- Aspredinichthtys tibicen Valenciennes, 1840
The two species placed in this genus are very similar in appearance and are most readily separated by the pattern and number of accessory mental barbels. See Mees (1977) for a key to species. This genus occurs from the Orinoco delta, through the Guianas, to the Amazon delta.
A genus of large banjo-catfishes (up to 220 mm SL) distinguished from all other aspredinids by the following characters; dorsal hook-like processes developed on mesethmoid; hooks developed on antorbital bones; 8 pectoral-fin rays; and several pairs of accessory mental barbels present.
