Abstract

Crotalus intermedius Troschel, 1865 is a venomous snake endemic to Mexico, inhabiting high-elevation forests and shrublands. This study presents the first formal record of C. intermedius from the State of Mexico and its potential distribution. Only 11.4% of its potential range overlaps with natural protected areas (NPA), with 10.1% in federal NPAs, including our new record from Monte Tláloc within Iztaccíhuatl-Popocatépetl National Park, and 1.3% in state NPAs. This finding fills a distribution gap in C. intermedius distribution and increases the number of venomous reptile species recorded in the State of Mexico to 16.
