Squamate reptiles from seasonal semi-deciduous forest remnants in southwestern Bahia, Brazil

摘要

We present a list of Squamata from Serra do Mandim and Serra Azul, both in the Atlantic Forest domain of Southern Bahia, Brazil. We recorded 27 species (21 snakes and six lizards). Most species can be characterized as generalists with a wide distribution as Phyllopezus pollicaris, Salvator merianae, Corallus hortulanus, Philodryas olfersii, Oxyrhopus trigeminus and Pseudoboa nigra. However, some of the species are considered as being difficult to sample and restricted to forest fragments such as Bothrops bilineatus, Dipsas sazimai and Echinanthera cephalostriata. The snake fauna of both areas represents 70% of the species previously known for the semi-deciduous forests of the state of Bahia. Although the study region is under severe anthropogenic pressure, especially due to the expansion of livestock areas, some forest remnants still withstand a rich reptile diversity.
