Distribution.

This species ranges from Newfoundland (Lindroth 1955a: 64) to east-central Alaska (Lindroth 1963b: 349), south at least to Sonoma County in western California (Casey, 1918: 96, as Bembidion nubiferum ), northeastern New Mexico (Mora County, Foster F. Purrington pers. comm. 2012), east-central Ohio (Usis and MacLean 1998: 67), the Adirondack Mountains in New York (Notman 1928: 217, as Bembidion arcuatum ), and southeastern Maine (Washington County, CNC); also known from eastern Siberia (Marggi et al. 2003: 250). The records from “Massachusetts” (Bousquet and Larochelle 1993: 139), “Pennsylvania,” and "West Virginia" (Hamilton 1894a: 8, as Bembidion dentellum ) need confirmation.
