Identification Relatively small (less than 80 mm SL) banjo catfishes distinguished from other aspredinids by having the following unique characters: the dentary teeth are restricted to broad tooth patch near symphysis of lower jaw (vs. more broadly distributed along the length of the dentary); the metapterygoid lacks a bony connection with the quadrate; the posterior end of autopalatine is distinctly forked and bears two separate terminal cartilages; the absence of the fourth pharyngobranchial; the absence of gill rakers on all branchial arches; and the lack of bifid hemal spines on vertebrae that articulate with anal-fin pterygiophores. Other characters not unique to this genus, but still useful for distinguishing it from other aspredinid genera include: the anterior limits of upper and lower jaws are approximately equal (also in Acanthobunocephalus); the lateral line is truncated at approximately the level of the dorsal-fin origin (also in Acanthobunocephalus); the dorsal- and ventral-most principal caudal rays much shorter in length than other principal caudal rays (also in Acanthobunocephalus); the dorsal- and anal-fin membranes are not adnate with body (also in Acanthobunocephalus); the interhyal is absent (also in Hoplomyzon); and the abdominal and precaudal centra lack bony horizontal lamina (also in Dupouyichthys, Ernstichthys, Hoplomyzon and Micromyzon).
