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.
Highlights
The discovery of A. biotae in 2004 was a result of the extensive fauna study implemented by the Program BIOTA/FAPESP through the thematic project “Fish diversity of the headwaters and streams of the upper Paraná river system in the state of São Paulo, Brazil”
Castro and Vari (2004) described A. biotae solely based on material from the lower Paranapanema River, its type locality
The type locality of A. biotae is a first order creek surrounded by a narrow area of native vegetation
