A new species of the oligotrophic genus ochroconis (Sympoventuriaceae)

Ochroconis globalis, a novel species of the melanized genus Ochroconis (Sympoventuriaceae, Venturiales), is described and illustrated and distinguished phenotypically and molecularly from existing ochroconis-like species. Phylogenetic analyses using nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU) and coding gene fragments (ACT1, BT2, TEF1) revealed clustering of all strains as a monophyletic clade which was well separated from known Ochroconis species. Most strains of the new species were obtained from human-made environments, while the natural habitat of the species remains enigmatic. The new combination Ochroconis musae is introduced for one of the most commonly encountered Ochroconis species, and a phenotypic key to all species is provided.

A new species of Cnodalomyia Hull, 1962 (Diptera, Asilidae, Asilinae) from Brazil

The robber fly genus Cnodalomyia Hull, 1962 is a monotypic member of the Asilinae. The type species, C. obtusa Hull, is endemic to Itatiaia, State of Rio de Janeiro, Brazil. A new species, Cnodalomyia catarinensis sp. nov. from southern states of Brazil (Santa Catarina, Parana and Sao Paulo) is herein described and illustrated. Both species are restricted to highland areas of the Atlantic Forest. An identification key to the species is also presented.

Revision of the Neotropical robber fly genus Cnodalomyia Hull (Diptera, Asilidae, Asilinae) with description of two new species from Brazil

The genus Cnodalomyia includes only two Brazilian species: C. obtusa Hull, 1962 and C. catarinensis Lamas and Mellinger, 2008. Studying material deposited in the Museu de Zoologia da Universidade de Sao Paulo (MZUSP), the authors found a long series of unidentified specimens of the genus, some of which are specimens of C. obtusa labelled with the same data as the type series as well as other specimens from different localities, representing an enlargement of the known geographic records of the species. This material, together with the types of C. catarinensis, enables this revision. A redescription of the genus and of its type species, C. obtusa, including descriptions and illustrations of its spermathecae and egg, until now never described, the description and illustration of two new species (C. artigasi sp. nov. and C. papaveroi sp. nov.), the diagnosis and egg description of C. catarinensis and an identification key to all included species are presented herein.

Revision of the Neotropical genus Carrerapyrgota Aczel (Diptera, Pyrgotidae) with the description of two new species

The Neotropical genus Carrerapyrgota Aczel is restricted to the South America (Brazil and Argentina). The genus is composed of two previously described species, which are revised herein: C. miliaria Aczel and C. personata (Lutz & Lima). Two new Brazilian species are described: C. aczeli from Sao Paulo and C. bernardii from Bahia. Illustrations of the external morphology of adults and male and female terminalia are also included. An identification key to the species is presented, as well as a brief discussion of the biology and distribution of the genus.

A NEW SPECIES OF CATHOROPS (SILURIFORMES; ARIIDAE) FROM MESOAMERICA, WITH REDESCRIPTION OF FOUR SPECIES FROM THE EASTERN PACIFIC

The great similarities in the external morphologies and the lack of knowledge on ontogenetic and intersexual differences of species in the ariid genus Cathorops Jordan and Gilbert, 1882, has led to an abundance of misidentifications, causing great nomenclatural instability. Accordingly, the taxonomic statuses of the Cathorops species described from Eastern Pacific have remained controversial in the literature, even in recent studies. Here, we describe Cathorops raredonae, a new species from Mesoamerica (Mexico to El Salvador) and redescribe (in Cathorops) Tachysurus liropus Bristol, 1897, and Arius taylori Hildebrand, 1925, often listed as junior synonyms of Cathorops fuerthii (Steindachner, 1877) and Cathorops steindachneri (Gilbert and Starks, 1904), respectively, or treated as species inquirendae in Cathorops. We also redescribe and redefine the circumscriptions of C. fuerthii and C. steindachneri. Finally, we summarize current statuses of nominal species of Cathorops from the Eastern Pacific and provide an artificial key to identify the valid Pacific species.

Taxonomic revision of extant Doras Lacepede, 1803 (Siluriformes: Doradidae) with descriptions of three new species

Extant Doras are newly diagnosed among Doradidae by the unique combination of maxillary barbels long and fimbriate; mesethmoid with anterior lateral margins converging towards narrow tip; single anterior cranial fontanel contained largely within frontals and anteriorly by mesethmoid (posterior cranial fontanel occluded); anterior nuchal plate wide, pentaganol or roughly hexagonal, sharing distinct lateral suture with epioccipital and isolating supraoccipital from middle nuchal plate; nuchal foramina absent; coracoid process short, posterior tip falling well short of that of postcleithral process; dentary with acicular teeth; and skin immediately ventral to postcleithral process perforated with conspicuous pores. One fossil species, dagger D. dioneae, and two nominal extant species, D. carinatus and D. micropoeus, are recognized as valid and the latter two redescribed. Three additional extant species, D. phlyzakion, D. higuchii and D. zuanoni, are newly described from the middle Amazon and tributaries, lower Amazon tributaries and rio Araguaia (Tocantins drainage), respectively. Doras phlyzakion and D. zuanoni form a monophyletic group that is found in lowland, lentic habitats, and is characterized by multiple conspicuous pores in skin on breast and abdomen, a trait unique among doradids and rare if not unique among all catfishes. The remaining extant species, D. carinatus, D. higuchii and D. micropoeus, with uncertain relationships, are found in upland, lotic habitats. The occurrence of D. carinatus in the Orinoco basin suggests a historical link between right-bank tributaries of the lower Orinoco (e.g., Caroni) draining the western Guiana Shield and more eastern rivers (e.g., Cuyuni-Essequibo) that drain the Shield directly into the Atlantic Ocean. A key to extant species is provided, a neotype is designated for Silurtis carinatus Linnaeus 1766, and Mormyropsis Miranda Ribeiro, 1911, is placed in the synonymy of Doras Lacepede, 1803.

New species of Triplonychus Candeze and Globothorax Fleutiaux from Brazil (Coleoptera, Elateridae, Cardiophorinae)

Three new species of Triplonychus Candeze, T. cruspinosus sp. nov., T. crassifemoris sp. nov. and T. tibialatus sp. nov., and a new species of Globothorax Fleutiaux, G. latidens sp. nov., from Brazil are described. Illustrations, photographic and SEM images are presented. A review of the diagnostic generic characters and a key to the species of Triplonychus and Globothorax from Brazil are also given.

New species of Rhinotragini and redescription of two species of Stultutragus Clarke (Coleoptera, Cerambycidae, Cerambycinae)

Agaone amazonica sp. nov. and Stultutragus endoluteus sp. nov. are described from Brazil, and variation in A. peruviensis Fisher, is discussed. Stultutragus nigricornis is elevated to species rank and re-described. Updated keys to Agaone and Stultutragus are provided.

Two new species of Mezilaurus (Lauraceae) from Brazil

Ongoing taxonomic work on Mezilaurus has revealed two new species of the genus in Brazil, which are here described and illustrated. The first one, Mezilaurus glabriantha, from the state of Espirito Santo, represents the third endemic species known from the Brazilian Atlantic Forest, and Mezilaurus microphylla occurs in seasonally dry forests from the central Brazilian state of Tocantins. A key to distinguish the extra-Amazonian species of Mezilaurus from Brazil is provided.

Matayba obovata, a new species of Matayba sect. Matayba (Sapindaceae) from Brazil

The new species, Matayba obovata (Sapindaceae), from southern and southeastern Brazil is described, illustrated, and contrasted to its putatively closest relatives. Palynological characters are also described. The new species belongs to sect. Matayba. A key to identify M. obovata and related species in the Atlantic Forest is included.

A new species of Paralychnophora (Asteraceae: Vernonieae), and comments on the identity of Paralychnophora bicolor

The type of Paralychnophora bicolor was found to represent another species recently described as P. santosii. The misapplication of the name P. bicolor is reviewed. Also, a new species is here proposed, P. glaziouana, for plants previously identified as P. bicolor, since the only available name, P. schwackei, is an illegitimate combination. A key to Paralychnophora is given.

New Neotropical cunaxine species (Acari: Prostigmata: Cunaxidae)

Four new Brazilian cunaxine species, namely Armascirus brasiliensis Den Heyer sp. nov., A. bahiaensis Den Heyer sp. nov., Dactyloscirus saopauloensis Den Heyer sp. nov. and Riscus austroamericanus Den Heyer sp. nov. are described and figured. A key to the new species, as well as the known species of Riscus, is provided.
