It differs from other congeners, including species complex A. bimaculatus and A. scabripinnis by the following combination of characters: two humeral spots, the first spot vertically elongate; conspicuous caudal spot; 35-39 perforated lateral line scales; 6-7 scale rows between dorsal-fin origin and lateral line; 22-28 branched anal-fin rays; predorsal region scaled; one heptacuspid maxillary tooth; body depth 37.2-44.2% of SL; and head length 22.7-27.3% of SL). It is distinguished from A. ojiara by the head length 22.7- 27.3% (vs. 27.3-29.5% of SL) and by the presence of hooks on anal fin on males (vs. all fins with hooks) (Ref. 94153).
