Distribution Nearctic: Canada (AB, BC, YT, ON), U.S.A. (AK, CO, NH, NY, WY), Mexico ( MEX ). Remarks Rudolfina digitata , the second species to be described in this originally Palaearctic genus, is widely distributed in western North America and also occurs in a few eastern North American sites, including Mount Washington , New Hampshire . Mount Washington is known to have other species with disjunct western Cordilleran and eastern Appalachian distributions (e.g., Oeneis melissa (Fabricius, 1775) ( Lepidoptera : Nymphalidae )), and the apparently disjunct population of R. digitata there suggests it may have once had a more extensive range. The other New Hampshire locality is also one of two known localities for the rare monotypic sphaerocerid genus Volumosina Roháček & Marshall, 2017, otherwise known from one old growth forest in Ontario . The male abdomen is most similar that of the Palaearctic R. zhangi .
