Oxyrhopus clathratus Dumeril, Bibron & Dumeril, 1854

Natural history notes.

Species of medium size (n = 1), terrestrial and nocturnal ( Marques et al. 2001). A recently road-killed adult male was found in an open area near the PESP, during the morning. There was no evidence of diet or reproduction of the examined specimen. The available information in the literature indicates a diet composed mainly of mammals, although lizards and birds can also be prey ( Hartmann et al. 2009b, Gaiarsa et al. 2013). Reproduction is seasonal, with a reproductive peak in the summer ( Marques and Sazima 2004). Fecundity varies from four to 16 eggs ( Gaiarsa et al. 2013). No defensive behavior was observed for this species.

Altitudinal variation.

The species is found at a minimum of sea level from the coast of Rio Grande do Sul to Rio de Janeiro, and a maximum of 1610 m a.s.l. in Campos do Jordão, SP ( Bérnils 2009). In this study, we found this species outside the PESP limits, at 1000 m a.s.l. in the Aiuruoca, MG. Total altitudinal range is broad with 31.7% of toponyms found from the sea level up to 400 m a.s.l., 36.6% between 401 and 800 m a.s.l. and 31.7% above 801 m a.s.l. ( Bérnils 2009).

Distribution and habitat.

Northeast and southeast Brazil (Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo), and Argentina ( Wallach et al. 2014, Bernardo et al. 2012). It occurs in dense, mixed ombrophilous and seasonal semidecidual forests ( Bernardo et al. 2012).
