Distribution

Holarctic, known from arctic Russia (Kanin Peninsula, as Brachycampta arctica , Lundström and Frey 1913), Russian Karelia and Murmansk region ( Polevoi 2000, Polevoi 2010), Ireland ( Chandler 1977), Central Europe ( Chandler 2004) and USA ( Zaitzev 1988). In the Nordic countries recorded from Sweden and Norway ( Kjaerandsen 2012). Perhaps a boreo-montane species ( Kjaerandsen et al. 2007). New for Finland.

Ecology

Finnish sampling localities are headwater streams surrounded by pristine or seminatural boreal forests. Immature stages are unknown. In their larval habitats, Brevicornu do not resemble closely related species of Allodia . At least some Brevicornu species develop in dead wood and in soil litter, feeding probably on microfungi ( Jakovlev 2011a).
