A New Name for Alpine Populations of Hesperia colorado (Scudder) (Hesperiidae, Hesperiinae) in Colorado

ABSTRACT. A reevaluation of the lectotype and type locality of Pamphila (=Hesperia) colorado Scudder indicates that populations in Colorado which were described as Hesperia comma oroplata Scott (=H. colorado oroplata) are synonymous. Based on an examination of numerous specimens, a new subspecies is described for alpine (mainly above timberline) populations in Colorado, which were previously attributed to the nominotypical subspecies. Patterns of geographic variation observed among subspecies of H. Colorado in Colorado and bordering states are also reviewed.
