Notes.
This species is uncommon and has thus far only been collected in the Cascade Mountains of Washington State in the vicinity of Mount St. Helens at elevations above 850 m. It might be expected to have a broader range on the basis of the range of its host, Cyphoderris monstrosa , which is known to occur in coniferous forest in several Western U.S. states and Canada ( The Orthopterists’ Society 2023).
