Pseudacanthicus histrix is a large species of armored catfish endemic to Brazil where it occurs in the Rio Negro and lower Amazon basins. This species grows to a total length of 90 cm (3 ft). P. histrix has incredibly elongated odontodes that form a brush on the anterior margin of the pectoral fin spine in breeding males; however, sexual dimorphism has not been reported for the other Pseudacanthicus species.
