Over this base color, there is a series of blotches along the back that are typically split along the midline of the body, resulting in 39–64 pairs of blotches.

In northern Mexico, it lives in the Sierra Madre Occidental across the states of Sonora, Chihuahua, and Durango. It is also present in the Sierra Madre Oriental in southeastern Coahuila, Nuevo León, and Tamaulipas, with individual isolated records from the states of San Luis Potosí and Aguascalientes.
