Scientific name Lampropeltis leonis (G√ľnther 1893)
English name Nuevo Leon Kingsnake
Habitat The western part of the distribution area of L. leonis consists of the area where the Chihuahua Desert borders the Sierra Madre Oriental.

Specimens of L. leonis are found in the Chihuahua Desert scrub, which is characteristic of that area, but also in somewhat humid habitats (Aramberri, San Juanito, Galeana). Occasionally these snakes are also found along the road between Doctor Arroyo and Galeana.

The eastern slope of the Sierra Madre Oriental is tropically humid and lushly overgrown thanks to the many rainfalls. The San Roberto Highway (Mex 31), which runs from east to west, from Linares to San Roberto, illustrates this vividly.

On the east side of this road, specimen of the tri-colour morph of L. leonis are found. The snakes are located on the road at night. They live here sympatrically with the Texan coral snake (Micrurus tener).

Distribution This species occurs in some northern parts of the Sierra Madre Oriental, especially in the states of Tamaulipas and Nuevo Leon.

In the far east of Coahuila, there are also specimen found. Animals are known from both the eastern and the western flanks of the Sierra Madre.
