简单描述 检索表 | 型态特徵 | 形态测量图

Differs from all putative congeners by having 17-19 gill rakers on the lower limb of the first arch (vs. 11-17). Further distinguished from all congeners by the combination of the following characters: a slender body, with depth 3.7-4.2 times in SL; 14-15 branched anal-fin rays; 26-28 lateral line scales, all of which bear lateral canals; flanks with golden-bronze reflective coloration overlain by dark brown chromatophores, and dark midlateral pigmentation stripe absent (Ref. 55980).
有别于所有的想象同类在第一个弓的下面肢翼上借着具有 17-19个鳃耙.(vs.11-17) 进一步与所有的同类区分了藉由下列特征的组合: 一个细长的身体, 随着深度 3.7-4.2 标准体长比率; 14-15个分枝的臀鳍棘条; 26-28个侧线鳞片 , 全部都有侧线管; 侧面有金色的-深褐色色素胞的青铜色反射颜色 overlain, 与深色的侧面中央的颜色斑纹不存在.(参考文献 55980)
