Pseudobunocephalus, a new genus of small banjo catfishes (< 80 mm SL), is distinguished from all other aspredinid genera by the following unique features: mandibular teeth restricted to a patch near symphysis of lower jaw; no contact between the metapterygoid and quadrate; autopalatine posteriorly forked with two separate cartilages; absence of the fourth pharyngobranchial; absence of gill rakers on all branchial arches; and lack of bifid hemal spines on vertebrae that articulate with anal-fin pterygiophores. As defined Pseudobunocephalus contain a new species, P. lundbergi from the Orinoco River basin, along with five other species previously assigned to the genus Bunocephalus: P. amazonicus, P. bifidus, P. iheringii, P. quadriradiatus, and P. rugosus.
