Abstract

The occurrence of Hypsiglena torquata (Günther, 1860), Night Snake, on María Madre Island, which is part of the Islas Marías Archipelago Biosphere Reserve on the Pacific coast of Mexico, is confirmed through the examination of squamation. This record increases the herpetofaunal diversity of María Madre Island, the largest of the island in the Gulf of California, to 24 species: four amphibians and 20 reptiles. In addition, we provide an updated list of the herpetofauna of María Madre Island.
