Distribution; world
A boreal species in Europe, with the centre of the range lying well to the east in Russia. The most western collections are from the region of Petrozavodsk, near Lake Onega, in E. Karelia (Russia) (Pekkarinen et al., 1981). From the map drawn by Tkalcu (1967), we can see that there were hardly more observations west of the Ural. Krüger (1956) mentions a few places in the Perm region. The species is also known from the regions of Moscow, Ivanovo, Kirov, Ul'yanovsk and Kaza:
