Up to present 602 species and 65 genera of fungus gnats, family Mycetophilidae, are published from Norway. Extensive collecting supported by the Norwegian Biodiversity Information Centre (NBIC) over the eight last years, with special focus on insect fauna in northern Norway, has documented 240 additional species and 2 additional genera from Norway, of which 118 species are considered as new to science. Based on a thorough review of the species previously published from Norway, we have crossed out six species as misidentified. One new synonym is established: Boletina conformis Siebke, 1863 syn. n. = Boletina plana (Walker, 1856). Two species are restituated based on integrative studies including DNA barcodes. These are Ectrepesthoneura bucera Plassmann, 1980 sp. restit., found to be a distinct species separate from Ectrepesthoneura ovata Ostroverkhova, 1977, and Trichonta trifida Lundstrom, 1909 sp. restit., found to be a distinct species separate from Trichonta vulcani (Dziedzicki, 1889). The updated, validated A-checklist includes 821 species of which 703 (86\%) refer to formally described species and 118 (14\%) to potentially undescribed species, referred to by their interim names as used on BOLD and in our databases. All species are documented with specimens in the museum collections at either Troms\ø University Museum (TMU, 781 species, 95\%) and/or the Natural History Museum in Oslo (NHMO, 382 species, 47\%). Another 14 published species are transferred to a B-checklist with currently unvalidated species, as we fail to recover voucher representatives. Supported by the Norwegian Barcode of Life (NorBOL) network, we have DNA barcoded as many species as possible contributing to the reference library on The Barcode of Life Project (BOLD). Hence, 756 (92\%) of the validated Norwegian species are currently documented with DNA barcodes and assigned Barcode Index Numbers (BINs) on BOLD, including the majority of the species considered new to science based on morphology (103 species, 87\% of the 118). The checklist, is kept in a short format giving the published species names or interim names as used on BOLD and in our databases, depository information, assigned BINs with indications of discordance, and finally their (2015) Red List status in Norway. An accompanying dataset containing recording details and distribution of all new records from Norway of described species, is published on GBIF and on Norway\’s Species Map Service (Artskart).

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.

We provide the first molecular phylogeny of Keroplatidae and Lygistorrhinidae, families of fungus gnats (Diptera: Bibionomorpha: Sciaroidea). Phylogenies reconstructed by Maximum Likelihood and Bayesian methods, based on four nuclear and four mitochondrial gene markers (5106 base pairs) sequenced for 75 genera and 105 species, show Keroplatidae as monophyletic only with the family Lygistorrhinidae included, herewith treated as the subfamily Lygistorrhininae stat. nov. The subfamily Arachnocampinae is retained in the family, although lowering its overall support. An early branching clade, comprising species of Platyura Meigen, 1803 and Paleoplatyura melanderi Fisher, 1941, forms subfamily Platyurinae Loew, 1850 stat. nov. The subfamilies Sciarokeroplatinae and Macrocerinae grouped together with three genera considered here as Keroplatidae incertae sedis. Subfamily Lygistorrhininae forms a sister clade to subfamily Keroplatinae, both retained monophyletic with high support. The traditional division of the subfamily Keroplatinae into the tribes Orfeliini and Keroplatini appears as outdated, resting largely on adaptive characters prone to parallel evolution. We find support for an alternative tribe corresponding to the Cloeophoromyia\–Asindulum genus group, but a tribal reclassification of the Keroplatinae is left for future studies. The genus Heteropterna Skuse, 1888 is considered as identical with Ctenoceridion Matile, 1972 syn. nov.
