Discussion. To clarify the status of Atheta altaica and At. picipennis , the types of both species were examined. The types of At. altaica correspond to the accepted concept of this species (e. g., Strand & Vik 1964; Lohse et al. 1990).

Distribution. Atheta altaica has a circumpolar distribution. In North America it is known from Alaska, Yukon Territory, Northwest Territories and Labrador ( Lohse et al. 1990).
