Remarks
There are only two species with a widespread eastern distribution (C. albitarsis and C. persimilis). Within the east, C. albitarsis is readily separated from other species by the entirely black legs (apart from white hind tarsi in the males). Other species have at least the hind femora fulvous or fulvoferruginous. Care should be taken where multiple species overlap in the west as these species will not always be readily distinguishable in photographs.
