Distribution

Palaearctic. Described from Finland ( Lundström 1912a), later recorded from Ural and Altai ( Zaitzev 1994) and from Europe, chiefly from northern areas: Norway, Sweden, Finland, NW Russia, Baltic countries, Germany ( Chandler 2004, Kjaerandsen et al. 2007). New to the Republic of Karelia.

Ecology

The species is very rare. There are only four Finnish records, one of these was made more than a hundred years ago ( Lundström 1912b, SW Finland, Kaarina, Kuusisto). The only recent finding is from a headwater stream surrounded by a spruce mire (Central Finland, Äänekoski). The Karelian specimen was collected at the edge of a small settlement near a herb-rich aspen dominated forest. Immature stages are unknown, other species of the genus have been reared from soil, clumps of turf, rotting wood and cave walls and are considered predaceous ( Falk and Chandler 2005, Ševčík and Roháček 2008, Jakovlev 2012).

Conservation

Red-listed in Finland (NT, Penttinen et al. 2010) and Norway (VU, Anonymous 2010, Gammelmo et al. 2010).
