The driftwood catfishes are a family Auchenipteridae of scaleless catfish found in rivers from Panama to Argentina.

All but one species have three pairs of barbels, with the nasal barbels absent. The adipose is rarely absent, but is very small. While Ageneiosus inermis is known to reach 59 cm in length, most are small, with some species not known at any longer than 3 cm. Internal insemination is probable for all species.

The two genera of the family Ageneiosidae have been recently placed here, resulting in a grouping of about 60 species in about 19 genera.
