S<\/span>\u00f8<span>li (at the Natural History Museum in Oslo, Norway) illustrations and a brief one-page description of a potential new fly genus, belonging to fungus gnats of the family Mycetophilidae, based on a single specimen collected in Finland. Matile posed a seeming simple question to S<\/span>\u00f8<span>li, \u201cHad this for years\u2026What do you think?\u201d Unable to do much with the scarce material, the specimen was shelved, twice, for even after more specimens were found in Finland in 2009 and sent to a specialist in the USA, no progress was made.<\/span><\/p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.6.5&#8243; hover_enabled=&#8221;0&#8243; sticky_enabled=&#8221;0&#8243;]<p><strong>Growth of research ties and a reference library<\/strong><\/p>\n<p><span>During this time, the popular and widespread use of DNA barcoding has led to an accumulation of a substantial volume of sequenced insects on the Barcode of Life Data (BOLD) system.\u00a0<\/span><span>More than 65,000 specimens belonging to the fly family Mycetophilidae have been successfully sequenced. Some 1,100 of them have public barcodes, although more than 2,400 different Barcode Index Numbers (BINs) are assigned, which indicates that the majority of the species still remain unidentified beyond the (sub)family level. <\/span><\/p>\n<p><span>In the Nordic region, strong scientific research ties grew during the early 2000s between the Swedish, Norwegian, and Finnish biodiversity information centres, taxonomy initiatives, and the<a href=\"http:\/\/www.norbol.org\/en\/\"> Norwegian Barcode of Life<\/a> (NorBOL) and <a href=\"https:\/\/www.finbol.org\/\">Finnish Barcode of Life<\/a> (FinBOL). These alliances are ensuring that the best taxonomic expertise is building up data in the reference library for local fauna on BOLD. Hence, the vast majority of some 6,500 DNA barcoded fungus gnats from the Nordic region have been identified to species level upon submission. The reference library is then painstakingly quality-checked and curated after barcodes and BINs are assigned. This has resulted in a high-quality reference library, now covering about 90 percent of up to 1,000 known Nordic species of the family.<\/span><\/p>\n<p><span>The reference library gives us entirely new opportunities through machine identification of insect samples. Examples range from expanded taxonomic studies on the larger Holarctic fauna as in this study, to ecological studies on how fungus gnats function in our boreal ecosystems, to more applied stakeholder science ranging from management of unprotected and protected areas to monitoring insect populations and the often claimed decrease in insect diversity caused by disturbances like commercial land use, pesticides from agriculture, and climate change.<\/span><\/p>[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner column_structure=&#8221;1_2,1_2&#8243; use_custom_gutter=&#8221;on&#8221; gutter_width=&#8221;2&#8243; make_equal=&#8221;on&#8221; _builder_version=&#8221;4.4.9&#8243; custom_padding=&#8221;||0px|||&#8221;][et_pb_column_inner type=&#8221;1_2&#8243; saved_specialty_column_type=&#8221;3_4&#8243; _builder_version=&#8221;4.4.9&#8243;][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/12\/Salmela_Fig2.png&#8221; title_text=&#8221;Attin\u00e1 Fig1 Map&#8221; _builder_version=&#8221;4.6.5&#8243;][\/et_pb_image][\/et_pb_column_inner][et_pb_column_inner type=&#8221;1_2&#8243; saved_specialty_column_type=&#8221;3_4&#8243; _builder_version=&#8221;4.4.9&#8243; custom_css_main_element=&#8221;margin:auto;&#8221;][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/12\/Salmela_Fig3.png&#8221; title_text=&#8221;Attin\u00e1 Fig1 Map&#8221; _builder_version=&#8221;4.6.5&#8243;][\/et_pb_image][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=&#8221;4.4.9&#8243; custom_padding=&#8221;12px||0px|||&#8221;][et_pb_column_inner saved_specialty_column_type=&#8221;3_4&#8243; _builder_version=&#8221;4.4.9&#8243;][et_pb_text _builder_version=&#8221;4.6.5&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221; custom_padding=&#8221;||0px|||&#8221; hover_enabled=&#8221;0&#8243; sticky_enabled=&#8221;0&#8243;]<p>Holotype of<span>\u00a0<\/span><i><span class=\"tn\"><span class=\"genus\" full-name=\"Coelosynapha\">Coelosynapha<\/span><span>\u00a0<\/span><span class=\"species\" full-name=\"loici\">loici<\/span><\/span><\/i><span>\u00a0<\/span>sp. n.
