Abstract

Astyanax biotae Castro & Vari, 2004 was only known from the type locality, a first-order stream from the lower Paranapanema River, a left bank tributary from the upper Paraná river basin. We report A. biotae from the Ivinhema River, rio do Peixe and other tributaries of Paranapanema River, expanding its distribution to both margins of the Paraná River. Astyanax biotae is zooplanktivorous and regarding its conservation status, can be classified as Least Concern.
