Diagnosis

This species is distinguished from A. nudiceps by the presence of two dark vertical bands

of pigment on the body; a larger body depth at the origin of the anal fins; and a shorter snout and jaw length.The smallest adult specimen examined was 12.73 mm SL, although the sex was not determined. It is unknown when the characteristic dark vertical bands develop in this species, although it has been reported that these do not appear on larvae up to 2.07 cm SL (Ref. 131869).
