Range edit
The sandstone night lizard is extremely limited geographically; it is known only to the Truckhaven Rocks in the Colorado Desert, at Anza-Borrego Desert State Park in eastern San Diego County, California.
Description edit
The lizard is very secretive using small burrows and sandstone or siltstone for cover. The specific name, gracilis, is derived from Latin meaning "slender", referring to the species' slender habitus.[2]
