Diagnosis |
This species is distinguished by having the largest scales between the dorsal fin and upper lateral line, only 2 ½ scales (vs. 3 ½); similar to A. facetus, cf. facetus, and minuano in coloration patterns. It is the same with forquilha and tembe, in having a small and inconspicuous midlateral blotch and a straight midlateral stripe (if present), running along the flank in the limits of E0 and E1 scale rows; differs with both in having lower meristics, such as 13 caudal vertebrae (vs. 14 or more), a shorter caudal peduncle, shorter scale cover of the dorsal fin, larger (and fewer) scales and a narrower interorbital space (Ref. 74689). |
