New records of Atractus ronnie (Serpentes, Colubridae) in relictual forests from the state of Ceará, Brazil, and comments on meristic and morphometric data

Atractus ronnie was recently described from Serra de Baturité, a mountainous relictual forest enclave in the semiarid Caatinga, state of Ceará, northeastern Brazil. Here we report new records of A. ronnie in two other areas of relictual forests and provide additional data on pholidosic variation. The results presented herein reinforce the need for systematic inventory surveys in the relictual forests of Ceará, since the herpetofauna remains poorly known.
