Description

See Marshall (1991).

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   .
