Distribution

European. A poorly known and rarely collected Fennoscandian species (Fig. 9). The species was described by Zaitzev (in Zaitzev and Polevoi 1995), based on a holotype male collected from Kivach Nature Reserve, Russian Karelia. Recently, the species was observed from Alta in northern Norway ( Søli and Rindal 2012).

Ecology

Immature stages are unknown, but Brevicornu larvae are most likely associated with microfungi in dead wood and soil litter ( Jakovlev 2011). The species is presumably a forest-dwelling fungus gnat; at least, the Norwegian sampling site was a mixed forest ( Ekrem et al. 2012). The Finnish locality is a swampy birch forest in the subalpine ecoregion.
