Background
The subfamily Gnoristinae is one of the most diverse and taxonomically difficult subfamilies of Mycetophilidae, with new species and genera being described almost every year from various parts of the world. Through inventories of fungus gnats in the Nordic Region and Russia, a genus and species new to science was discovered, yet with links back to an illustration made by the late French entomologist Lo\ïc Matile in the 1980s. DNA barcoding aligned it with yet another species new to science, distributed across Canada and documented through The Barcode of Life Data System (BOLD) by Paul D. N. Hebert and colleagues at the BOLD team.

New information
The new Holarctic genus, Coelosynapha gen. n. is described, consisting of two new species, the Palaearctic Coelosynapha loici sp. n. and the Nearctic Coelosynapha heberti sp. n. DNA-barcodes assign the two new species to distinctly separated (8.27\% p-distance) Barcode Index Numbers (BINs) which are most closely aligned to unidentified species of Mycetophilidae from South Australia and Costa Rica on BOLD. The new genus shows morphological characteristics in between the two Holarctic genera Coelosia Winnertz, 1864 and Synapha Meigen, 1818 and further shows affinity to the southern continents genus Austrosynapha Tonnoir, 1929. The Palaearctic Coelosynapha loici sp. n., for which habitat requirements are best documented, is largely restricted to pristine, old-growth conifer (mostly spruce, Picea abies ssp. obovata) forests within the boreal vegetation zone, although it is also recorded from hummock tundra along the Anadyr River in Far East Russia.

New data on four poorly known species of the genus Leia Meigen (L. nigricornis van Duzee, L. flavipennis Laštovka \& Matile, L. iturupensis Zaitzev and L. rufiptera Ostroverkhova) are presented. Detailed redescriptions and terminalia figures are provided. Leia nigricornis is reported for the first time from the Palaearctic region and L. automnala Ostroverkhova \& Grishina is found to be a junior synonym of L. flavipennis. A variation in the male terminalia of L. bimaculata Meigen is illustrated, based on specimens from several European countries.

The first modern Swedish checklist of fungus gnats of the families Bolitophilidae, Diadocidiidae, Ditomyiidae, Keroplatidae and Mycetophilidae is presented. The checklist results from a comprehensive literature research as well as treatment of a considerable determined and undetermined material from Swedish museum collections and recent material from several sources. To get better grounds for judging many old and doubtful records from Sweden, a nearly complete review of fungus gnats from the J. W. Zetterstedt collection at the Museum of Zoology in Lund has been undertaken and identifications corrected where needed. In order to preserve nomenclatural stability three species names are reinstated, all with priority over junior synonyms, viz. Orfelia lugubris (Zetterstedt, 1851) comb. n. = Orfelia tristis (Lundstr\öm, 1911) syn. n., Ectrepesthoneura ovata Ostroverkhova, 1977 = Ectrepesthoneura bucera Plassmann, 1980 syn. n., and Dynatosoma thoracicum (Zetterstedt, 1838) sens. auct. nec Zaitzev = Dynatosoma norwegiense Zaitzev \& \Økland, 1994 syn. n. We further find the holotype of Mycetophila grisea Zetterstedt, 1852 to be identical to Mycetophila perpallida Chandler, 1993, but retain Mycetophila perpallida pending a review of other possible synonyms with precedence. Ectrepesthoneura pubescens (Zetterstedt, 1860) is found to be a synonym of Ectrepesthoneura unifurcata (Zetterstedt, 1860) comb. n. syn. n. where the first name is retained as valid due to page priority. Four names described by Zetterstedt remain nom. dub., viz.: Mycomya diluta (Zetterstedt, 1860), Mycomya (Mycomya) notata (Zetterstedt, 1860), Brevicornu fusculum (Zetterstedt, 1838), and Brevicornu obscurellum (Zetterstedt, 1838) comb. n. Stigmatomeria obscura (Winnertz, 1863) sp. restit. is found to be a distinct species separate from Stigmatomeria crassicornis (Stannius, 1831). New combinations are suggested for Exechia praedita Plassmann, 1976 = Exechiopsis (Xenexechia) praedita (Plassmann, 1976) comb. n., and for Rhymosia pectinacea Ostroverkhova, 1979 = Pseudexechia pectinacea (Ostroverkhova, 1979) comb. n. Having removed 17 published species names with doubtful or wrong records (listed at the end) we find that the published sources comprise altogether 585 species. 137 species are reported for the first time in Sweden, bringing the total up to 722. Additional 36 species considered to be new to science are mentioned for completeness, but will be further presented and described elsewhere. Hence, at present the known fauna (including claimed undescribed species) comprises 758 species in 83 genera; 25 species of the family Bolitophilidae, 5 of the family Diadocidiidae, 3 of the family Ditomyiidae, 45 of the family Keroplatidae, 679 of the family Mycetophilidae and 1 in the unplaced genus Sciarosoma Chandler. For each species a full account of published Swedish sources with pagination, all synonyms used in Sweden and the currently known distribution in the Swedish provinces as well as the known world distribution is given. The Swedish species of fungus gnats are generally very widespread: 47\% being widespread in Europe, 43\% being distributed in the Eastern Palaearctic Region, and 25\% having a Holarctic distribution. We find significantly higher species richness in the boreal forests of northern Sweden, but only 3\% of the species so far described are known only from the Nordic biogeographical region.

This study of mycetophilids was based on trap samples from 15 oak-dominated sites in the boreonemoral zone of southern Sweden. Species richness and composition were analysed in relation to environmental variables at a local and at larger scales (multiple regression), and compared to results from similar studies in spruce-dominated sites in the boreal zone of Norway (PCA and two-sample t tests). Regressions showing a dominance of regional factors over local in-site variables agree with species-richness models assuming that local communities most often are unsaturated. Precipitation (inter-correlated with elevation) was the strongest factor for explaining the variation in species-richness, which is consistent with previous results indicating that mycetophilids are disfavoured by drought. In addition to precipitation, the area of mixed forest with high biodiversity values (woodland key habitats and protected areas) was a positive factor for species-richness, probably because such habitats combine elements of both coniferous and deciduous forests. PCA ordination revealed a clear separation of the species composition between boreal and boreonemoral forests. Species-richness in boreal forest was significantly higher than in boreonemoral forest, indicating a preference for boreal habitats in many of the species. For mycetophilids and other drought-sensitive insects, it is suggested that (partial) cutting in some dense successional oak stands should be avoided, and that some invading spruces should be tolerated.
