Length 5 to 6 mm. Peritrechus species have only one or two small spines on the front femora. As in Scolopostethus, a pale spot is present at the sides of the pronotum, although this is not always obvious. P. geniculatus is similar to P. nubilus but the 3rd antennal segment is as thick, or thicker, than the 1st and the pronotum is more elongate. The markings on the upper surface are also usually slightly duller.
