The Chihuahuan Desert from central Texas through the panhandle, and into southern New Mexico and north central Mexico.
These lizards are found in semi-arid rocky areas with lots of crevices for hiding.
This lizard is distinguished by the spiny scales on its legs and tail, unique banded pattern, and thick black collar outlined in white across its shoulders. Its sides and legs are light grey while its back has darker grey centralized bands with faded edges that get darker towards the tail and turn into solid black bands part way down the tail. It has a row of spiked scales that line the back of its head, and down each side of the neck. Males often have blue patches on the ventral sides of their belly. Can reach 12 inches in total length.
