Bunocephalus erondinae, a new species of banjo catfish from southern Brazil (Siluriformes: Aspredinidae)

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), vertebral parapophysis 5 distally expanded, shaped like an axe (vs. not expanded).
