     Described as Capnia poda. Found in the northern and southern Rockies.
Quote from first page: "The genus Capnia is primarily found in western North America where emergence occurs during the winter and early spring. Several species have restricted ranges and habitat requirements, making them almost unknown to all but those specifically seeking them. Many emerge at high altitudes in the Rocky Mountains in streams which are still isolated by deep snows, making collecting difficult.
The Capnia columbiana complex is found in western and arctic North America where it is represented by C. columbiana Claassen, C. logana n. sp., C. labradora Ricker, C. imbera n. sp., C. lemoniana n. sp., C. trava n. sp., C. sierra n. sp., C. poda n. sp., C. tahoensis n. sp., and C. distincta Frison. This group is readily distinguishable from other capniids by the presence in the male of a bipartite supra-anal process, the upper part of which is more or less bifurcate and enlarged at the tip, and by the presence, in the female, of distinctive patterns of the subgenital area.
