Short description

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).
