Distribution.

This circumpolar species ranges from Iceland to eastern Siberia (Jaeger and Kataev 2003: 403) and from Alaska (Lindroth 1968: 876) to Greenland ( Böcher 1988: 14), south to southeastern Massachusetts (Cape Cod, CNC), central Iowa (Wickham 1911b: 8), central South Dakota (Kirk and Balsbaugh 1975: 32), the Sacramento Mountains in New Mexico (Fall and Cockerell 1907: 162), and the Baja California Peninsula (Horn 1894: 312). The records from southeastern New York (Notman 1928: 249) and “Pennsylvania” (Bousquet and Larochelle 1993: 227) need confirmation.
