背棘 (总数) : 1; 背的软条 (总数) : 6; 脊椎骨: 34. Possible a very small species. Snout moderately projecting; cheeks relatively expanded; head terete. Anterior naris very near snout tip (distance between naris and snout tip less than eye diameter). Nasal barbel extending to eye; maxillary barbel reaching only to end of pectoral fin; maxillary-barbel membrane broadly attached to head only on cheek; maxillary bone reaching posteriorly to midway between eye and end of head. Vent opening directly to exterior; vent and genital papilla located between anterior third of pelvic fins. Dorsal and pectoral fins without filamentous extensions Anal fin with 4-5 simple rays, 7-8 branched rays, total 11-13 (Ref. 40780).
