New and poorly known Palaearctic fungus gnats (Diptera, Sciaroidea).
BACKGROUND
Fungus gnats (Sciaroidea) are a globally species rich group of lower Diptera. In Europe, Fennoscandian peninsula in particular holds a notable diversity, ca. 1000 species, of which 10 % are still unnamed. Fungus gnats are predominantly terrestrial insects, but some species dwell in wetland habitats.


CONCLUSIONS
Eight new fungus gnat species, belonging to the families Keroplatidae (Orfelia boreoalpinaSalmela sp.n.) and Mycetophilidae (Sciophila holopaineniSalmela sp.n.,S. curvataSalmela sp.n.,Boletina sasakawaiSalmela & Kolcsár sp.n.,B. norokorpiiSalmela & Kolcsár sp.n.,Phronia sompioSalmela sp.n.,P. reductaSalmela sp.n.,P. prolongataSalmela sp.n.), are described. Four of the species are known from Fennoscandia only whilst two are supposed to have boreo-alpine disjunct ranges, i.e. having populations in Fennoscandia and the Central European Alps. One of the species probably has a boreal range (Finnish Lapland and Central Siberia). Type material ofBoletina curtaSasakawa & Kimura from Japan was found to consist of two species, and a further species close to these taxa is described from Finland.Phronia elegantulaHackman is redescribed and reported for the first time from Norway. DNA barcodes are provided for the first time for five species.
