PterobunocephalusJohn P. Friel
- Pterobunocephalus depressus (Haseman, 1910)
- Pterobunocephalus dolichurus (Delsman 1941)
This genus is rare in museum collections but is widespread in the Orinoco, Amazon and Paraguay-Parana River systems. Based on my trawl collecting experiences they typically occur in waters >5 m in depth.
A genus of small to medium sized banjo-catfishes (up to 90 mm SL) distinguished from all other aspredinids by the following characters: head and body extremely depressed; head ornamentation highly reduced or absent; often a distinct notch in upper jaw; laminar process of pterotic needle-like and directed at a shape right angle; 10-20 anal fin rays; and females carry embryos directly attached to the ventral surface of their bodies as shown below.
