Aspredo
Aspredo aspredo
John P. Friel
Introduction
Members of the genus are the largest aspredinids. They occur from the Orinoco delta, through the Guianas, to the Amazon. Aspredo appears to enter further into freshwater rivers than other Aspredini.
Characteristics
Diagnosis
A genus of large banjo-catfish (up to 385 mm SL) distinguished from all other aspredinids by the following: humeral processes expanded often contacting posterior coracoid processes in large specimens. Other characters not unique to this genus but useful for identification include the following: maxillary barbel adnate with head; one pair of accessory barbels present; body pigmentation uniform without any pattern of dark saddles; and unculiferous tubercle rows highly reduced.
