背的软条 (总数) : 12; 臀鳍软条: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: 13-14 bars on body, the anterior ones not conspicuously wider than posterior ones; maximum head width 16.6-17.4% SL; eye diameter 3.1-3.6% SL, 14-17% HL; interorbital width 7.3-7.8% SL, 35-36% HL (Ref. 39226). Its slender caudal peduncle (1.23-1.53 times longer than deep) and its color pattern distinguish it from any congener (Ref. 39226). Presence of a dark blotch at dorsal-fin origin; a faint blotch at base of posterior rays of dorsal fin; scales very sparse or absent in front of dorsal fin and on belly (Ref. 12693).
Body shape (shape guide): elongated.
一个群种的成员具有完全的或几乎侧线完整,81/2个分枝的背鳍鳍条,9+8个分枝的尾部鳍条与没有性的同种二形。 鉴别的特徵是下列的特徵: 在身体上的 13-14条横带, 前面的一些不明显的比在后部的一些宽; 最大的头部宽度 16.6-17.4% SL; 眼直径 3.1-3.6% SL,14-17% HL; 眼间骨宽度 7.3-7.8% SL ， 35-36% HL.(参考文献 39226) 它的细长尾柄 (1.23-1.53 倍深的) 与它的彩色斑纹区别它和任何的同类。 (参考文献 39226) 在背鳍起点出现一个黑色斑块; 在背鳍的在后部鳍条的基底的一个模糊的斑块; 鳞片非常稀疏的或不存在于背鳍的前面与在腹面上.(参考文献 12693)
