Description
Summary:Rheocricotopus (Rheocricotopus) reduncusoides sp. n. is described from Bathurst Island, Nunavut, Canada. Its discovery was made while curating and examining specimens deposited by H. V. Danks in 1969 at the Canadian National Collection in Ottawa, Canada. We also report the first Canadian record of Parametriocnemus hamatus (Johannsen, 1934) from Québec, based on previously unsorted material deposited at the Canadian National Collection. In this paper we provide distributional records of the Nearctic species of Rheocricotopus Thienemann and Harnisch and Parametriocnemus Goetghebuer, and present a key to the Nearctic adult males of these genera.
