Distribution. The range of this species extends from the Ungava Bay area (Larochelle 1975: Fig. 173) in northern Quebec to the Arctic Plains of Alaska (Lindroth 1963b: 329), south to east-central Utah (Grand County, UASM), southwestern Colorado (Elias 1987: 632), southern South Dakota (Kirk and Balsbaugh 1975: 18), and the Saint Lawrence River drainage in southern Quebec (Larochelle 1975: Fig. 173).
