The males of this species are distinguished from all other species of the A. limoncochae species group by having a few golden dots limited on caudal peduncle and on sides between dorsal and anal fin (vs. greenish golden coloration over whole sides when present). It is further distinguished through a combination of the following character states: caudal fin rounded (vs. subtruncate to truncate in A. intermittens, A. iridescens, A. limoncochae, A. rubrolineatus, A. taeniatus), by the number of dorsal-fin rays 8-9 (vs.10 in A. corpulentus), with scales around caudal peduncle 14 (vs. 16 in A. hoetmeri, A. luitalimae, 17-18 in A. christinae, A. corpulentus), with scales on longitudinal series 43-44 (vs. 48-52 in A. elongatus, 38-41 in A. christinae), males with five thin longitudinal stripes on caudal peduncle (vs. three broad stripes in A. erberi, six lines, with three interrupting at the level of anal fin origin in A. hoetmeri, six to seven broad lines in A. corpulentus), longitudinal stripes extending from caudal-fin base up to humeral region (vs. extending anteriorly to pectoral fin in A. lineasoppilatae), with longitudinal stripes narrower than interspace (vs. irregular interrupted lines of dots wider than the interspaces in A. parlettei), by longitudinal stripes on side with same width (vs. with two stripes wider than others in A. urubuiensis), with dorsal fin with white coloration at proximal portion (vs. pale yellow in A. urubuiensis, A. parlettei, A. lineasoppilatae, A. luitalimae, A. iridescens, A. limoncochae; pale brown in A. rubrolineatus, A. taeniatus, A. elongatus; yellowish to orange in A. christinae and white with golden patch in A. hoetmeri) (Ref. 130460).
