Abstract

Two Nearctic species of Heterotanytarsus are described: Heterotanytarsus perennis n.sp. from male imagines, pupae, and fourth-instar larvae; H. nudalus n.sp. from imagines and pupae. These are the first published records and descriptions of Nearctic species of this genus.Keys are given for male imagines and pupae of the four Nearctic and Palaearctic species of the genus.Heterotanytarsus perennis has been recorded only from Marion Lake, British Columbia. The species is univoltine. Heterotanytarsus nudalus has been recorded only from Lake 192, Freshwater Institute Experimental Lake Area, Kenora, Ont. This species is bivoltine. A larva of Heterotanytarsus has been found in Sawley Lake, Algonquin Park, Ont. The findings, together with the absence of the characteristic larva from numerous other localities, indicate both species as northern oligotrophic members of chironomid communities.
