Morphology | Morphometrics
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). It differs from saguazu, elachylepis, and fasciatus species complex by the autapomorphic presence of a space between the dentary teeth, which are relatively slender, with cusps positioned close to one another, and by the presence of a maximum of five cusps in each dentary tooth (vs. maximum of 7 cusps). 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).
