Diagnosis.

Philonthus lindrothi can be distinguished fromnortheastern congeners other than Philonthus pseudolodes Smetana 1996 by the combination of: pronotum with five punctures in the dorsal row on at least one side; head with hind angles present but rounded; tergite eight not emarginate in either sex; elytra without distinct markings on the disc; hind tarsus with first segment shorter than last segment; antennae with basal segments not distinctly paler than others and with segments seven and eight elongate. Males can be readily separated from Philonthus pseudolodes by the notch in sternite eight not continuing as a grove towards its base ( Smetana 1995).

This widespread species was previously known from Alaska, Alberta, Arizona, British Columbia, California, Colorado, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Manitoba, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Brunswick, Newfoundland, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Northwest Territories, Nova Scotia, Ohio, Ontario, Oregon, Pennsylvania, Québec, Rhode Island, Saskatchewan, South Dakota, Vermont, Washington, and Wisconsin ( Smetana 1995). Herein we newly record it from Prince Edward Island (Map 32). Philonthus lindrothi is an extremely common hygrophilous species that occasionally visits lights ( Smetana 1995).
