In addition, this species differs from most congeners, except from A. taeniatus, A. ribeirae, A. hastatus, A. burgerai, A. giton and A. bahiensis, by its humeral spot shaped like a comma. It can be diagnosed from A. taeniatus by having teeth asymmetrical and with no gap on the dentary symphysis (vs. teeth symmetrical and with a gap on dentary symphysis). It can be differentiated from A. ribeirae, A. hastatus, A. burgerai, A. giton and A. bahiensis by having only one humeral spot (vs. two humeral spots) (Ref. 119398).Description: Dorsal-fin rays ii, 9; anal-fin rays iii-iv, 18-22; pectoral-fin rays i, 11-13; pelvic-fin rays i-ii, 7-8; horizontal scale rows between lateral line and pelvic-fin origin 4-6 (Ref. 119398).
