Dorsale zachte stralen (totaal) : 10 - 11; Anale zachte stralen: 7. Can be diagnosed by the following characters: smooth and scalesless body; tapering and relatively narrow head, head width 47.6-54.0% HL; eye diameter 12.1-17.6% HL; thin and smooth lips; slender and laterally compressed trunk; caudal-peduncle length 20.0-23.8% SL; slender, laterally compressed (cross-section of caudal peduncle elliptic) and tapering caudal peduncle , with trunk towards the base of caudal fin; pelvic fin insertion anterior to dorsal-fin origin; dorsal-fin origin closer to caudal-fin base than to snout tip; caudal fin deeply concave; lateral line complete; posterior chamber of gas bladder reduced or absent; intestine short, in zigzag pattern posterior to bottom of ‘U’-shaped stomach (Ref. 92369).
