Comments.

Our collections are the first records for the eastern CAA. Aiken et al. (2007) reported the species in the CAA from a single collection on Victoria Island (Lambert s. n., CAN-52349). Argus (2007) mapped the species as occurring in the low Arctic from Alaska to western Hudson Bay, including southern Victoria Island, King William Island and the lower Boothia Peninsula. Our collections represent an eastern range extension of some 900 km for the species, with respect to the map in Argus (2007).
