Bembidion sordidum (Kirby, 1837)

Peryphus sordidus Kirby, 1837: 52. Type locality: "Lat. 54° [= along North Saskatchewan River]" (original citation), restricted to "Edmonton, Al[ber]ta" by Lindroth (1963b: 328). Holotype [by monotypy] in BMNH (Lindroth 1953b: 176).

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). The record from “Michigan” (Bousquet and Larochelle 1993: 137) needs confirmation. Fossil remnants, dated from about 10,400 and 21,500 years B.P., have been unearthed in eastern Minnesota, northeastern Wisconsin, Iowa, northern Illinois (Schwert 1992: 77), northeastern Pennsylvania (Barnosky et al. 1988: 178), and Cape Breton Island in Nova Scotia (Miller 1997: 250).
