DISTRIBUTION. Holarctic. A cold-loving species. North of the Arctic circle in lowlands, in Russian Altai-Sayan Mts and Mongolian Khentii Mts it is distributed much further to the south, till 50 ° N. Other authors reported more southern records for E. divisa , for example, Rozkosny (1987) mentions Karelia and Omsk regions of Russia. We formulate the distribution of the species on the basis of only those specimens that we have examined ourselves and for the identification of which we are responsible .
