| Remarks | Males possess the following: brush-like pads of tubercles on the heads, a weakly delimited pad of minute, granular tubercles on each side of preorbital region; broadened and thickened external (the first 6 or 7) branched pectoral-fin rays, dorsally covered by small, round and condensed epidermal tubercles. Females have tip of pectoral fin acuminate and length is subequal to or slightly longer than that of males. Females lack tubercles on head and pectoral-fin rays (Ref. 92369). |

| Diagnosis |
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). |
