Range Description

This species is known only from California in the United States. It 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, Cosos Mountains (Banta et al. 1996). Its occurrence in talus habitat suggested to Banta et al. (1996) that the geographic range may be broader than is now known. However, the known area of occupancy is very small (probably less than 5 sq. km if one assumes that each occupied patch is 2 km long and 0.1 km wide). Elevational range is about 2,500 to 7,500 feet (760 to 2,300 m).
