Number of Occurrences

Unclear. Dondale et al. (2003) may include two occurrences, however, one overlaps the NWT-Alberta border near Highway 1 and one overlaps the NWT-Yukon border; it is unclear which jurisdiction these two occurrences were recorded from. There are also two more recent records of this species from near Yellowknife (GBIF). References: (1) Dondale, C.D., Redner, J.H., Paquin, P., & Levi, H.W. 2003. The Insects and Arachnids of Canada.
