Distribution in Canada and Alaska.

AK, YT, NT, BC, AB, QC, NB ( Smetana 1995). Philonthus subvirescens is a Holarctic species with a mostly western distribution from Alaska and the Northwest Territories south to the mountains of California and east to New Mexico, with a significantly disjunct population in Quebec on the Gaspé Peninsula ( Smetana 1995). The presence of this species in northwestern New Brunswick indicates that this species has a somewhat wider distribution in easternmost Canada.
