Global Range: (1000-5000 square km (about 400-2000 square miles)) Historical range includes the San Bernardino and San Jacinto mountain ranges in southern California (Grinnell 1908, 1933; Grinnell and Swarth 1913; Hall 1981; Wells-Gosling and Heaney 1984). A report of this species as occurring in the San Gabriel Mountains (Vaughan 1954) lacks documentation. The range is disjunct from other populations of this species (separated from Sierra Nevada populations by unsuitable habitat in the vicinity of Cajon Pass), and it represents the southernmost extend of the species' global range (Wells-Gosling and Heaney 1984). The population in the San Jacinto Mountains is disjunct from the populations in the San Bernardino Mountains by unsuitable lowland habitat around Banning Pass (Hall 1981) and San Gorgonio Pass, through which Interstate Highway 10 passes. Elevational range is about 1,220-2,590 meters (4,000-8,500 feet).

Extent of occurrence probably is not more than 5,000 square kilometers.
