This species is distinguished from A. camelierae by having the anterior midlateral stripe reaching dorsal-fin region (vs. stripe reaching caudal peduncle blotch), second unbranched dorsal-fin ray hyaline (vs. proximal half of second unbranched dorsal-fin ray densely pigmented), caudal peduncle blotch triangular (vs. roundish), lateral line incomplete (vs. complete), longitudinal scales 31-33 (vs. 37-39), ventral margin of third infraorbital bone usually reaching anterodorsal margin of preopercle (vs. surpassing that point), and precaudal vertebrae 12 (vs. 13); differs from A. lu distinguished by the dense concentration of dark brown chromatophores over the first unbranched dorsal and all unbranched anal-fin rays (vs. dorsal and anal unbranched fin rays are poorly pigmented), with two symmetrical conspicuous small dark blotches at the base of the caudal-fin rays (vs. usually absent, very diffuse when present), pectoral-fin rays i9-10 (vs. i8), and with just one unilateral hook at the medial region of each ray segment (vs. one to two (Ref. 130247). |
