UNITED STATES: VA: Giles Co., Ripplemead, rte 460 at bridge, flood debris, berlese, 11 to 25-V-2008, A. Brunke (4). Diagnosis. Philonthus neonatus is separated from other northeastern Philonthus by the combination of: pronotum with six punctures in both dorsal rows; pronotum no more than vaguely narrowed anteriorly; elytra distinctly red and without dark markings; elytra with micropunctures between the regular punctures; abdominal segments paler apically. This species was previously known from Arkansas, District of Columbia, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri , New Hampshire, New Jersey, New York, Ontario, Pennsylvania, and Quebec ( Smetana 1995 ). Herein we newly record it from Virginia (Map 33). Philonthus neonatus is a hygrophilous species collected from debris along the margins of creeks, rivers and lakes ( Smetana 1995 ). Maps 33-36.
