Disentangling the Trichoderma viridescens complex Naturalis
Jaklitsch, W.M.; Samuels, G.J.; Ismaiel, A.; Voglmayr, H..
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....

Distribution and morphometrics of Natalus stramineus from South America (Chiroptera, Natalidae) Iheringia, Sér. Zool.
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....

Diversity of gall-forming rusts (Uromycladium, Pucciniales) on Acacia in Australia Naturalis
Doungsa-ard, C.; McTaggart, A.R.; Geering, A.D.W.; Shivas, R.G..
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 & Maslin (1992). An epitype of U. tepperianum on A. ligulata is...

Elucidating the Ramularia eucalypti species complex Naturalis
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...

Eocene crabs (Crustacea, Brachyura) from Bonaire, Netherlands Antilles Naturalis
Collins, J.H.S.; Donovan, S.K..
Recently discovered crabs from the Middle to Upper Eocene of northern Bonaire, Netherlands Antilles, include well-preserved carapaces of Montezumella rutteni Van Straelen, originally described from an incomplete holotype. The more comprehensive description of this species provided herein includes documentation of the first attributable left cheliped of Montezumella. From the same locality, Ocalina sublevis sp. nov. considerably extends the known geographic range of this genus. Both of these Tethyan decapod genera apparently migrated west from the Mediterranean region during the Eocene. Despite these new determinations, decapod crustaceans remain poorly known from the Eocene of the Antillean islands. Additionally, Callianassa pustulosa Withers from the...

Eudendrium pocaruquarum n. sp. (Hydrozoa, Eudendriidae) from the southeastern coast of Brazil, with remarks on taxonomic approaches to the family Eudendriidae Naturalis
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.

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 Mastozool. neotrop.
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.

Exploring fungal mega-diversity: Pseudocercospora from Brazil Naturalis
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...

Finding the missing link: resolving the Coryneliomycetidae within Eurotiomycetes Naturalis
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....

Five new species of the family Ceramonematidae (Nematoda: order Chromadorida) from South Africa OMA
Furstenberg, J.P.; Vincx, M..
Three new Ceramonema species, one new Dasynemoides species and one new Pterygonema species are described from South Africa. Ceramonema algoensis sp. nov. is characterised by more than 300 annules and the elongated cephalic capsule with an elevated lip region; C. africana sp. nov. by an elongated cloacal annule and a long cephalic capsule; and C. kromensis sp. nov. by the absence of vascuolisation and a relatively short cephalic capsule. Dasynemoides tenuis sp. nov. can be distinguished from all other known species of the genus by its slender body (a=118) and the large number of body annules (690). Pterygonema papenkuili sp. nov. is characterised by the shape of the spicules, which have a spine-like structure, and a large and rectangular gubernaculum.

Foliicolous microfungi occurring on Encephalartos Naturalis
Crous, PW.; Wood, A.R.; Okada, G.; Groenewald, J.Z..
Species of Encephalartos, commonly known as bread trees, bread palms or cycads are native to Africa; the genus encompasses more than 60 species and represents an important component of the indigenous African, flora. Recently, a leaf blight disease was noted on several E. altensteinii plants growing at the foot of Table Mountain, in the Kirstenbosch Botanical Gardens of South Africa. Preliminary isolations from dead and dying leaves of E. altensteinii,, E. lebomboensis and E. princeps, collected from South Africa, revealed the presence of several novel, microfungi on this host. Novelties include Phaeomoniella capensis, Saccharata kirstenboschensis, Teratosphaeria, altensteinii and T. encephalarti. New host records of species previously only known to occur...

Fossil brachiopods from the Pleistocene of the Antilles Naturalis
Harper, D.A.T.; Donovan, S.K..
Pleistocene brachiopods are poorly known from the Antillean region, but are locally common in forereef deposits of Jamaica (lower Pleistocene Manchioneal Formation) and Barbados (Coral Rock). Of the four species known, two are new. Lacazella sp. cf. L. caribbeanensis Cooper, an encrusting thecideidean, is known from only three valves. Other species are terebratulides. Tichosina inconstanta sp. nov. is a large, ventribiconvex Tichosina species of elongate oval to tear-drop shaped outline, variably uniplicate with a pedicle foramen of moderate diameter. It differs from the similar Tichosina? bartletti (Dall) in having a larger pedicle foramen and a less-marked plication. Argyrotheca barrettiana (Davidson) is a medium to large, usually transverse Argyrotheca...

Four new species of Cosmetus from Panama, with comments on the systematics of the genus (Opiliones: Cosmetidae) Rev. Bras. Zool.
Coronato-Ribeiro,Amanda; Pinto-da-Rocha,Ricardo.
ABSTRACT Four new sympatric species of Cosmetus Perty, 1833 are described from "Reserva Natural Privada Burbayar, Provinciar Panamá, Panamá" (male holotypes deposited in MIUP). Cosmetus balboa sp. nov. can be distinguished by the combinations of following features: smooth ocularium, larger distal tubercle on pedipalpal femur, coxa I with large ventral tubercle directed upwards, coxa IV with one large dorsoproximal tubercle, two geminate (from base) dorsoapical tubercles with blunt apex. Cosmetus burbayar sp. nov., can be distinguished from other species of the genus by the irregular and discontinuous shape of its yellow spot, extending from lateral anterior to posterior margins and invading prosoma, areas I-III and free tergites. Cosmetus pollera sp. nov....
