Propsilocerus Kieffer (Diptera: Chironomidae) from the Nearctic

Abstract

Larvae of the chironomid genus Propsilocerus Kieffer (Diptera: Chironomidae), known from the Palaearctic region and from subfossil larval head capsules in North America, have been found living in remote British Columbia, Canada. We review the morphology and ecology of the taxon in North America, and report and interpret the subfossil occurrences. Although the species appears to be undescribed, we refrain from a formal taxonomic description based on the larva alone pending discovery of the full life history. Show more
