Distribution.

This Holarctic species ranges from Novaya Zemlya in the Arctic Ocean off the coast of European Russia east to Franklin Bay on the coast of Northwest Territories, south in the Nearctic Region to central Northwest Territories and Umnak Island in the Aleutian Islands [see Ball 1963: Fig. 2]. Fossil remnants of this species, dated between about 16,700 and 20,530 years B.P., have been unearthed in northeastern and southeastern Iowa (Schwert 1992: 77; Baker et al. 1986: 96; Woodman et al. 1996: 17); others, older than 33,000 years B.P., have been found in southwestern Ontario (Warner et al. 1988: 37).
