is a common and widespread species in western North America. The population occurs over a wide range, and no decline has been noted. It is listed as Least Concern (LC).
Described based on collections from Washington and Oregon, USA (Bas 1969).
This species occurs in the Pacific Northwest of North America, from southern British Columbia, Canada, south from the coast to the Cascade Range, through the Sierra Nevada, California, and coastally into Santa Cruz County, California, USA. It is also expected to occur in the northern Rocky Mountains. It has been reported from single collections from Idaho, New Mexico and Mexico (Tulloss 2021), but these collections should be scrutinized more.
