Etymology: Astyanax: The name of Astyanax, Hector´s son in the Greek mythology (Ref. 45335); bagual: The specific name bagual, from Tupi- Guarani, refers to wild horse, or what is mortal, or dangerous to mount. This expression is used mainly to convey the information that a given horse is a male reproductive in the countryside of Rio Grande do Sul State. This is allusion to the presence of bony hooks on all fins in mature males.
Eponymy: Astyanax was the son of Hector in Greek mythology. See Homer’s Iliad for details. The reasoning for its use for a genus of characins is not explained. (Ref. 128868), visit book page.

duri punggung lunak (Keseluruhan (total)) : 11; vertebrata, bertulang belakang: 36 - 37. Astyanax bagual is distinsguisded from all congeners occurring in rio Uruguay basin, laguna dos Patos and rio Tramandaí systems by having the following characters: first humeral spot vertically elongate with upper portion wider than lower portion and slightly directed forward
(vs. presence of oval spot with two brown vertical bars in humeral region in A. jacuhiensis, oval spot in A. laticeps, and forming a uniform wedge in A. eigenmanniorum, A. henseli, A. saguazu and A. stenohalinus; two humeral spots (vs. one in A. eigenmanniorum, A. aff. fasciatus (Cuvier), A. jacuhiensis, and A. laticeps); 24-28 branched anal-fin rays (vs. 18 or less in A. brachypterygium and A. cremnobates, 18-23 in A. procerus, and A. 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).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Occurs in relatively small, dark water rivers up to two meters deep, with stones and rocks on bottom, and moderate riparian vegetation. Sampling localities are around 300 meters above sea level (Ref. 103251).
