Iliamna crandallii was described from near Steamboat Springs, Routt County, and is restricted to that area. It has been reported from Rio Blanco County (according to a specimen at COLO). T. A. Bodo Slotta (2000) stated that she collected fresh material of the species at Buffalo Pass and Fish Creek Falls.
