Diagnosis:  Dorsal soft rays (total): 10-11; Anal soft rays: 25-33. Diagnosis: Distinguished from its congeners except A. saguazu and A. elachylepis by the presence of a second vertically elongate humeral spot (vs. one humeral spot).

Differs from fasciatus, rutilus, and elachylepis by the presence of 2 - 5, usually 5, tricuspid teeth on the anterior margin of maxilla (vs. 1 - 2 teeth, usually 1, on anterior margin of maxilla) (Ref. 56653).
