Distribution

Palaearctic. Boletina borealis (Fig. 11a) is formely recorded in Europe from the northern parts of Russia (Novaya Zemlya, Karelia, Zaitzev 1994, Polevoi 2013a), northern Sweden (provinces JÄ, ÅS,LY,LU, Kjaerandsen et al. 2007), Norway (Finnmark, Søli and Rindal 2012), and also from mountainous areas of Austria, Germany, Italy and Poland ( Plassmann 1984, Chandler 2004), indicating a boreal–mountainous to arctic distribution.

Ecology

The species is rather numerous in Malaise trap cathces collected from Finnish Lapland in June, less so during July. One of the most common fungus gnats in riparian woodlands and aapamires. Larval ecology is unknown.

Taxon discussion

Boletina borealis is very close to B. intermedia Lundström. These two taxa can reliably be distinguished if internal structures, especially parameres, of the male hypopygium are studied (see Fig. 11). In B. borealis , apices of parameres are thin and curved (Fig. 11a), whereas in B. intermedia these are stout and spear-shaped (Fig. 11b). It is likely that B. intermedia has been overlooked in faunistic surveys, but the material studied here suggests that B. borealis is rather common in North Finland, whereas B. intermedia is locally less abundant and has a smaller area of occupancy. Another species, perhaps an undescribed species close to B. hymenophalloides Sasakawa & Kimura, 1974, is superficially similar to B. borealis and B. intermedia . However, aedeagus of this species is surrounded by a weakly sclerotized membrane and additional differences are present in the sturucture of sternal submedian appendages and parameres. This species, collected from NE Lapland, will be described elsewhere.
