A phylogenetic analysis of Brycon and Henochilus (Characiformes, Characidae, Bryconinae) based on the mitochondrial gene 16S rRNA
Provedor de dados: 74
Autores: Hilsdorf,Silva; Oliveira,Claudio; Lima,Flávio César Thadeo de; Matsumoto,Cristianne Kayoko.
The genus Brycon, the largest subunit of the Bryconinae, has 42 valid species distributed from southern Mexico to the La Plata River in Argentina. Henochilus is a monotypic genus, comprising a single species (H. wheatlandii) found in the upper Rio Doce basin. In the present study, partial sequences of the mitochondrial gene 16S were obtained for fifteen species of Brycon and for Henochilus wheatlandii. The results showed that the genus Brycon is paraphyletic, since Henochilus is the sister-group of B. ferox and B. insignis. The most basal species analyzed were the trans-Andean species B. henni, B. petrosus, and B. chagrensis.

Genetic variability of Hypostomus (Teleostei, Loricariidae) from the Ribeirão Maringá, a stream of the upper Rio Paraná basin, Brazil
Provedor de dados: 74
Autores: Paiva,Suzana de; Renesto,Erasmo; Zawadzki,Cláudio Henrique.
Hypostomus strigaticeps and two morphotypes of Hypostomus were collected from Ribeirão Maringá, a small tributary of the Rio Pirapó, an effluent of the upper Rio Paraná. The three populations were analyzed by allozyme electrophoresis that allowed the scoring of 25 loci from 14 enzyme systems. Heterozygosity values (He) were 0.028 in H. strigaticeps, 0.027 in Hypostomus sp. 1 and zero in Hypostomus sp. 2. Several diagnostic loci and fixed differences were observed for each population at loci Acp-A, Gcdh-A and Mdhp-A. Thus, all populations were genetically distinct, although there were many common alleles. The unbiased genetic identities of Nei (I) were estimated as 0.780 for Hypostomus sp. 1 and H. strigaticeps, 0.357 for H. strigaticeps and Hypostomus sp....

Autores: Álvarez Sierra, M.A.; García Paredes, I.; Hoek Ostende, L.W. van den; Meulen, A.J. van der; Peláez-Campomanes, P.; Sevilla, P.
The micromammal fauna from the Middle Miocene (Middle Aragonian) of La Retama, eastern central Spain, is described. It is a relatively poor rodent fauna composed by ten species only, associated to a highly diverse bat fauna, which includes five genera. The insectivores are represented by two species. This fossil assemblage has been correlated to zone Db (MN 5). The palaeoenvironmental reconstruction based on micromammals indicates open and dry conditions for this locality.    Se describen los micromamíferos del Mioceno medio (Aragoniense medio) de La Retama, sector centro-oriental español. La fauna de roedores es relativamente pobre y está compuesta únicamente por diez especies. Sin embargo, cabe destacar la elevada diversidad de los quirópteros,...

New species of Moenkhausia Eigenmann, 1903 (Characiformes: Characidae) with comments on the Moenkhausia oligolepis species complex
Provedor de dados: 83
Autores: Benine,Ricardo C.; Mariguela,Tatiane C.; Oliveira,Claudio.
A new species of Moenkhausia is described from tributaries of the rio Paraguay, Brazil. The new species is diagnosed from congeners by characters related to body coloration, the number of lateral line scales, the degree of poring of the lateral line, and number of scales rows above and below the lateral line. Molecular analyses using partial sequences of the mitochondrial gene Cytochrome Oxidase I from specimens of the new species and specimens belonging to morphologically similar species demonstrated that the new species is easily differentiated by their high genetic distance and by their position in the phylogenetic hypothesis obtained through the Maximum Parsimony methodology. The analyses of three samples of M. oligolepis also revealed that they have...

Saving our science from ourselves: the plight of biological classification
Provedor de dados: 92
Autores: Ebach,Malte C.; Carvalho,Marcelo R. de; Nihei,Silvio S.
Saving our science from ourselves: the plight of biological classification. Biological classification ( nomenclature, taxonomy, and systematics) is being sold short. The desire for new technologies, faster and cheaper taxonomic descriptions, identifications, and revisions is symptomatic of a lack of appreciation and understanding of classification. The problem of gadget-driven science, a lack of best practice and the inability to accept classification as a descriptive and empirical science are discussed. The worst cases scenario is a future in which classifications are purely artificial and uninformative.

The small species of Belostoma Latreille (Heteroptera, Belostomatidae). III. A revision of oxyurum group, with a new species from Brazil and description of the male of B. noualhieri Montandon
Provedor de dados: 92
Autores: Ribeiro,José Ricardo I.; Estévez,Ana L.
Species of the oxyurum group (sensu Lauck) consist of five extant Neotropical small species, whose lengths range 15.0 to 20.0 mm. The anterior interocular width about 1.5 times the width of an eye and ventral diverticulum of phallus flattened, circular, and large are, in combination, diagnostic. The small species of the oxyurum group were included in the Lauck´s key to the identification of the species groups, without dealing with the species included in it because many of them are very similar in appearance. Therefore here we redescribe and key the Belostoma species of the oxyurum group. Belostoma oxyurum (Dufour) is newly recorded from Brazil (Paraná and Rio Grande do Sul). Holotype and lectotype are designated for B. oxyurum and B. sanctulum Montandon,...

Provedor de dados: 103
Autores: Silva,Marília Pessoa; Hara,Marcos Ryotaro; Pinto-da-Rocha,Ricardo.
Fonckia Roewer, 1913 is revised and two new species are described in it: Fonckia contulmo sp. nov., from Monumento Nacional Contulmo, Araucanía, Chile, diagnosed mainly by the enlarged tubercles on the lateral margins of the dorsal scutum, between the median region of scutal area II and the posterior margin of the scutal area III; and Fonckia sosia sp. nov., from Parque Nacional Conguillio, Malleco, Chile, distinguished mainly by the absence of a dorso-basal apophysis on femur IV of the male and a spiniform, enlarged retroapical tubercle on tibia IV of the male. We propose the generic synonymy of Diconospelta Canals, 1934 under Fonckia Roewer, 1913, and the specific synonymy of D. vazferreirae Mello-Leitão, 1946 under F. processigera (Sørensen, 1902). We...

New records of Parvalona parva (Crustacea: Anomopoda: Chydoridae) from Brazil, with first description of the male
Provedor de dados: 103
Autores: Elmoor-Loureiro,Lourdes M.A.; Santos-Wisniewski,Maria J. dos; Rocha,Odete.
The Neotropical species Parvalona parva (Daday, 1905) was previously reported only from two localities (Northern Argentina and Lençóis Maranhenses, Brazil). In the present paper, seven new records of P. parva from Brazil are presented. The specimens were collected from small waterbodies located in the Federal District and the states of São Paulo, Pará, and Pernambuco. These new records suggest that this species is not as rare as previously believed. The male, sexual female, and the lateral head pores of parthenogenetic females are described and illustrated for the first time.

Taxonomic revision of Parampheres (Arachnida: Opiliones: Gonyleptidae)
Provedor de dados: 103
Autores: Mori,Bruno Jacob; Pinto-da-Rocha,Ricardo.
Parampheres Roewer, 1913 is a relatively common genus of South American harvestmen. This genus is easily diagnosed by the remarkable yellow patches on the prosoma. Nonetheless, species determination within this group is challenging due the convoluted taxonomic history of the group and lack of a recent revision. In this study we revise Parampheres and describe a new species, Parampheres tenebris sp. nov., from Parque Nacional da Serra Geral, Rio Grande do Sul, Brazil. The new species can be distinguished from the other species of the genus by having dorsal scutum dark, and apophysis of coxa IV of male elongated. Furthermore, we propose the following new synonymies: Callampheres boliviensis Roewer, 1913, Pertyana ronae Mello-Leitão, 1927 and Parampheres...

Description of the last instar larva of Tachysphex inconspicuus (Kirby) (Hymenoptera, Crabronidae) from Brazil
Provedor de dados: 104
Autores: Buys,Sandor C.
The last instar larva of Tachysphex inconspicuus (Kirby, 1890) is described and illustrated. Minute spines on the anterior dorsal annulets of abdominal segments and different types of setae on prothorax and mesothorax are remarkable features observed in the larva of T. inconspicuus which were not reported in previously descriptions of larvae of the genus. Distribution of spines and sensilla on the epipharynx and distribution of setae on head and body seem also useful to distinguish Tachysphex larvae.

Proposta de classificação da família Xanthidae (Crustacea, Decapoda, Brachyura) através da taxonomia numérica
Provedor de dados: 104
Autores: Coelho,Petrônio Alves; Coelho Filho,Petrônio Alves.
Several families were added in the past in order to constitute the Xanthidae, but the boundaries between Xanthidae, Parthenopidae and Goneplacidae were diluted, and the classification of some genera doubtful. By this reason was made the analysis of a typical genus of each subfamily occurring in Brazil. 50 characters were selected and coded as (0) for absence and (1) for presence. The data matrix was analysed by computer programs NTSYS and NMIX. The phenetic analysis shows the Xanthidae as a good family, but the cladistic one (Wagner tree) split them in four families: Carpiliidae, Xanthidae (with the subfamilies Menippinae, Platyxanthinae, Xanthinae and Eucratopsinae), Eriphiidae and Pilumnidae (with the subfamilies Trapeziinae and Pilumninae)....

The phylogenetic relationships of genera and families of Aplousobranchia Lahille (Tunicata, Ascidiacea) is reconstructed based on morphological characters - the first comprehensive morphology-based phylogenetic analysis for the Aplousobranchia. Monophyly of Aplousobranchia and its families were tested with samples of 14 families. The final character matrix comprised 47 characters and 41 genera as terminal taxa. Nine equally most parsimonious trees (length 161, CI = 0.5031, RI = 0.7922) were found. Characters describing replication, colony system formation, and branchial walls were the more important in phylogenetic reconstruction. These characters were more useful than others more traditionally used in ascidian taxonomy, such as: body division, position of...

Provedor de dados: 104
Autores: Buys,Sandor Christiano.
The last larval instar and the cocoon of Trypoxylon (Trypoxylon) maidli Richards, 1934 are described. This larva is apparently indistinguishable from that of T. clavicerum exiguum Tsuneki, 1956. They can be distinguished from larvae of other species in the subgenus by the following features: integument of body smooth, sensilla on both sensorial area and labrum, and distinct parietal bands. Notes on nesting site and preys from one nest are presented. Eurycoma insigne (Millidge, 1991) (Linyphiidae) and Argiope argentata (Fabricius, 1775) (Araneidae) are reported as preys.

Abstract  Fleas of Argentina are receiving renewed systematic interest, but the identification of many species associated with small mammals can be problematic. We review the taxonomy of the flea genus Agastopsylla including the re-description of two species and one subspecies, and designate neotype and neallotype for Agastopsylla hirsutior, neotype for Agastopsylla nylota nylota from the “Colección Mamíferos Lillo Anexos” (CMLA), Universidad Nacional de Tucumán, Argentina, and neotype and neallotype for Agastopsylla pearsoni from the Natural History Museum (London, U.K.). Additionally, a key to identification of the species of Agastopsylla and a distribution map of the species of the genus are included.

Autores: Pedroso-de-Moraes,Cristiano; Souza-Leal,Thiago de; Brescansin,Rafael L.; Pettini-Benelli,Adarilda; Sajo,Maria das Graças.
Considering that the root structure of the Brazilian genera belonging to the Catasetinae subtribe is poorly known, we describe the roots of twelve representatives from this subtribe. For anatomical analysis, the roots were fixed in FAA 50, preserved in ethanol 70% and sectioned at its medium region using razor blades. The sections were stained with 0.05% astra blue and safranin and mounted in glycerin. For the identification of starch we used Lugol's solution; for lignin, floroglucin chloridric; for lipids, Sudan III, and for flavanoids, potassium hydroxide. The relevant aspects were registered using a digital camera joined with an Olympus microspope (BX51 model). The structural similarities of all roots support the placement of the subtribe Catasetinae...

Abstract: Here we examine the taxonomic diversity of the Brazilian Apioninae (Coleoptera: Brentidae) and provide an update based on the literature and through examination of material in primary Brazilian collections. Ten genera and 89 species are valid and we include 30 (25 genera, 5 species) new distribution records. Chrysapion Kissinger, 1968 is first reported in Brazil, restricted to the northeast. Ranges now include the Amazon (three genera and one subgenus) and Atlantic (four genera and one subgenus) forests, the Pantanal (five genera) and Cerrado (three genera). The ranges of several genera now include more than one new biome. An identification key (including images of adults and illustrations of male genitalia) also includes the 10 Brazilian genera...

ABSTRACT: The present research updates the systematic position and nomenclature of Lepidoptera associated with soybean crops in Argentina, Brazil, Chile and Uruguay. Scientific literature lists 69 species of Lepidoptera feeding on soybean plants. These species are representatives of the Superfamilies Noctuoidea (31), Pyraloidea (13), Hesperioidea (12), Tortricoidea (5), Geometroidea (5), and Bombycoidea (3). Diversity of Lepidoptera associated to crop, injury in different parts of the plant, and changes in species composition are discussed considering the changes in plant disease management, introduction of plants expressing Bt proteins, and the recent introduction of Helicoverpa armigera (Hübner) as a new crop pest.
