简单描述
检索表 | 型态特徵 | 形态测量图
Differs from A. grandoculis and A. microlepis for lack of a small, dark spot behind the opercle. Scales on lateral line 74-85; scale rows between the lateral line and the dorsal fin 12-14. Distinguishable from the remaining Venezuelan congeners, except A. nasutus, by its small size up to 9.15 cm SL and by the presence of a narrow, dark line that extends from behind the opercle to about two thirds of the body length (Ref. 52916).
因为没有在鳃盖后面的一个小又深色的斑点，有别于 A. grandoculis 与 A. microlepis 。 在侧线 74-85 上的鳞片; 在侧线与背鳍 12-14 之间的鳞片列. 除了 A. nasutus 以外,可与剩余的委内瑞拉同类区别, 用它的体型小向上到 9.15 公分 SL 而且藉由有狭窄，从鳃盖到大约三分之二的体长的在后延伸的黑色线条.(参考文献 52916)
