背的软条 (总数) : 6; 臀鳍软条: 6 - 8; 脊椎骨: 31 - 34. Distinguished from all its congeners by the following combination of characters: light-yellow snout with a sharp, contrasted edge discrete line demarcation; presence of 4-6 small serrae on the posterior edge of pectoral spine; head width 20.3-25.5% SL; depth of caudal peduncle 5.5-7.1% SL; length of anal-fin base 9.7-16.6% SL; length of nasal barbel 16-38% HL; 5 branchiostegal rays; and caudal fin deeply emarginate (Ref. 30226).
Body shape (shape guide): elongated.
