A new species of Microglanis (Siluriformes: Pseudopimelodidae) from the rio Uruguay drainage, Brazil Neotropical Ichthyology
Bertaco,Vinicius A.; Cardoso,Alexandre R..
A new pseudopimelodid catfish, Microglanis malabarbai, is described from the rio Ijuí drainage, tributary of the middle rio Uruguay, Rio Grande do Sul, Brazil. The new species is distinguished from all other Microglanis species by the caudal fin color pattern, almost completely black, with a narrow vertical white band across central portions of the caudal-fin rays. Furthermore, it is distinguished from M. cottoides and M. eurystoma, both from rio Uruguay drainage, by head length, maxillary barbel length, internareal distance, and number of lateral-line pores, and from M. cibelae from the coastal drainages of northern Rio Grande do Sul and southern Santa Catarina states, by head length, maxillary barbel length, and body width. A key is presented for the...

Bunocephalus erondinae, a new species of banjo catfish from southern Brazil (Siluriformes: Aspredinidae) Neotropical Ichthyology
Cardoso,Alexandre R..
Bunocephalus erondinae, a new species of banjo catfish is described from the laguna dos Patos system, Rio Grande do Sul, Brazil. The new species differs from its congeners by the bony epiphyseal bar very wide (vs. narrow). Bunocephalus erondinae is externally most similar to Bunocephalus doriae (rio Uruguay and rio Paraná-Paraguay basins), however, differs from this species by the following characters: the bony epiphyseal bar very wide (vs. narrow); metapterygoid round, width is equal the height (vs. metapterygoid elongate, width lesser than half of height), well developed lamina in the hypohyal and anterior ceratohyal bones (vs. little developed or absent), 32 vertebrae (vs. 34-35), first procurrent caudal-fin rays well developed (vs. vestigial),...

Two new Amazonian species of armored catfishes (Siluriformes: Loricariidae): Ancistrus verecundus and Ancistrus parecis Neotropical Ichthyology
Fisch-Muller,Sonia; Cardoso,Alexandre R.; Silva,José F. P. da; Bertaco,Vinicius A..
Two new species Ancistrus are described: A. verecundus from the upper rio Madeira basin and A. parecis from the upper rio Juruena, rio Tapajós basin, Brazil. The two species differ from all congeners except A. jataiensis, A. reisi, and A. tombador in the absence of an adipose fin which is replaced by a series of median platelets forming a low postdorsal ridge. Ancistrus verecundus is further distinguished from these species, except A. tombador by the broad naked margin of the snout and reduced tentacle development. Ancistrus verecundus differs from A. tombador in various morphometric features, and in having the base of the first anal-fin pterygiophore covered by skin (vs. base of the first anal-fin pterygiophore exposed and forming a platelet-like...

Two new species of the banjo catfish Bunocephalus Kner (Siluriformes: Aspredinidae) from the upper and middle rio São Francisco basins, Brazil Neotropical Ichthyology
Carvalho,Tiago P.; Cardoso,Alexandre R.; Friel,John P.; Reis,Roberto E..
Two new species of banjo catfish of the genus Bunocephalus are described from the upper and middle rio São Francisco basins of Brazil. Bunocephalus hartti is distinguished from all its congeners by the absence of serrations along the anterior margin of pectoral-fin spine in adults (vs. presence of serrations along the anterior margin of the spine). Bunocephalus minerim can be diagnosed from all congeners,except B. larai, by the absence of an epiphyseal bar between the paired frontals (vs. presence of the epiphyseal bar at least in adults). Bunocephalus minerim is distinguished from B. larai and other congeners, except B. chamaizelus , by having nine principal caudal-fin rays (vs. 10 principal caudal-fin rays).
