简单描述
型态特徵 | 形态测量图
Diagnosis: Pored lateral-line scales 81-85; scales above lateral line 8.5-9.5; scales below lateral line 10.5-11.5. Posterior tip of maxilla nor or just reaching to below anterior nostril. Posterior tip of opercle obtuse just above level of pectoral-fin base. A single row of scales in the suborbital groove not covered with skin. Two distinct longitudinal stripes on the side of the body with fresh (upper stripe usually lost in preserved specimens); lower stripe especially distinct, running from tip of snout through upper part of pectoral-fin base, extending to caudal-fin base just below lateral line; membrane of first dorsal fin entirely transparent (Ref. 54823).
鉴别: 有细孔的侧线鳞片 81-85; 鳞片在侧线上面 8.5-9.5; 鳞片在侧线下 10.5-11.5. 颚骨的后部顶端也不或正好延伸到前鼻孔下面。 鳃盖的后部顶端圆头的在胸鳍基底的水平的正上方。 在眶下的凹槽的一个单列的鳞片不覆盖着皮肤了。 二条明显的纵向斑纹在身体有侧边上生鲜地;(上面的斑纹通常失去在保存的标本) 低的斑纹尤其明显的, 经过被在侧线正下方延伸至尾鳍基底的胸鳍基底的上半部从吻尖延续的; 第一背鳍的薄膜完全透明.(参考文献 54823)
