Xiru, 20-22 in A. paris, 16-21 in A. obscurus, 15-23 in A. laticeps, 15-20 in A. pirabitira, 20-23 in A. ojiara; 22-24 in A. douradilho; 2-4 maxillary tricuspid teeth (vs. one in A. aramburui, A. dissensus, and A. aff. fasciatus); 37-39 perforated scales along the lateral line (vs. 34-36 in A. paris); and 14 scale rows around caudal peduncle (vs. 15-16 in A. stenohalinus). In addition, A. bagual differs from A. douradilho and A. saguazu by body depth (37.9-45.9% of SL, mean = 43.3%, vs. 34.4-41.0% of SL, mean = 37.0% and 30.9-39.0% of SL, mean = 35.6%); and from A. saguazu and A. stenohalinus by preanal distance (62.4-69.1% of SL, mean = 65.5% vs. 56.0-61.2% of SL, mean = 58.7% and 58.2-62.7% of SL, mean = 59.8%), respectively; and from A. stenohalinus by the anal-fin origin located at vertical through last dorsal-fin ray insertions vs. before a vertical through last dorsal-fin ray insertions. In addition, A. bagual differs from all congeners (including the species complex A. bimaculatusand A. scabripinnis) by the following features: two vertically elongated humeral spots present (the anterior humeral spot with upper portion wider than lower portion and slightly directed forward); 24-28 branched anal-fin rays; 37-39 perforated lateral line scales; outer row of premaxilla with tricuspid teeth, inner premaxilla row with pentacuspid teeth, 2-4 maxillary tricuspid teeth; small bony hooks on all fins of mature males; conspicuous caudal peduncle spot, body depth (37.9-45.9% of SL); preanal distance (62.4-69.1% of SL); anal-fin base length (29.7-35.6% of SL); and orbital diameter (29.5-38.2% of HL) (Ref. 103251).Description: Dorsal-fin rays i,10; anal-fin rays iii or iv, 24, 25, 26, 27, or 28; pectoral-fin rays i,11,12, or 13; pelvic-fin rays i,7; 5 or 6 scale rows between lateral line and pelvic-fin origin (Ref. 103251).
