• Abstract

  Loricariidae is the largest family of the order Siluriformes in the world. The subfamilies Hypoptopomatinae and Neoplecostominae have been the subject of various studies, but problems still remain concerning their definitions and compositions in consequence of conflicts resulted from recent molecular and morphological hypotheses. Besides, their largest diversity occurs in the drainages of…

• Abstract

  The project is aimed at the consolidation of the fish collection in the Department of Zoology of Ibilce/UNESP in São José do Rio Preto, by securing resources for the conclusion of its computerization, for the refurbishment of the space it occupies and to buy equipment and consumables necessary for its maintenance. It also proposes to identify batches still not identified up to the level o…

• Abstract

  The diversity of Neoplecostomus Eigenmann & Eigenmann, 1888 increased considerably in recent years. In the only taxonomic review available of the genus, Langeani (1990) recorded only one species to the Rio São Francisco Basin, N. franciscoensis, and also a single species to the Upper Rio Paraná Basin, N. paranensis. Further studies revealed the occurrence of others species in the Upper Ri…

• Abstract

  Neoplecostomus consists of 13 valid species. It was first proposed as a subgenus of Plecostomus by Eigenmann & Eigenmann (1888), including the type species Plecostomus microps Steindachner, 1876, from Rio de Janeiro, rio Paraíba do Sul basin, and Hypostomus granosus Valenciennes, 1840, from Cayenne and Rio de Janeiro. The genus is diagnosed by having two or three conspicuous rows of enlar…

• Abstract

  Since the first hypothesis of phylogenetic relationships for Hypoptopomatinae proposed by Schaefer in 1991, based on morphological characters, the diversity of the subfamily doubled, which had great impact on phylogenies proposed later. There is also a problem involving Hypoptopomatinae and Neoplecostominae about their relationship and component genera, plus there is a large discrepancy b…

(Only some records are available in English at this moment)

• Abstract

  First descriptions of fish of the South America, in particulary in Brazil, were done by European and North American researchers in the 18th century, derived of the big expeditions supported by the Brazilian emperors. So, all type specimens are deposited in the European and North American institutions. The exchange of this material with national institutions has been very hard, because the…
