Found in the northern half of the Yucatán Peninsula in Mexico. The type locality given is "Chichen Itza, Yucatán" [Mexico]. This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001). Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is unknown. Year assessed: 2007.
