The municipality of São José do Barreiro, located in the Paraíba Valley, São Paulo, presents topographic complexity, wide altitude variation, and remarkable climatic diversity, contributing to a high diversity of species. Studies that provide basic data about herpetofauna are important for understanding the structure and composition of communities. The present study aimed to elaborate a snake inventory in the municipality of São José do Barreiro for characterizing the richness and abundance of the species Data collection was carried out by consultations with scientific collections and field collections through active search, occasional meetings, and pitfall traps. A total of 255 snakes belonging to 33 species distributed in four families were recorded: Colubridae (N = 5), Dipsadidae (N = 130), Elapidae (N = 5), and Viperidae (N = 112). The most abundant species was Crotalus durissus terrificus (n = 58), followed by Bothrops jararaca (N = 25), and Atractus zebrinus (N = 24). Viperidae was the family with the highest number of records and the second richest family. The abundance of viperids may be justified by the fact that Butantan Institute suppliers collect more venomous animals because of their risk. Most of the individuals registered for the Municipality of São José do Barreiro come from scientific collections, totalling 207 specimens, and the remaining 48 were collected in the field. When compared to other Atlantic Forest regions where herpetofauna inventories were carried out, São José do Barreiro has a high species richness, emphasizing the importance of the natural remnants conservation in the region.
