Lampropeltis leonis (Nuevo Leon Kingsnake)
Doctor Arroyo to Aramberri, Southern Nuevo Leon
The region from Doctor Arroyo (elev. 5669 ft/1727 m) northward to La Escondida (elev. 4914 ft/1497 m) and Aramberri (elev. 3589 ft/1094 m) provides a variety of habitats from desert to woodland, from large expanses of barren, rocky ground to areas with abundant vegetative cover. Much of it is grown to Chihuahuan Desert scrub vegetation—mesquite, cacti, agaves. A small number of Nuevo Leon Kingsnakes have been found here, and some of these have formed the founder stock for today’s captive lines. Other snakes observed in this region include Mexican Pine Snakes (Pituophis deppei), Mexican Lyresnakes (Trimorphodon tau), Texas Nightsnakes (Hypsiglena torquata jani), Great Plains Ratsnakes (Pantherophis emoryi), Western Diamondback Rattlesnakes (Crotalus atrox), and Mexican Black-tailed Rattlesnakes (Crotalus molossus nigrescens) (July 1996, July 2005).
