Etymology: Astyanax: The name of Astyanax, Hector´s son in the Greek mythology (Ref. 45335); guaricana: Named for its type locality, the Guaricana Reservoir of Paraná State, Brazil. A noun in apposition.
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.

背的軟條 (總數) : 9 - 10; 脊椎骨: 39 - 40. This species belongs to the Astyanax scabripinnis species complex sensu. It is distinguished from congeners of the A. scabripinnis species complex, except A. intermedius, A. laticeps, A. paranae and A. varzeae by having 40-43 teral line scales, (vs. less than 39 scales in A. brachypterygium, A. burgerai, A. courensis, A. cremnobates, A. epiagos, A. goyanensis, A. ita, A. jacobinae, A. jenynsii, A. jordanensis, A. leonidas, A. microschemos, A. obscurus, A. ojiara, A. paris, A. pirapuan, A. rivularis, A. scabripinnis, A. totae, and A. troya). Only A. obscurus and A. ojiara have a maximum of 39 lateral line scales. A. guaricana can be separated from A. ojiara, by having 15-17 circumpeduncular scales (vs. 13-14 scales) and A. obscurus, by having 9-15 scales covering base of anal fin (vs. 6-9 scales). It differs from A. intermedius, A. laticeps and A. paranae by the presence of two vertical humeral spots (vs. a single humeral spot in A. paranae and A. intermedius, which is horizontally oval with narrow and vertical anterior extension in A. laticeps); from A. varzeae by the presence of hooks on the anal fin in males (vs. hooks absent), by a shorter prepectoral distance 23.7-26.5% SL (vs. 26.5-32.0% SL), shorter head length 23.9-26.6% SL (vs. 27.1-29.7% SL), and longer snout length 23.3-27.9% head length (vs. 16.4-23.3% head length); and from A. ribeirae by having two humeral spot (vs. one) and 40-43 lateral line scales (vs. 34-38 lateral line scales) (Ref. 93808).
