Abstract: A new Astyanax is described from the rio Taquari-Antas basin, rio Jacuí drainage, laguna dos Patos system, Rio Grande do Sul State, Brazil. The new species is distinguished from its congeners inhabiting the rio Uruguay, laguna dos Patos and rio Tramandaí basins by the presence of two vertically elongated humeral spots, the anterior humeral spot with the upper portion wider than the lower portion and slightly directed forward, 37-39 perforated scales along the lateral line, 14 scale rows around caudal peduncle,… Show more

“…A total of 79 species of Astyanax was described in the last 20 years (Fricke et al, 2019), being one of the fish genera with higher expansion on its richness knowledge. Advances in alpha taxonomy of the ichthyofauna of the Brazilian coastal drainages contributed with 21 of those descriptions, being 11 from the Northeastern Mata Atlântica freshwater ecoregion (e.g., Rangel-Pereira, 2012;Birindelli et al, 2013;Lima et al, 2013;Mattos, Costa, 2018;Barreto et al, 2018;Burger et al, 2019); seven from rivers draining the Laguna dos Patos freshwater ecoregion (e.g., Lucena et al, 2013;Bertaco, Vigo, 2015), one species from the Tramandaí-Mampituba freshwater ecoregion (Bertaco, 2014), one species from the Ribeira de Iguape freshwater ecoregion (Silva et al, 2019), and one from the Southeastern Mata Atlântica freshwater ecoregion (Oliveira et al, 2013). Particularly to the NMAF, nine of the 11 species mentioned are from river basins inserted in the Bahia State, highlighting the rio Paraguaçu basin, with six described species, all of them apparently endemic to this basin (A. brucutu, A. epiagos, A. hamatilis, A. lorien, A. rupestris, and A. sincora).…”
