First records of Tropidurus callathelys and T. chromatops (Reptilia: Squamata: Tropiduridae) in Brazil

Abstract

We present the first records of Tropidurus callathelys and T. chromatops in Brazil, at Parque Estadual Serra Ricardo Franco, Mato Grosso. The two species are largely syntopic and associated with rock outcrops on the plateaus of the Serranía de Huanchaca, Bolivia and Brazil. Tropidurus callathelys is more abundant, more heliophilous and uses vertical surfaces more often than T. chromatops. In Brazil, they are apparently restricted to Serra de Ricardo Franco, a protected area threatened by cattle raising, logging and agriculture, still in need of demarcation and a management plan.
