Snout rounded, 3 times in length of head; diameter of eye 5 times in length of head, interorbital width 3 times; mouth inferior, its width 4 times in length of head ; lips well-developed, lower continuous; barbels two on each side, subequal, nearly twice as long as eye, the distance between them half their length. Dorsal IY 8, last simple ray strong, bony, not serrated, slightly curved, J length of head ; free edge of the fin emarginate ; its distance from the occiput less than its distance from the caudal.
