Abstract
Themira athabasca n. sp. from Circle, Alaska is described, and a revised key to nearctic Themira is given. The sexual morphology and mating behavior of the sympatric arctic and midwestern U. S. species indicate that communities in these habitats demonstrate the parallel evolution of these characteristics. Sexual selection for mating efficiency is proposed as the evolutionary force responsible for the similarity of the communities.This publication has 0 references indexed in Scilit:
