Auchenipterus osteomystax

Classification

Auchenipterus is a genus of driftwood catfishes (order Siluriformes). Taxonomy The genus is hypothesized to be monophyletic, diagnosed by the shared presence of grooves in the ventral surface of the head that accommodate adducted mental barbels. The presence of papillae on the dorsal and medial surface of the ossified maxillary barbel of mature males is also a possible synapomorphy, but in three species this cannot be confirmed as there are no adult male specimens yet discovered.
