Campbell and Lamar (2004) describe its range as the desert regions of south-central Arizona and parts of western Sonora, exclusive of the panhandle region in the west, but including Tiburon Island in the Gulf of Mexico.

Taxonomy

This subspecies was established by J.M. Savage and F.S. Cliff, based on information that had previously been published by Stanford, Klauber and Hensley. They described their new form, C. c. cercobombus, as occupying the eastern half of the range for C. c. laterorepens as defined by Klauber.
