Abstract

Garutti (1995) made a revision of some Astyanax (Osteichthyes, Characidae) species and the species called tambiú from the upper Paraná River basin, formerly identified as Astyanax bimaculatus, was considered new. Garutti & Britski (2000) later described it as Astyanax altiparanae (Pisces, Characiformes). However, they did not analyze specimens from the Iguaçu River basin at that time. The Iguaçu River, affluent to the Paraná River, has a high degree of endemism in its ichthyofauna because of the geographic isolation caused by the falls near its mouth. Thus, there were still many doubts regarding the specific status of the population from the Iguaçu River basin, also called A. bimaculatus before Garutti’s studies. To verify if the population from the Iguaçu River belongs to the A. altiparanae species, we compared specimens from both basins and concluded that they belong to the same species, widening their geographic distribution.
