背的软条 (总数) : 11; 臀鳍软条: 21; 脊椎骨: 47. Distinguished from all its congeners by the combination of the following characters: fifth infraorbital bone higher than wide, the presence of several narrow, wavy longitudinal stripes along the dorsolateral surfaces of the body, the darkened pectoral and pelvic fins, the presence of a distinct crescent- or V-shaped blotch on caudal peduncle and caudal fin, and the possession of 66-82 lateral line scales (Ref. 55407).
与它所有的同类区分了藉由下列特征的组合: 第五个眶下骨比较高的超过宽的, 那有一些狭窄又纵向波浪斑纹沿着身体的背外侧表面, 颜色较深胸鳍与腹鳍, 那有明显的新月- 或者 V 形的斑块在尾梗上与尾鳍, 而且拥有 66-82个侧线鳞片.(参考文献 55407)
描述: 背鳍鳍条 ii,9; 臀鳍棘条 iii, 18-24; 胸鳍鳍条 i,12-15; 腹鳍鳍条 i,6-8.(参考文献 55407)
