Abstract

Herein, we report new records for Chiasmocleis carvalhoi from southern regions of Sao Paulo state. We also provided an updated geographic range map and modelled the potential distribution of this species. New records extended the known species distribution about 150 km southwards of the Sao Paulo state coast. Moreover, the geographic range map of C. carvalhoi and its potential distribution evidenced that the distribution of this species is typical to lowlands forests habitats and reinforce its current endangered conservation status.

Highlights

  • We provided an update geographic range map and modelled the potential distribution of this species based on the new records, literature, and museum-based data from “Coleção de Anfíbios Célio F

  • On 16 December 2011, around 22:00 h during a fieldwork in a private ownership, at municipality of Itanhaém, southern coast of São Paulo state (24°11′1.9′′ S, 46°51′44.2′′ W; 20 m a.s.l.), we found three males

  • The potential distribution of C. carvalhoi modeled by Maxent (Phillips et al 2006) based on occurrence records analyzed and the 19 bioclimatic variables (Hijimans et al 2005) shows that this species is constrained to lowlands

Summary

Introduction

Records from Espírito Santo state were provided (Almeida et al 2011), filling a gap between seemly disjoint populations of this species (Pimenta and Peixoto 2004). The known southward limit of its distribution is the Ubatuba municipality on the northern coast of São Paulo State (Hartmann et al 2002). We report new records for Chiasmocleis carvalhoi from southern regions of São Paulo state.
