as type-species of the new...

Provedor de dados: 83
Autores: Reis,Roberto E.
A new, uniquely colored species of the loricariid catfish genus Otocinclus, O. cocama is described from a tributary to the lower río Ucayali in northern Peru. The new species is distinguished from other Otocinclus species by two putatively autapomorphic features, the distinct color pattern, consisting of vertically elongated blotches spanning from the dorsal midline to the ventral border of flanks, and by a complete lateral line. The phylogenetic relationships of the new species are investigated and it is apparently more closely related to a clade formed by O. huaorani, O. bororo, O. mariae, and O. mura. Comments on the impact of taxonomic revisions for the discovery and description of previously undetected biodiversity are also presented.

Jenynsia luxata, a new species from northwestern Argentina, is described. This species is diagnosable from all other Jenynsia by the medial processes of left and right pelvic bones relatively reduced and separated from each other. The new species resembles J. multidentata, but it is further distinguished from this species by the absence of a swelling between the urogenital opening and the anterior base of the anal fin in females and details of coloration. Phylogenetic analyses, both under implied and equal weighting, recover the subgenera Plesiojenynsia and Jenynsia as monophyletic units. New information on previously missing characters of Jenynsia maculata is added. These data and phylogenetic characters coded for the new species herein described...

Centromochlus comprises twelve species, distributed in the main inland watersheds of South America, including the Orinoco, Essequibo, coastal rivers of Suriname, Amazon, upper Paraná and São Francisco basins. The new species is described from the upper rio Paraná based on material collected in 1965 during the construction of the UHE Ilha Solteira, São Paulo, Brazil. The new species is easily distinguished from all congeners due to absence of adipose fin, a condition otherwise restricted to Gelanoglanis nanonocticolus, among centromochlin catfishes. The new species comprises small catfishes (adults ranging from 35 to 39 mm SL), in which modified anal fin of males is devoid of denticulations or spines, and most posterior rays reduced in length.

ABSTRACT Steindachnerina nigrotaenia is resurrected from the synonym of S. brevipinna and considered a valid species. The previous designation of the lectotype of S. nigrotaenia is considered invalid and a new lectotype is designated herein. Steindachnerina nigrotaenia and S. insculpta are redescribed based on type specimens and on additional material from the rio Paraguai and the upper rio Paraná basins, respectively. The two species can be separated by the number of scales of the lateral line and of the transverse series and by phylogenetic analyses of molecular data.

Autores: Ferrer,Juliano; Malabarba,Luiz R.; Costa,Wilson J. E. M.
Austrolebias paucisquama is described from the rio Vacacaí drainage, a tributary to the rio Jacuí, Rio Grande do Sul, Brazil. The new species belongs to the Austrolebias alexandri species-group, by sharing the apomorphic bright blue iridescence and dark gray pectoral fins in males. It is distinguished from other species of this group by having fewer scales around caudal peduncle (12) and fewer dorsal-fin rays in males (17-21). The lack of contact organs on the inner surface of the pectoral fin in males and the color pattern of females - ground color light brownish, sides of body with a variable number of relatively large dark black spots distributed mostly on posterior portion of body - distinguish A. paucisquama from all other species of the genus.

Sperm characteristics as additional evidence of close relationship between Lebiasina and Piabucina (Characiformes: Lebiasinidae: Lebiasininae)
Provedor de dados: 83
Autores: Santana,Júlio César de O.; Netto-Ferreira,André L.; Calcagnotto,Daniela; Quagio-Grassiotto,Irani.
Spermiogenesis and spermatozoa of representatives of the genera Lebiasina and Piabucinaare described. Spermiogenesis is quite similar among all analyzed species of these genera and is identified as Type II. In this type of spermiogenesis, the flagellum of earliest spermatids lies lateral to the nucleus. A slight movement of the nucleus towards the centriolar complex is observed. In late spermatids, the nucleus slightly elongates towards the flagellum. The formation of two striated rootlets apparently occurs in early/intermediate spermatids. The spermatozoa of species of Lebiasinaand Piabucina share (1) a drop-shaped slightly elongated nucleus that is laterally positioned relative to the flagellum; (2) a superolateral centriolar complex; (3) two striated...

Three new species of Lebiasina (Characiformes: Lebiasinidae) from the Brazilian shield border at Serra do Cachimbo, Pará, Brazil
Provedor de dados: 83
Autores: Netto-Ferreira,André L.
Lebiasina marilynae n. sp., L. melanoguttata n. sp., and L. minuta n. sp. are described from the headwaters of the rio Curuá, in Serra do Cachimbo, Pará, Brazil, and represent the only members of the Lebiasininae in the Brazilian Shied, so far. A close relationship among these species is proposed based on: 1) the presence of a pair of foramina through which the ramus palatinus of the facial nerve passes, a modification unique in Lebiasinidae and apparently in the Characiformes, 2) the enlargement of the extrascapular bone, 3) the absence of the secondary stripe, and 4) the nearly equal length of caudal-fin lobes.

ABSTRACT The discovery of three new taxa of Hypoptotopomatini with ambiguous generic assignment prompted a reanalysis of the phylogenetic relationships of the tribe. The analysis focused on a data matrix of 56 terminals and 107 morphological characters comprising the three new taxa, most species of Hypoptopoma and Otocinclus, and all other species of the tribe. The 162 maximally parsimonious trees of 382 steps, consistency index of 0.41, and retention index of 0.83 were then summarized in a strict consensus tree. The results confirm the monophyly of the Hypoptopomatini, recover four genera as monophyletic (Acestridium, Hypoptopoma, Niobichthys, and Otocinclus), revealed Hypoptopoma and Oxyropsis to be non-monophyletic; and revealed two new genera within...

Ituglanis cahyensis, a new catfish from Bahia, Brazil (Siluriformes: Trichomycteridae)
Provedor de dados: 83
Autores: Sarmento-Soares,Luisa M.; Martins-Pinheiro,Ronaldo F.; Aranda,Arion T.; Chamon,Carine C.
A new trichomycterid catfish of the genus Ituglanis is described from the rio Palmares, a tributary of the rio Cahy in southeast Bahia State, Brazil. Ituglanis cahyensis is distinguished from all other congeners through a combination of characters, as the supraorbital laterosensory canal branch with pores s3 and s6 present, the low count of branched pectoral fin rays, and low number of paired ribs. It is further distinguished in proportional measurements, such as elongate nasal, maxillary, and rictal barbels, and small eye diameter.

Parotocinclus arandai, a new species of hypoptopomatine catfish (Siluriformes: Loricariidae) from the upper rios Jucuruçu and Buranhém, States of Bahia and Minas Gerais, Brazil
Provedor de dados: 83
Autores: Sarmento-Soares,Luisa Maria; Lehmann A.,Pablo; Martins-Pinheiro,Ronaldo Fernando.
Parotocinclus arandai, new species of the hypoptopomatine catfish, is described from small creeks in the upper rios Jucuruçu and Buranhém basins, at the border of Brazilian States of Bahia and Minas Gerais. Parotocinclus arandai is distinguished from all congeners from the Atlantic coastal basins of southeastern and eastern Brazil, except Parotocinclus bahiensis, by having the branched rays and interradial membranes of the pectoral and pelvic fins unpigmented in ventral view. The new species is distinguished from most Parotocinclus species, by having a small eye, 14.8-19.3 mm HL (except P. maculicauda and P. planicauda) and by the presence of a tuft of hypertrophied odontodes on the supraoccipital (except P. cristatus and P. cesarpintoi).

A new Aspidoras (Siluriformes: Callichthyidae) from rio Paraguaçu basin, Chapada Diamantina, Bahia, Brazil
Provedor de dados: 83
Autores: Britto,Marcelo R.; Lima,Flávio C. T.; Santos,Alexandre C. A.
During a recent ichthyological survey in Chapada Diamantina, Estado da Bahia, Brazil, a new, very distinctive Aspidoras was discovered in tributaries of the upper rio Paraguaçu. The new taxon differs from its congeners mainly in having: a poorly-developed pigmentation pattern, restricted to minute scattered blotches on dorsal region of head and body, but grouped in small, irregular blotches along the lateral body plate junction; four or five caudal vertebra, anterior to compound caudal centrum, with neural and haemal spines placed posteriorly, close to post-zygapophyses; and post-zygapophyses of the precaudal vertebrae without dorsal expansions connected with their respective neural spines. The new species shares with Aspidoras velites dorsolateral body...

Description of males of Phallotorynus pankalos Lucinda, Rosa &amp;amp; Reis, 2005 and reappraisal of Phallotorynus species relationships (Teleostei: Cyprinodontiformes: Poeciliidae)
Provedor de dados: 83
Autores: Lucinda,Paulo H. F.; Graça,Weferson J. da.
Recently discovered male specimens of Phallotorynus pankalos are described and diagnosed from males of congener species on the basis of gonopodial morphology, color pattern and number of dorsal and anal-fin rays. The phylogenetic hypothesis of relationships among Phallotorynus species is reappraised with the inclusion of P. pankalos. Phallotorynus pankalos is hypothesized as sister to P. jucundus, a clade sister to P. victoriae or to a clade composed of P. dispilos and P. psittakos. Biogeography of Phallotorynus species is discussed, and it is suggested: (1) an early basal split between the rio Paraíba do Sul drainage and the Paraná-Paraguay system, separating P. fasciolatus from the ancestor of the remaining Phallotorynus species followed by a dispersal...

Phylogenetic relationships of the enigmatic Carlastyanax aurocaudatus (Eigenmann) with remarks on the phylogeny of the Stevardiinae (Teleostei: Characidae)
Provedor de dados: 83
Autores: Mirande,Juan Marcos; Jerep,Fernando Camargo; Vanegas-Ríos,James Anyelo.
The monotypic genus Carlastyanax Géry was defined to include Astyanax aurocaudatus, a morphologically odd species having, among other features, four teeth in the posterior premaxillary row and eight branched dorsal-fin rays. Later on, the characters used to define Carlastyanax were considered as invalid and this genus was synonymized with Astyanax. In this paper, we include Astyanax aurocaudatus in a phylogeny of the Characidae and obtain a sister-group relationship between this species and Creagrutus, within the Stevardiinae. The resurrection of Carlastyanax as a valid genus is therefore proposed. The analysis presented is the largest phylogeny of the Stevardiinae so far published. Relationships of this subfamily are also discussed.

Provedor de dados: 83
Autores: Bichuette,Maria Elina; Pinna,Mario César Cardoso de; Trajano,Eleonora.
A new species of the rare copionodontine genus Glaphyropoma is described from subterranean waters in the Diamantina Plateau, Bahia State, central northeastern Brazil. This is the first troglomorphic species in the subfamily Copionodontinae. It is distinguished from all other copionodontines by the presence of opercular odontodes, and further distinguished from its only congener, G. rodriguesi, by the reduction of dark integumentary pigmentation. The new species shares the single synapomorphy previously proposed for Glaphyropoma, the marked narrowing of the first hypobranchial and indirect character evidence also supports its inclusion in the genus. The presence of opercular odontodes in the new species, in combination with a reviewed hypothesis of sister...

The systematics and ecology of free-living marine nematodes
Provedor de dados: 27
Autores: Heip, C.H.R.; Vincx, M.; Smol, N.; Vranken, G.
Nematodes are the most abundant metazoans in marine (littoral, estuarine, coastal and oceanic) sediments, extending from the high-water mark into the deepest oceanic trenches (Nicholas, 1975). All marine free-living nematodes are considered to be members of the meiobenthos; small organisms, mainly metazoans, which are separated from the larger macrobenthos either on a methodological basis (i.e. as all animals passing a 1 mm or a 0.5 mm sieve) or a taxonomic basis (i.e. particular animal groups such as Nematoda, Harpacticoida, Gastrotricha, Kinorhyncha, Tardigrada, Foraminifera etc. which consist exclusively or mainly of small species living in sediments). In most circumstances, nematodes are numerically the dominant group of the meiofauna. In fact, they...

Autores: Menezes,Natalia; Neves,Elizabeth; Kikuchi,Ruy K.P.; Johnsson,Rodrigo.
Siderastrea is a small genus of scleractinian corals, composed by zooxanthellate massive colonial forms. Besides contributing to the consolidation of the reef structure, represent a group with significant resistance to environmental stress. Until the 70's, its taxonomy was a complicated task, limited by the difficulty in identifying morphotypes. More recently, interspecific boundaries were redefined for 'Atlantic Siderastrea Complex'. However, despite new perspectives, including the occurrence of S. radians and S. siderea for Brazil, morphological patterns are still poorly studied and inconspicuous for several coastal areas. In order to characterize levels of intraspecific and interspecific morphological variation in S. stellata and S. radians,...

Anatomical study on Myoforceps aristatus, an invasive boring bivalve in S.E. Brazilian coast (Mytilidae)
Provedor de dados: 84
Autores: Simone,Luiz Ricardo L.; Gonçalves,Eric Pedro.
The bivalve Myoforceps aristatus (Dillwyn, 1817), also known as Lithophaga aristata, have been recently collected in the coasts of Rio de Janeiro and São Paulo, Brazil; a species that bores shells of other mollusks. This occurrence has been interpreted as an invasion of this species, originally from the Caribbean. The distinguishing character of the species is the posterior extensions of the shell crossing with each other. Because specimens with this character have also been collected in the Pacific Ocean, they all have been considered a single species. However, it is possible that more than one species may be involved in such worldwide distribution. With the objective of providing full information based on Atlantic specimens, a complete anatomical...

The philosophy of total evidence and its relevance for phylogenetic inference
Provedor de dados: 84
Autores: Rieppel,Olivier.
The test of congruence under total evidence as used in systematics has been tied to a Popperian philosophy of science, but is here shown to be related to the coherence theory of truth in metaphysics and thus to coherentism in epistemology. Since the test of congruence is coherentist, the contextual (theoretical) background of initial character conceptualization cannot be ignored as is suggested by some proponents of the total evidence approach. The relative merits of a total evidence approach versus conditional data set partitioning are considered, and whereas both have their merits and drawbacks, either approach requires causal grounding of character statements (statements of homology), at least approximately and defeasibly. The conclusion is that...

Morphological analysis of Mecosarthron Buquet and Xixuthrus Thomson and Reevaluation of Generic Assignment of Xixuthrus domingoensis Fisher (Coleoptera, Cerambycidae, Prioninae)
Provedor de dados: 84
Autores: Santos-Silva,Antonio; Lingafelter,Steven W.
The characters defining Mecosarthron Buquet, 1840 and Xixuthrus Thomson 1864 are discussed, along with a historical review of the literature that described and classified these taxa. Through morphological examination of these genera and most of the included species, we addressed the systematic placement of Xixuthrus domingoensis Fisher, 1932 that was placed in Mecosarthron by Ivie (1985). We restore its placement in the genus Xixuthrus. The first description of the female of X. domingoensis is provided, along with comparative redescriptions of Mecosarthron gounellei (Lameere, 1903), and M. buphagus Buquet, 1840. We include a key to the species currently in Mecosarthron.

A new species of Chaetostoma Tschudi (Siluriformes: Loricariidae) from Colombia with a definition of the C. anale species group
Provedor de dados: 84
Autores: Ballen,Gustavo A.
Chaetostoma formosae sp. nov. is described from piedmont tributaries of the upper río Meta on the Cordillera Oriental in Colombia. The new species is distinguished from its congeners by the presence of an elongate unbranched anal-fin ray with two posterior dermal ridges in mature males, the presence of strongly recurved cheek odontodes, the presence of a parieto-supraoccipital dermal keel, the posterior margin of the pelvic-fin strongly projected and angulate in shape in mature males, and by details of coloration. The new species belongs to an informal monophyletic group herein called the Chaetostoma anale species group, along with two additional species, C. anale and C. jegui, from Colombia and Brazil respectively, based on an apomorphic modification of...

Molecular phylogeny of advanced snakes (Serpentes, Caenophidia) with an emphasis on South American Xenodontines: a revised classification and descriptions of new taxa
Provedor de dados: 84
Autores: Zaher,Hussam; Grazziotin,Felipe Gobbi; Cadle,John E.; Murphy,Robert W.; Moura-Leite,Julio Cesar de; Bonatto,Sandro L.
We present a molecular phylogenetic analysis of caenophidian (advanced) snakes using sequences from two mitochondrial genes (12S and 16S rRNA) and one nuclear (c-mos) gene (1681 total base pairs), and with 131 terminal taxa sampled from throughout all major caenophidian lineages but focussing on Neotropical xenodontines. Direct optimization parsimony analysis resulted in a well-resolved phylogenetic tree, which corroborates some clades identified in previous analyses and suggests new hypotheses for the composition and relationships of others. The major salient points of our analysis are: (1) placement of Acrochordus, Xenodermatids, and Pareatids as successive outgroups to all remaining caenophidians (including viperids, elapids, atractaspidids, and all...

What do we know about Neotropical trap-nesting bees? Synopsis about their nest biology and taxonomy
Provedor de dados: 84
Autores: Costa,Camila Cristina Ferreira da; Gonçalves,Rodrigo Barbosa.
Abstract Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from...

ADVANCES ON DIPTEROLOGY IN THE 21 ST CENTURY AND EXTINCTION RATES
Provedor de dados: 84
Autores: SANTOS,DAUBIAN; SAMPRONHA,STEPHANIE; SANTOS,CHARLES MORPHY DIAS.
ABSTRACT At least one million extant insect species have been described on Earth, of which 150,000 belong to the megadiverse order Diptera. We here synthesize data from the last 15 years of taxonomic work in Diptera, mapping the world taxonomic productivity in the order. Our data shows an increasing importance of China and Brazil in taxonomic production, along with other traditional centres such as the USA and Europe. We correlate our database with estimates of extinction rates to determine the amount of basic taxonomic research still necessary to have the description of the fly diversity before extinction. Due to the growing recent extinction rates, it is unlikely that we will be able to entirely describe unknown fly diversity before their demise. Even...

Autores: Oliveira,Letícia A. de; Inez,Tiago G.; Ferreira,Wellington D.; Hermes,Marcel G.
ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systematics have been proposed in the last five years, including the genus Alphamenes. This taxon contains seven described species whose distribution is exclusively Neotropical. Females are morphologically homogeneous, and characters related to copulatory organs are useful in male diagnosis. This contribution forms the first phylogenetic approach to include all species of Alphamenes, hence the first to strongly...

Autores: Silveira,Orlando Tobias; Santos Jr.,José Nazareno Araújo dos.
Comparative morphology of the mandibles of female polistine social wasps (Hymenoptera, Vespidae, Polistinae). Diversity of mandibular forms in female polistines is explored and compared among 116 species of all polistine genera. Inferences about function are made and discussed based on observed form differences. Mandible length and width measurements are analyzed for a subset of polistine species plus two vespines and two eumenines. A variable expressing the ratio between these variables is also considered in morphometric analyses. The following mechanical interactions among mandible structural elements are highlighted: opposition and crossing of mandibles' apical teeth at the middle of the closing trajectory; shearing action of the apical teeth against...

Phylogeny of the Augochlora clade with the description of four new species (Hymenoptera, Apoidea)
Provedor de dados: 92
Autores: Gonçalves,Rodrigo Barbosa.
ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social, except Ceratalictus for which nothing is known. Wood nesting behavior arose once in the clade, in Augochlora sensu strictu. The objective of this study is to describe four new species and to present a revised phylogenetic analysis of the Augochlora clade for the placement of these species. The morphological matrix comprised 77 characters and 42 terminals, and resulted in two most parsimonious trees....

Phylogeny of wasps of the genus Mischocyttarus de Saussure (Hymenoptera, Vespidae, Polistinae)
Provedor de dados: 92
Autores: Silveira,Orlando Tobias.
A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978).

Revolutionary thoughts on taxonomy: declarations of independence and interdependence
Provedor de dados: 103
Autores: Wheeler,Quentin D.
Credible biological research depends on accurate species identifications, reliable scientific names, and an evolutionary context provided by a phylogeny or phylogenetic classification. The emphasis on such taxonomic services has detracted from the fundamental taxonomic research necessary to create and sustain such knowledge systems. A taxonomic declaration of independence is presented, emphasizing the unique mission, goals, and needs of taxonomists and taxonomic (collection-based) institutions and the non-experimental yet scientifically rigorous epistemology of taxonomy. At the same time taxonomic interdependence is declared. Questions pursued by taxonomists are planetary in scale and can only be answered given international collaboration and coordination...

Ceraeochrysa caligata (Banks, 1945) is one of the several species of Ceraeochrysa Adams, 1982 that occur in agroecosystems of the Neotropical region and show potential for use in biological control programs. However, little is known about its biology, partly because of the poor status of the systematics of this group. To help in the identification of C. caligata and to contribute with additional characters for future phylogenetic studies with the genus, here we characterize the variations in relation to the pattern of integument markings originally described for the adults and larvae and redescribe the three larval instars, including characters not considered in the original description, especially the number of setae in the tubercles and somatic segments....

Seira Lubbock, 1869 is the most speciose genus of Collembola in Brazil. Herein, we describe and illustrate a new species of Seira, Seira ritae sp. nov., collected in João Pessoa, state of Paraíba, Brazil, in an urban seaside area. The new species shows many similarities with S. mendoncea Bellini &amp;amp; Zeppelini, 2009 especially in what concerns the dorsal distribution of the macrochaetae of the head, the metathorax, and the first three abdominal segments. However, the two species can be distinguished by the chaetotaxy of the mesothorax and abdominal segment IV. The type locality of the species probably indicates some level of natural resistance to the impacts associated with human activities.

The taxonomic status of the species in the genus Callophyllis Kützing (Kallymeniaceae, Rhodophyta) from central-south Chile (33° to 41° S) is examined on the basis of morphological and molecular evidence. Of the four species originally cited for central Chile, C. variegata, C. pinnata, C. atrosanguinea and C. laciniata, only the presence of C. variegata has been confirmed in this study. C. pinnata reported from Chile is found to be different from C. pinnata described from California, and it is here newly described as C. concepcionensis sp. nov. C. atrosanguinea from southern Chile (including C. linguata from the Antarctic Peninsula) is distinct from the species called C. atrosanguinea from central-south Chile, the latter which is here described as C....

The identity of many Neotropical species of Pseudisobrachium Kieffer, 1904 is currently unreachable, mostly because the available descriptions and illustrations are not sufficiently accurate to allow precise identifications. To help solve the problem, 115 valid species and their junior synonyms were examined. Twelve nomenclatural acts are made, and 110 valid species are recognized for the Neotropical region. Two lectotypes are designated: Pristocera crassicornis Westwood and Pristocera haemorrhoidalis Westwood. Seven new species-group synonyms are proposed: Pseudisobrachium retusum Evans syn. nov. for P. pauxillum Evans; P. cunco Perez syn. nov. for P. erythrocephalum Evans; P. navajo Evans, P. rectangulatum Evans, P. emarginatum Evans and P. foutsi Evans...

Phylogenetic relationships within Oweniidae Rioja (Polychaeta, Annelida)
Provedor de dados: 104
Autores: Sene-Silva,Gustavo.
The Oweniidae consist of five genera of tubiculous polychaetes occurring in all oceans from tropical topolarareas: Owenia Delle Chiaje, 1842, Myriochele Malmgren, 1867, Galathowenia Kirkegaard, 1959, Myriowenia Hartrnan, 1960 and Myrioglobula Hartrnan, 1967. The group is regarded as monophyletic based on the presence of dense fields of bidentate neuropodial hooks. Fourteen species were submitted to a cladistic analysis in PAUP 3.1.1 with the usage of 19 morphological characters.The taxonomic status of the ingroup taxa could be evaluated and it has been found that: (1) Owenia, Myriowenia and Myrioglobula are monophyletic, and (2) Myriochele, and Galathowenia are both paraphyletic taxa.

Autores: Hara,Marcos R.; Pinto-da-Rocha,Ricardo.
A new species of Pickeliana Mello-Leitão, 1932, P. albimaculata sp. nov., is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitão, 1932 by the presence of a large, ventro-apical pointed tubercle on femora III-IV. A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV. According to this analysis, P. albimaculata sp. nov. is sister species of P. pickeli. Additionally, we present an identification key and an update on the geographical distribution of species of this genus in northeastern...

Record of the rare Caribbean mud eel, Pythonichthys sanguineus (Heterenchelyidae, Anguilliformes), in the region of the Amazon Reef
Provedor de dados: 36
Autores: ROTUNDO,Matheus Marcos; MACHADO,Leonardo; OLIVEIRA,Claudio; SANTOS,Wagner César Rosa dos; MARCENIUK,Alexandre Pires.
ABSTRACT As they spend most of their time buried in the substrate and are not a fishery resource, heterenchelyids are seldom seen. These eels are characterized by their greatly reduced eyes, which are covered by semi-transparent skin, the absence of a pectoral fin or lateral line, and no pores on the head or body. Pythonichthys sanguineus is a particularly poorly-known species, with only eight scientific records from Cuba, Puerto Rico, Colombia, Venezuela, Guyana, and Suriname. The present study is based on six adult specimens of P. sanguineus captured by vessels of the shrimp trawling fleet along the northern Brazilian coast, in the vicinity of the Amazon Reef. We provide meristic, morphometric and DNA barcoding data. These findings provide insights into...

Autores: Weigand,Anna; Lehnert,Marcus.
ABSTRACT A synopsis of all scaly tree fern species (Cyatheaceae) occurring in Brazil is presented. We recognize 51 species in three genera [Sphaeropteris one species, Alsophila four species (one subspecies, two varieties), and Cyathea 45 species (one variety) ] with 17 taxa being endemic to Brazil. One hybrid endemic to Brazil is recognized. Further included are five species that have not yet been recorded in Brazil, but are expected here because they are found in adjacent countries and occur literally on the border with Brazil. We present the first key covering the family for the whole territory of Brazil.

The taxonomic significance of seed morphology in the Passiflora subgenus Astrophea (Passifloraceae)
Provedor de dados: 39
Autores: Mezzonato-Pires,Ana Carolina; Mendonça,Cláudia Barbieri Ferreira; Milward-De-Azevedo,Michaele Alvim; Gonçalves-Esteves,Vania.
ABSTRACT The center of diversity for Passiflora subg. Astrophea is in low altitude areas of northern South America. The majority of species of this group are difficult to find in nature. Seed morphology was described in detail for 25 species of Passiflora subgenus Astrophea, a subgenus that until now did not exist. For morphological analysis, 20 seeds per species were measured for length, width and thickness, and the arithmetic means calculated. The seeds varied in length, width and thickness. Eight types of ornamentation were found. The margins varied among crestate, dentate, parted, entire and parted-crestate. The seed apex can be distinguished by the shape and position of the apical appendage. Seed shape varied among obovate, lanceolate, cordiform, and...

Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe
Provedor de dados: 39
Autores: Chaowasku,Tanawat.
ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the second diverging lineage of Annonaceae after Anaxagorea (the only genus of Anaxagoreoideae) and as the sister group of a large clade consisting of the rest of Annonaceae. Consequently, a new subfamily, Meiocarpidioideae, is established to accommodate the enigmatic African genus Meiocarpidium. In addition, the subfamily Ambavioideae is redefined to contain two major clades formally recognized as two tribes....

ABSTRACT Hypnea pseudomusciformis was recently described from South America, and has three morphological variants: “musciformis”, “nigrescens”, and “valentiae”. Information on the biology of these variants may help to explain this species’ wide morphological variation despite the absence of genetic divergence among variants. More morphological and ecological data has accumulated on the “musciformis” variant occurring on the Brazilian coast than for the others. In this study, we described the reproductive morphology of a tropical “nigrescens” population and investigated its phenology to provide crucial biological information about this taxon, and perhaps also assist in answering questions about the systematics of H. pseudomusciformis variants. The...

Miospores and chlorococcalean algae from the Los Rastros Formation, Middle to Upper Triassic of central-western Argentina
Provedor de dados: 41
Autores: Ottone,Eduardo G.; Mancuso,Adriana C.; Resano,Magdalena.
Lacustrine strata of the Los Rastros Formation (Middle to Upper Triassic) at Río Gualo section (La Rioja province), yield a distinctive palynological assemblage of miospores and chlorococcalean algae. The miospore association is characterized by a relative abundance of corystosperm pollen grains with subordinate inaperturates, diploxylonoid disaccates, spores, monocolpates, monosaccates and striate pollen grains. The phytoplankton are mostly represented by Botryococcus but also by Plaesiodictyon , a form probably related to the Hydrodictyaceae. Geological data and variations in phytoplankton content indicate that the lacustrine system probably evolved from a stretcht of freshwater with eutrophic conditions, into a body with oligotrophic conditions through...

Mesozoic Osmundaceae petrified stems are often referred to the genera Ashicaulis Tidwell 1994 or Millerocaulis Erasmus ex Tidwell emend. Tidwell 1994, depending only on the presence or absence of leaf gaps in the xylem cylinder. However, this character is problematic for generic distinctions, since some specimens (as in the living Osmundaceae) present or lack these structures, depending on the place where the plant was cut. Furthermore, different authors have identified leaf gaps in some specimens where others reported the absence of these structures. Since this generic separation often leads to incomplete comparisons between the species, it is proposed to combine Ashicaulis Tidwell 1994 and Millerocaulis Erasmus ex Tidwell emend.

The holotype of Malvinoconularia cahuanotensis (Braniša and Vanek) (Devonian, Bolivia), the type species of the monospecific genus Malvinoconularia Babcock et al., is redescribed and refigured. M. cahuanotensis exhibits several gross morphological features that together are uniquely shared with Reticulaconularia baini (Babcock and Feldmann). In both taxa, the transverse ribs are nodose, the interspaces bear longitudinal ridges (bars or crests) that are collinear (line up) across the transverse ribs, and the longitudinal centerline (midline) of the faces is marked by a subdued ridge. Additionally, the two species may also be similar in the anatomy and external ornament of the corner sulcus. The slightly undulose geometry of the transverse ribs of M....

Autores: Griffin,Miguel; Casadío,Silvio; Parras,Ana.
The record of Turkostrea damboreneae nom. nov. and Cubitostrea primordialis n. sp. in the Maastrichtian Jagüel and Roca Formations and of Turkostrea argentina n. sp., in the Danian beds of the Roca Formation reveals that the two genera involved have a history that reaches back into the Late Cretaceous in northern Patagonia. Turkostrea damboreneae nom. nov. and Cubitostrea primordialis n. sp. are the two oldest representatives of the genera in which they belong. The two species of Turkostrea show clear affinities with other species of this genus that thrived in the Paleogene of the Northern Hemisphere. Cubitostrea primordialis n. sp. is closely allied to the previously known Paleocene species common in the region. While Turkostrea appears to have survived...

Provedor de dados: 41
Autores: Kramarz,Alejandro G.; Bond,Mariano.
Parastrapotherium Ameghino, 1895 is one of the most characteristic faunal elements of the Deseadan South American Land Mammal Age (Late Oligocene) of Patagonia, and seven species have been described for that Age. The genus was traditionally differentiated from Astrapotherium by its giant size and by having a higher number of upper and lower premolars. The revision of the dentition of Parastrapotherium revealed that this genus has only one more lower premolar than Astrapotherium. Other differential features are: lower crowned cheek teeth, cingulum absent at base of labial fold in all upper cheek teeth, upper premolars with labial fold less prominent and with broader base, crown of lower incisors proportionally more robust and buccolingually broader, lower...

Major developments in conulariid research: problems of interpretation and future perspectives
Provedor de dados: 41
Autores: Leme,Juliana de Moraes; Simões,Marcello Guimarães; Rodrigues,Sabrina Coelho; Van Iten,Heyo; Marques,Antonio Carlos.
Renewed interest in conulariids has resulted in clarification of problems in the paleobiology of this group. Discoveries of skeletal structures and specimens preserved in situ, coupled with cladistic analyses, have led to a revival of Kiderlen's (1937) hypothesis that conulariids were polypoid scyphozoans or a sister taxon of this class. Until 1979, research on conulariids centered on the description of new species and on the erection of subgroups using phenetic approaches. Few papers addressed the paleobiology and phylogenetic affinities of conulariids, and none employed cladistics. In contrast, the 1980's saw the publication of major papers on the paleoecology of conulariids, and during this decade the hypothesis that conulariids were benthic organisms...

Relationships of †Codoichthys carnavalii Santos, 1994 (Teleostei, Clupeomorpha, †Ellimmichthyiformes) from the Late Aptian of São Luís-Grajaú Basin, NE Brazil
Provedor de dados: 42
Autores: FIGUEIREDO,FRANCISCO J. DE; RIBEIRO,DOUGLAS R.M.
ABSTRACT †Codoichthys carnavalii is a clupeomorph fish only found in calcareous concretions of Codó Formation, State of Maranhão. It is known based on three specimens housed in the paleontological collection of the Museu de Ciências da Terra of Departamento Nacional da Produção Mineral, Rio de Janeiro. It was omitted in most of recent cladistic analyses about clupeomorphs. We revisited its anatomy furnishing new data and additional restorations. Furthermore we explored the relationships of †Codoichthys with the computer program TNT based on a matrix with 30 taxa and 60 unordered and unweight characters. Elops was used to root the tree. The strict consensus was obtained from three shortest trees (L=181; CI=0.387; RI=0.632). The monophyly of...

A new protodidelphid (Mammalia, Marsupialia, Didelphimorphia) from the Itaboraí Basin and its implications for the evolution of the Protodidelphidae
Provedor de dados: 42
Autores: CARNEIRO,LEONARDO M.
Abstract The Protodidelphidae was a group of marsupials that lived in Gondwana from the early to middle Eocene. Among South American faunas, the Itaboraí Basin calls attention by the presence of four genera and six species. Herein is described Bergqvistherium primigenia gen. et sp. nov., a new protodidelphid from the Itaboraí Basin - lower Eocene. This taxon differs from other protodidelphids in the smaller size, developed entocristid, less brachyo-bunoid adaptations, and entoconid more mesial than the hypoconid. These characters are recovered as plesiomorphies of the Protodidelphidae, supporting Bergqvistherium as an early-divergent lineage of this group. The Protodidelphidae fauna of the Itaboraí Basin is represented by less specialized “basal” taxa,...

Bioacoustic investigations and taxonomic considerations on the Cicadetta montana species complex (Homoptera: Cicadoidea: Tibicinidae)
Provedor de dados: 42
Autores: Gogala,Matija; Trilar,Tomi.
Recent bioacoustic investigations have shown that Cicadetta montana Scopoli 1772 is a complex of morphologically similar sister species that are best characterized by their song patterns. At the type locality of C. montana, only mountain cicadas with simple, long lasting song phrases were heard, recorded and collected. Therefore, we have good reasons to suggest that this type of song is characteristic for C. montana s. str. Boulard described a song of C. montana from France with phrases composed of a long and a short echeme; this type of song is characteristic for cicadas morphologically corresponding to C. montana var. brevipennis Fieber 1876; we suggest to raise this taxon to species level. On the basis of specific song, Puissant and Boulard described C....

Reassessment and Relationships of †Scutatuspinosus itapagipensis (Teleostei, Clupeomorpha, †Ellimmichthyiformes) from the Neocomian of Recôncavo Basin, Northeastern Brazil
Provedor de dados: 42
Autores: FIGUEIREDO,FRANCISCO J. DE; RIBEIRO,DOUGLAS R.M.
ABSTRACT Clupeomorphs are found in many assemblages of the northeastern Brazil, whose ages range from the Neocomian to Paleogene. Ten species were described. Among them †Scutatuspinosus itapagipensis, a torpedo-like fish found in shales of the Marfim Formation from Bahia, remains poorly known. At first it was positioned within †Scutatuspinosinae and indicated as closely related to †Diplomystus. Diagnoses for the subfamily and genus were based on certain characters masking relationships. Recently it was placed in †Ellimmichthyiformes, but its systematic position remains controversial. We furnish additional data and restorations together with a parsimony analysis with TNT program, using 60 unordered and unweighted characters from selected species of 13...

Naming structures and qualifying properties of anuran bioacoustical signals: a call for a homology-based nomenclature and equality for quantitative data
Provedor de dados: 42
Autores: HEPP,FÁBIO; POMBAL JR,JOSÉ P.
Abstract: There is a significant interest for using call features in taxonomic and systematic studies. However, the indiscriminate use of alternative terms for the acoustic structures has precluded reliable comparisons among species without directly checking recordings of all compared species. Recent attempts of nomenclature standardization have focused on term and structure definitions instead of homology. Here, we argue that application of nomenclatural propositions based on universal similarities is pragmatically difficult (likely impossible) and, most importantly, inaccurate regarding to assessment of homology. If homology is not properly assessed, nomenclature can lead to artificial groupings, which can hamper our understanding of the natural world....

Insect taxonomy in species-rich countries: the way forward?
Provedor de dados: 44
Autores: Mound,Laurence A.
There are two extremes in taxonomic behavior - publishing quickly as new taxa become available, and waiting a lifetime in the hope of publishing results that cannot be faulted. Neither of these extremes meets the needs of contemporary biologists in furthering our understanding of the evolution and maintenance of biological diversity. Part of the reason for these extremes is our failure to define suitable objectives for taxonomy. Instead of emphasising the units of biological diversity, we should concentrate on investigating patterns, structural, biological, ecological, temporal, and geographical, because it is these patterns that will generate novel ideas about the evolutionary history of organisms, and that will be most likely to be of interest to the...

Intracolonial variation in Siderastrea de Blainville, 1830 (Anthozoa, Scleractinia): taxonomy under challenging morphological constraints
Provedor de dados: 49
Autores: Menezes,Natália Matos de; Neves,Elizabeth Gerardo; Barros,Francisco; Kikuchi,Ruy Kenji Papa de; Johnsson,Rodrigo.
The morphology of sessile invertebrates, such as scleractinian corals, can be controlled by environmental and genetic mechanisms and, consequently, it is highly variable. Morphological variation has puzzled taxonomists by posing challenges to species classification within cryptic species complexes. The 'Atlantic Siderastrea Complex' is a suitable example. Because of overlapping diagnostic traits, the morphological interspecific limits of this group remain controversial and often resulted in doubtful synonyms. In addition, the recent identification of the Caribbean S. radians in the Southwestern Atlantic has revealed that intraspecific variation has been equivocally assessed. Traditionally, hierarchical categories of variation have been the criteria used to...

Range extension of the mud crab Eurypanopeus depressus (Smith, 1869) (Decapoda, Panopeidae): A new record for the coastal south of Brazil
Provedor de dados: 49
Autores: Rodrigues,Marcos A.; Vieira,Rony R.R.; D'Incao,Fernando.
The discovery of Eurypanopeus depressus (Decapoda: Panopeidae; Smith, 1869) on the coast of Rio Grande do Sul, Brazil suggests that the species was recently introduced, possibly due to different sources of introduction, such as the ballast water of ships. E. depressus were collected using otter-trawl net in the Patos Lagoon Estuary. Discussion focuses on the fact that the primary South American distribution derives from Uruguayan shores, and later expanded to nearby places (Brazil and Argentina). This work extends the Southern Hemisphere distribution for the species, as it was previously reported only from Argentina to Uruguay.
