簡短描述 檢索表 | 型態特徵 | 形態測量圖

背的軟條 (總數) : 6; 臀鰭軟條: 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).
在組合特徵之後與它所有的同類區分了藉由: 淡黃色的吻部有被對比邊緣不連續的線劃界的銳利; 在胸棘的後緣上有 4-6個小的鋸齒; 頭部寬度 20.3-25.5% SL; 尾柄 5.5-7.1% SL 的深度; 臀鰭基底 9.7-16.6% SL 的長度; 鼻觸鬚 16-38% HL 的長度; 5個鰓條骨; 而且尾鰭邊緣深凹.(參考文獻 30226)
