Updated checklist of Norwegian Mycetophilidae (Diptera) with 92% DNA barcode reference coverage.

Abstract

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 Tromsø 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).
