Distribution

Holarctic. Described from North America ( Gagné 1981), later found in the Altai Mountains, western Siberia ( Zaitzev 2003). In Europe recorded so far only from Norway ( Økland and Zaitzev 1997, Søli and Rindal 2012) and Murmansk region of NW Russia ( Polevoi 2010). No former records from Finland; all findings reported here are from North Finland.

Ecology

Finnish collecting sites are old-growth boreal forests, mountain birch forests and a riparian forest. Immature stages are unknown.

Conservation

Red-listed in Norway (DD, Anonymous 2010, Gammelmo et al. 2010).
