Global Range: (5000-20,000 square km (about 2000-8000 square miles)) This species is known several locations in desert mountains of Inyo and Mono counties, east-central California (Stebbins 2003). Some specific locations include the following: Panamint Mountains (Brewery and Limekiln springs, Surprise Canyon, Pleasant Canyon, Wildrose Canyon, middle fork of Hanaupah Canyon), Nelson Mountains (Grapevine Canyon), Inyo Mountains (Daisy Canyon, Lime Hill, Long John Canyon, French Spring), White Mountains (Batchelder Spring, Westgard Pass, Marble Canyon, Tollhouse Spring, Black Canyon, Cottonwood Canyon, Silver Creek Canyon, Coldwater Creek, above Chalfant and Hammil valleys), eastern Argus Mountains, and Cosos Mountains (Stebbins 1958, Dixon 1975, Macey and Papenfuss 1991, Jennings and Hayes 1994, Banta et al. 1996, La Berteaux and Garlinger 1998). Occurrence in widespread dry wash and talus habitat suggested to Banta et al. (1996) that the geographic range may be much broader than is now known. Elevational range is about 2,500-7,500 feet (760-2,300 meters).
