Introduction
Although this genus is not well represented in most museum collections, it appears to be widespread in the Magdalena, Orinoco, Amazon and Paraguay-Parana systems. This is certainly due to the fact that these fishes are most common in deeper waters and most specimens have been collected in bottom trawls.
Characteristics
Diagnosis
A genus of moderately sized banjo catfishes (up to mm 147 mm SL) distinguished from all other aspredinids by the following characters: eyes highly reduced; premaxillae toothless and displaced lateral to mesethmoid; row of fleshy papillae projecting anteriorly off lower lip as shown below; unculi and unculiferous tubercles flattened; lamina of pterotic are rounded; and lateral end of posterohyal expanded, Other characters not unique to this taxon but useful for identification include: openings of anterior nares with papillae; coronomeckelian absent, Meckel's cartilage with high ascending process; premaxillae edentulous; pre-axial serrations absent.
