背的软条 (总数): 5-6; 臀鳍软条: 8 - 9; 脊椎骨: 31 - 33. Distinguished from all its congeners by the following combination of characters: truncate caudal fin; presence of 4 serrae along posterior edge of pectoral spine; slightly concave lateral margins of the head when viewed dorsally; eyes located laterally with a suborbital depression; body depth at anus 8.9-13.5% SL; depth of caudal peduncle 6.1-8.6% SL; length of dorsal-fin base 13.1-22.1% SL; length of adipose-fin base 18.4-25.2% SL; and eye diameter 14-20% HL (Ref. 30226).
在组合特徵之后与它所有的同类区分了藉由: 截形尾鳍; 有 4个锯齿沿着胸棘的后缘; 当背面看了,些微地凹曲头部的侧面边缘; 侧面地被设置的眼具有一个眶下的凹洼; 在肛门 8.9-13.5% SL 的体高; 尾柄 6.1-8.6% SL 的深度; 背鳍长基底 13.1-22.1% SL; 脂鳍基底 18.4-25.2% SL 的长度; 而且眼直径 14-20% HL.(参考文献 30226)
