Two new stonefly species in the Sweltsa coloradensis (Banks) Complex (Plecoptera: Chloroperlidae).

摘要

Male reproductive structures were examined with scanning electron microscopy for populations of the Sweltsa coloradensis (Banks) complex from throughout the known range in western North America. Sufficient variation was observed in epiproct structure to recognize and describe two new species. Sweltsa mogollonica, n. sp. is recognized from eastern Arizona and western New Mexico and S. lyrata, n. sp. is recognized from Alberta, British Columbia, Idaho, Montana, Washington and Yukon Territory.
