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: 9 - 10; 脊椎骨: 31 - 32. Distinguished from all its congeners by the following unique combination of characters: slender body (body depth at anus 8.2-10.3% SL; depth of caudal peduncle 3.5-4.5% SL); extremely narrow head (head width 17.5-20.2% SL); small and close-set eyes (eye diameter 6-10% HL; interorbital distance 20-26% HL); short nasal barbels (11-17% HL); the presence of 6-8 serrae along the posterior edge of the pectoral spine and 8-9 branchiostegal rays; and caudal fin strongly forked with pointed lobes (Ref. 30226).
在獨特的組合特徵之後與它所有的同類區分了藉由: 細長的身體 (在肛門 8.2-10.3% SL 的體高; 尾柄 3.5-4.5% SL 的深度); 非常狹窄的頭部 (頭部寬度 17.5-20.2% SL); 小的而且靠攏在一起眼 (眼直徑 6-10% HL; 眼間距 20-26% HL); 短的鼻觸鬚 (11-17% HL); 那有 6-8個鋸齒沿著胸棘與 8-9個鰓條骨的後緣; 而且強烈地分岔的尾鰭有尖的葉.(參考文獻 30226)
