Diagnosis. See Benick & Lohse (1974). Aedeagus and spermatheca: Fig. 155 in Strand & Vik (1964).

Discussion. The lectotype of At. nomadica represents a small specimen of At. graminicola , and falls within the range of intraspecific variation of At. graminicola in punctation, proportions of antennal segments and the shape of the spermatheca. The lectotype of At. lanei is similar to examined specimens of At. graminicola in external characters and in the shape of the spermatheca.

Lohse and Smetana (1985) argued that At. graminicola and At. granulata are closely related but different species, citing the difference in the shape of the aedeagus and spermatheca and in punctation of the pronotum and elytra. The proximal portion of the spermatheca in At. graminicola is variable and the difference between Figs. 5 and 7 in Lohse and Smetana (1985) is within the range of variability of this species. I was unable to confirm the difference between Palaearctic specimens of At. graminicola and Nearctic specimens. I consider At. granulata to be synonymous with At. graminicola .

Distribution. Atheta graminicola is a Holarctic species. In North America it is known from Canada (British Columbia, Yukon Territory, Northwest Territories, Alberta, Manitoba, Ontario, Québec, Labrador, Newfoundland) and the United States (Alaska and Oregon).
