About the Distribution Map 

Knowledge concerning the Mexican distribution of the various Mexicana kingsnakes is meager and for many areas non-existent. The majority of the relatively few known localities within Mexico have received repeated visits from herpetologists and hobbyists over the past several decades, while there has been comparatively little effort given to exploration of new areas. Thus, the range map presented here contains abundant speculation, combining known records with our knowledge of habitats, greatly aided by input from friends and colleagues having relevant field experience. As drawn, the map omits point localities, instead offering up only broad generalizations concerning hypothetical ranges. Ongoing field studies by Mexican and American herpetologists will undoubtedly contribute new records, and we will periodically update the map to reflect new information.

The map below depicts the physical geography of Mexico. We include it here to give readers some idea of the remarkable topographic diversity that characterizes the collective range of Mexicana Kingsnakes.
