Comments.

This species was described recently from three localities on southern Banks Island, Northwest Territories, and one locality in northern Alaska ( Consaul et al. 2008). Saarela et al. (2013a) reported two collections from the lower Brock River on mainland Northwest Territories. Here we report six new localities for the species from southwestern Victoria Island-the first records for this island and for Nunavut, expanding the species’ range eastwards in the CAA.
