简单描述
型态特徵 | 形态测量图
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).
在组合特徵之后与它所有的同类区分了藉由: 淡黄色的吻部有被对比边缘不连续的线划界的锐利; 在胸棘的后缘上有 4-6个小的锯齿; 头部宽度 20.3-25.5% SL; 尾柄 5.5-7.1% SL 的深度; 臀鳍基底 9.7-16.6% SL 的长度; 鼻触须 16-38% HL 的长度; 5个鳃条骨; 而且尾鳍边缘深凹.(参考文献 30226)
