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.pdf01850nas a2200145 4500008004100000245012600041210006900167260001200236300001200248490000700260520133800267100002501605700002501630856004901655 2007 eng d00aFungus gnats (Diptera: Bolitophilidae, Diadocidiidae, Ditomyiidae, Keroplatidae and Mycetophilidae) from Møre og Romsdal0 aFungus gnats Diptera Bolitophilidae Diadocidiidae Ditomyiidae Ke c12/2007 a147-1710 v543 a

Faunistic data on fungus gnats from the county of Møre og Romsdal in Norway are presented and all species known from the county are summarized in a checklist. Treatment of some 23000 specimens, collected with one Malaise trap and one window trap for a whole year each, resulted in the identification of 315 species from a single site at Jordalsgrend, Sunndal municipality. Material from three other localities in Møre og Romsdal and a few previously published records adds 42 species, bringing the total up to 357 species belonging to the families Bolitophilidae (11), Diadocidiidae (6), Ditomyiidae (2), Keroplatidae (11) and Mycetophilidae (327). Ten of the species are considered to be new to science and three species represented with single females could not be identified to species level. Records of 57 species are published for the first time from Norway, including three species that have been listed from Norway without any published records. The 34 species included in the Norwegian 2006 Red Data List are commented on. The high species diversity found at Jordalsgrend reveals a new picture when compared with other surveys in the Nordic region, and may have implications for future forest management, as boreal-oceanic, old-growth, deciduous forests are underrepresented in most conservation plans.

Eight species names previously published from Iceland are removed from the Icelandic fauna due to misidentifications. Three replaced names and 20 new species are added; viz. Allocotocera pulchella (Curtis, 1837), Sciophila hirta Meigen, 1818, S. parviareolata Santos Abreu, 1920, Boletina basalis (Meigen, 1818), B. gripha Dziedzicki, 1885, Leia fascipennis Meigen, 1818, Anatella sp., Brevicornu auriculatum (Edwards, 1925), B. verralli (Edwards, 1925), Exechia borealis Lundström, 1912 sp. restit., E. micans Lastovka & Matile, 1974, E. pectinivalva Stackelberg, 1948, E. pseudofestiva Lackschewitz, 1937, E. sp. A, Exechiopsis ligulata (Lundström, 1913), Rymosia speyae Chandler, 1994, Mycetophila marginata Winnertz, 1863, Phronia bicolor Dziedzicki, 1889, P. braueri Dziedzicki, 1889, P. taczanowskyi Dziedzicki, 1889, Trichonta atricauda (Zetterstedt, 1852), T. terminalis (Walker, 1856) and Zygomyia pseudohumeralis Caspers, 1980.
The known fauna now comprises 41 species in 19 genera. Keys to genera and males of all species are provided. Females are associated to males and keyed for all species except for species belonging to genera Anatella Winnertz, Brevicornu Marshall and Sciophila Meigen. One male Exechia with rather peculiar but mal-developed terminalia could not be placed in any known species. Hence, it is figured and briefly described here, but left without a scientific name until more material is discovered. Exechia borealis is figured and reinstated as a separate species based on studies of Finnish type material and selection of a lectotype. To confirm the identity of Macrocera nigropicea Lundström, 1906 the Finnish holotype has been studied and compared with the closely related M. maculata Meigen, 1818.
Estimates of the total species richness in Iceland varies between 44 and 52. The Icelandic fauna of fungus gnats is discussed in the context of its relationship to the wider Holarctic fauna, especially to that of the adjacent parts of NW Europe. There is a strong affinity with the rest of NW Europe and a high proportion of the Icelandic species show a Holarctic, seemingly circumpolar distribution. The fauna of fungus gnats in Iceland is regarded to be entirely postglacial in origin. Thus, the dominance of species in the subfamily Mycetophilinae indicates that they are a successful group in the high boreal and arctic regions with a great dispersion potential. The main limiting factor for the diversity of fungus gnats on Iceland is probably lack of highly developed forest environments

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 (Lundström, 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.

Recent studies have not shed much light on the intergeneric relationship within the tribe. Here the first attempt to resolve the phylogeny of the tribe Exechiini using molecular markers is presented. The nuclear 18S and the mitochondrial 16S, and cytochrome oxidase subunit I (COI) genes were successfully sequenced for 20 species representing 15 Exechiini genera and five outgroup genera. Bayesian, maximum parsimony and maximum likelihood analyses revealed basically congruent tree topologies and the monophyly of Exechiini, including the genus Cordyla, is confirmed. The molecular data corroborate previous morphological studies in several aspects. Cordyla is found in a basal clade together with Brachypeza, Pseudorymosia and Stigmatomeria. The splitting of the genera Allodiopsis s.l. and Brevicornu s.l. as well as the sistergroup relationship of Exechia and Exechiopsis is also supported. The limited phylogenetic information provided by morphological characters is mirrored in the limited resolution of the molecular markers used in this study. Short internal and long-terminal branches obtained may indicate a rapid radiation of the Exechiini genera during a short evolutionary period.1 aRindal, Eirik1 aSøli, Geir, E.
