Friel, J.P. (2008): Pseudobunocephalus, a new genus of banjo catfish with the description of a new species from the Orinoco River system of Colombia and Venezuela (Siluriformes: Aspredinidae). Neotropical Ichthyology 6 (3): 293-300

abstract (from publication):
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 contains 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.
