Type locality: "Eagle River [Keweenaw County, Michigan], lacus Superioris" (original citation). One syntype in MCZ [# 5489]. Monillipatrobus punctatus Hatch, 1933c: 118. Type locality: "Seattle [King County], Wash[ington]" (original citation). Holotype (♂) in USNM. Synonymy established by Hatch (1935: 118). Distribution. This species is known from scattered localities from the Lac Saint-Jean area in Quebec (Larochelle 1975: 99) to Vancouver Island, north to the Skeena River in northwestern British Columbia (Lindroth 1961a: 176), south to the San Gabriel and San Bernardino Mountains in southern California (Noonan 1967: 92), southern Arizona (McCleve 1975: 176), southwestern New Mexico (Grant County, USNM), and the upper peninsula of Michigan along Lake Superior (LeConte 1846a: 154).

This species is widely distributed west of the Rocky Mountains where it is usually found under the bark of relatively large coniferous trees. It is also found within the boreal regions east of the Rockies but is very rarely collected there. This species belongs to the same tribe as Nomius pygmaeus but unlike that species, the adults do not emit an unpleasant smell.
