A new species of the freshwater fish genus Astyanax (Ostariophysi: Characidae) from the rio Iguaçu basin, southeastern Brazil

Abstract

Astyanax varzeae, a new species of characid fish, is described from the rio da Várzea headwaters, a tributary of the upper portions of the rio Iguaçu in Paraná State, Brazil. The new species belongs to the Astyanax scabripinnis species complex and differs from its congeners by the presence of one or two humeral spots, maxilla with one to three (mostly two) teeth and 15 to 20 (usually 16 to 18) branched anal-fin rays.Astyanax varzeae, uma nova espécie de caracídeo, é descrita das cabeceiras do rio da Várzea, um tributário do trecho superior do rio Iguaçu no estado do Paraná, Brasil.
