Relevant Information:

The genus Pseudolithoxus includes four species, P. anthrax, P. dumus, P. nicoi, and P. tigris, previously described as the Lasiancistrus anthrax group. They are characterized by evertible cheek plates, a very dorsoventrally flattened body, extremely hypertrophied odontodes (integumentary teeth) on elongated pectoral spines and along the snout margin, and 3 rows of plates on the caudal peduncle. In addition, it appears as if females as well as males develop hypertrophied snout and pectoral-fin odontodes, traits normally restricted to nuptial males in other Loricariids. Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 5. Body and head with numerous black bars. Lateral line plates 23-24; dorsal plates 7-8; interdorsal plates 4-5; adipose-caudal plates 7-8; folded dorsal fin plates 11-12; and postanal plates 11-12
