Occurrence of Pseudocorynopoma heterandria Eigenmann, 1914 (Characidae) in Paraíba do Sul River Basin (Southeastern Brazil)

Abstract

Pseudocorynopoma heterandria Eigenmann, 1914 is a characid related to streams and lakes of clear waters in areas of low and medium altitude (Menezes et al., 2007). The original distribution of this species is in the coastal rivers of S~ao Paulo and Paran a, Brazil (Reis et al., 2003), and has never been recorded below 23°S latitude. In this study we report the first record of P. heterandria in the Para iba do Sul River (20°260–23°380S; 41°000–46°300W), which is located outside of its original area of occurrence. We compared morphometric characteristics of P. heterandria from the Para iba do Sul River basin with the original description of Eigenmann (1914), since local environmental constraints may influence morphological divergence in this species. Additionally, we report for the first time the length–weight relationship (LWR) for this species.
