Material examined: several hundreds workers and dozens of queens and males from the whole

Palaearctic Region.

Distribution. The boreal zone of Holarctic, the mountains of Southern Europe, the Caucasus, Tien-Shan.

Ecology. This species is most abundant in dry and lighted coniferous forests with scarce undergrowth, it reaches to the north the Forest-Tundra zone. It also can be found in open habitats, ranging from moist peat bogs to xerothermal grasslands. Nests are built (depending on habitat) in rotten logs or stumps, in fallen branches, under bark and, more rarely, under stones or in rock crevices, also under moss; in bogs they are found in peat.
