Two new species of Pseudopimelodus Bleeker, 1858 (Siluriformes: Pseudopimelodidae) from the Magdalena Basin, Colombia

A phylogenetic analysis using a fragment of the Cytochrome C Oxidase subunit 1 gene (COI) and analyzed osteological and traditional morphometric characters provided strong support for two clades phylogenetically related to Pseudopimelodus, that showed clear-cut molecular, osteological, and morphometric differences from previously described bumblebee catfishes.

A taxonomic revision of the Neotropical electric fish genus Brachyhypopomus (Ostariophysi: Gymnotiformes: Hypopomidae), with descriptions of 15 new species

15 new species are described, and redescriptions of all 13 previously described species are provided, based on meristic, morphometric, and other morphological characters, of Brachyhypopomus, which is abundant in shallow lentic and slow-flowing freshwater habitats from southern Costa Rica and northern Venezuela to Uruguay and northern Argentina.

Revision of Tympanopleura Eigenmann (Siluriformes: Auchenipteridae) with description of two new species

The Neotropical catfish genus Tympanopleura, previously synonymized within Ageneiosus, is revalidated and included species are reviewed. Six species are recognized, two of which are described as new.

The South American Electric Glass Knifefish Genus Distocyclus (Gymnotiformes: Sternopygidae): Redefinition and Revision

Electric glass knifefishes of the genus Distocyclus, family Sternopygidae, are reviewed and the type species, D. conirostris, is found to lack the derived features present in the type-species and instead shares derived features with Archolaemus, Eigenmannia, and/or Japigny; however, the relationships of Distocycles goajira among those genera cannot be resolved.

Andinoacara blombergi, a new species from the río Esmeraldas basin in Ecuador and a review of A. rivulatus (Teleostei: Cichlidae)

Andinoacara blombergi, new species, is described from the rio Esmeraldas basin in northern Ecuador and distinguished from the most similar species, A. rivulatus, by 25 vs. 24 scal ...

Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types

A checklist of Recent and fossil catfishes (Order Siluriformes) is presented, summarizing taxonomic literature published through 2005, and one new name is proposed herein: Clariallabes teugelsi, as a replacement for Clarias (Allabenchelys) dumerili longibarbis David & Poll, 1937.

Taxonomic revision and phylogenetic relationships of Dasyloricaria Isbrücker & Nijssen, 1979 (Siluriformes: Loricariidae), with description of a new species

A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new

Revision of The Deep-channel Electric Fish Genus Sternarchogiton (Gymnotiformes: Apteronotidae)

Two new deep-channel taxa from the lowland portions of the Amazon basin are described: S. labiatus and S. preto, both of which are revised on the basis of morphology and pigmentation.

Taxonomic revision of the South American fish genus Chalceus Cuvier (Teleostei: Ostariophysi: Characiformes) with the description of three new species

The Neotropical characid fishes of the genus Chalceus Cuvier, 1817, are reviewed and characters pertaining to the monophyly of ChalCEus are discussed and a key to species is presented.
