Corresponding author: Pedro de Oliveira Calixto, [email protected] Abstract We present an annotated list of herpetofauna for the municipality of João Câmara, Rio Grande do Norte State (RN), Brazil, in Caatinga domain. The data were obtained through fauna rescue program activities performed during the installation of two wind energy parks. We recorded 10 species of lizards, eight snakes, four amphisbaenids and three anurans. The results obtained present extensions to known geographic distribution for four species (Amphisbaena littoralis, Enyalius bibronii, Epictia borapeliotes and Corythomantis greeningi) and add information to the natural his- tory of the first two species. This constitutes the second list of herpetofauna for RN. Our results show that such studies may contribute useful data on herpetofauna, especially in poorly studied areas. Key words Semi-arid; diversity; reptiles; amphibians; conservation.
