The material was collected with Malaise traps, window traps and coloured pan traps at 15 sites in the years 1997-2003. The Tyresta forest suffered from a 450 ha area wild-fire in 1999, and about half (55%) of the samples originates from newly, partly heavily burnt wild-fire sites. Altogether 248 species are recorded, including 22 species new to Sweden, viz. Symmerus nobilis Lackschewitz, 1937, Orfelia unicolor (Staeger, 1840), Phthinia winnertzi Mik, 1869, Sciophila krysheni Polevoi, 2001, Sciophila modesta Zaitzev, 1982, Sciophila persubtilis Polevoi, 2001, Sciophila setosa Garrett, 1925, Boletina edwardsi Chandler, 1992, Gnoriste harcyniae von Roder, 1887, Allodia (Allodia) anglofennica Edwards, 1921, Allodia (Brachycampta) foliifera (Strobl, 1910), Anatella ankeli Plassmann, 1977, Exechiopsis (Xenexechia) perspicua (Johannsen, 1912), Synplasta pseudingeniosa Zaitzev, 1993, Mycetophila dziedzickii Chandler, 1977, Mycetophila gentilicia Zaitzev, 1999, Mycetophila lubomirskii Dziedzicki, 1884, Phronia distincta Hackman, 1970, Sceptonia regni Chandler, 1991, Sceptonia thaya Sevcik, 2004, Trichonta clavigera Lundstrom, 1913, and Trichonta subterminalis Zaitzev & Menzel, 1996. Five species (1 Diadocidia, 1 Docosia, 2 Cordyla and 1 Dynatosoma) are regarded as new to science and will be described elsewhere. The species richness and composition fits well the general picture of increasing species diversity towards north when compared with other surveys in the Nordic region. The material shows no significant difference between fire-sites and intact forest with respect to number of specimens caught, but the species composition is quite different. As expected, the highest number of species (185) was found at the undisturbed sites, and 43 species are significantly found to be avoiding the fire sites. Still, attraction of many fungus gnats to wild-fire sites is strongly indicated by a high number of species (151) captured there, of which 37 species are significantly over-represented at such sites. For 201 species (81%) the known larval habitat is given, showing that fungus gnats from Tyresta are dependant upon a rich biota of both epigeal and wood-growing fungi, and on decaying wood, particularly of deciduous trees.1 aJakovlev, Jevgeni1 aKjærandsen, Jostein1 aViklund, Bert uhttp://www.online-keys.net/sciaroidea/add01/Jakovlev_al_2008_fungus_gnats_from_tyresta.pdf02409nas a2200145 4500008004100000245007700041210006900118300001000187490000700197520187600204100002202080700002502102700002002127856011602147 2006 eng d00aSeventy species of fungus gnats new to Finland (Diptera: Mycetophilidae)0 aSeventy species of fungus gnats new to Finland Diptera Mycetophi a22-390 v113 aSeventy species of fungus gnats are reported as new to Finland. Additionally two species are confirmed, increasing the known Finnish fauna to 699 species. Eighteen of the species are also new to the Nordic region, viz.: Mycomya (Mycomya) livida (Dziedzicki, 1885); Neoempheria bimaculata (von Roser, 1840); Phthinia winnertzi Mik, 1869; Sciophila pseudoflexuosa Kurina, 1991; Sciophila setosa Garrett, 1925; Allodiopsis gracai Ševčík & Papp, 2003; Brevicornu arcticoides Caspers, 1985; Exechia pseudofestiva Lackschewitz, 1937; Exechia repandoides Caspers, 1984; Exechiopsis (Xenexechia) perspicua (Johannsen, 1912); Notolopha sibirica Zaitzev & Maximova, 2000; Pseudexechia canalicula (Johannsen, 1912); Dynatosoma silesiacum Ševčík, 2001; Mycetophila exstincta Loew, 1869; Mycetophila idonea Lastovka, 1972; Mycetophila triangularis Lundström, 1912; Sceptonia hamata Ševčík, 2004; Sceptonia thaya Ševčík, 2004. Three species are reported for the first time from the Palaearctic region, viz.: Sciophila setosa, Exechiopsis (Xenexechia) perspicua and Pseudexechia canalicula. The new records are based mainly on original material collected in southern Finland in 2003 - 2004. In addition the collections at the Finnish Museum of Natural History, Helsinki were re-examined for the genera Boletina (in part), Allodiopsis, Exechia, Exechiopsis, Myrosia, Notolopha, Rymosia and Synplasta. Detailed information on Finnish records as well as data on the general distribution and taxonomical notes are given for each species new to Finland.
