Differs from congeners by having ventralmost pectoral fin rays exserted, scales present on posterior 2/5 of body, dorsal fin rays 76-80, and anal fin rays 64-66. It is further diagnosed by the following combination of characters: suborbital head pores 6-7, preoperculomandibular pores 8; predorsal length 28.0-30.7% SL; snout length 28.3-36.6% HL, eye diameter 9.4-12.0% HL; pectoral fin rays 14-16; anterior dorsal fin pterygiophore associated with vertebra 6-7; vertebrae 23-27 + 61-63 = 86-89.</paragraph>

Vertebral centra symmetrical, with prezygapophyses and postzygapophyses of equal horizontal length. Anal fin pterygiophores 3 (3-4), inserted anterior to haemal spine of first caudal vertebra. Caudal fin with 1 epural, 4 upper and 5 lower hypural rays. Epipleural ribs on 3 (3-4) to penultimate precaudal vertebra. Gill rakers on outer surface of first gill arch simple (not furcate) and with spinules. Branchiostegal rays 6. Pectoral fin wedge-shaped; its origin below body midline; lower rays thickened, exserted. Pelvic fin absent.</paragraph>

Eyes relatively large, circular, not reaching dorsal profile of head. Mouth subterminal; lower lips without lateral lobe, upper lip continuous across snout. Snout blunt, upper jaw slightly longer than lower jaw, reaching past middle of eye. Nasal tube well developed, but not reaching upper lip.
