Diagnosis. See Lohse et al. 1990.
Discussion. The types of At. caviceps and Boreophilia chillcotti are identical in external characters and in the shape of the aedeagus, including the sclerites of the internal sac.
Atheta blatchleyi has the pronotal setation pattern of Type II. The holotype of Boreophilia chillcotti has damaged setation on the pronotum, and that explains why Lohse (Lohse et al. 1990) could not describe the setation of that species correctly. Based on the pronotal setation pattern and the shape of the aedeagus and spermatheca, this species cannot be placed in Boreophilia. Pending generic revision of Athetini, the species is placed in Atheta.
Distribution. Atheta blatchleyi is a transnearctic species but its distribution is poorly documented. It is known from the United States (Alaska and Indiana) and Canada (Yukon Territory, Northwest Territories, Manitoba and New Brunswick).
