In this study, we use low-coverage shotgun sequencing of genomic DNA, commonly referred to as genome skimming, to investigate the phylogenetic relationships of the fungus gnat genus Allodia Winnertz (Mycetophilidae, Mycetophilinae, Exechiini). Nineteen specimens, representing 16 in-group and three outgroup taxa, were successfully sequenced and molecular markers of both mitochondrial and nuclear origin were retrieved. The phylogenetic analyses of 13 protein-coding mitochondrial genes, two ribosomal mitochondrial genes and the nuclear ribosomal 18S and 28S strongly support the monophyly of its two subgenera Allodia s.s. and Brachycampta. Complete mitochondrial genomes of 15 species were assembled, which enables further comparisons with the mitochondrial genomes of other Diptera. Overall, the methodology used in this study proved successful and promising for other dipteran groups. In addition to the phylogenetic reconstruction, the morphological characters previously used to separate the two subgenera were evaluated and re-examined. Together with the composite structure of the male genitalia, we consider details of the scutal bristles appropriate for separating the two groups. Based on the achieved results, we reinstate Brachycampta stat. rev. as a separate genus.

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).

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 Loïc 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.

An extensive collection of fungus gnats from Nepal and Bhutan, deposited at Kyushu University Museum in Japan, has been examined and revealed nine species of Allodia Winnertz, 1864 new to science: Allodia caligata Magnussen, sp. n., A. dibolia Magnussen, sp. n., A. shimai Magnussen, sp. n., A. spathulata Magnussen, sp. n., A. horologia Magnussen, sp. n., A. himalayensis Magnussen, sp. n., A. nepalensis Magnussen, sp. n., A. thudamensis Magnussen, sp. n., and A. scalprata Magnussen, sp. n. All specimens were collected at high altitudes in the central and eastern Himalayas. The species all belong to the subgenus Allodia s. str. and constitute the first records of the genus Allodia in Nepal and Bhutan. Brevicornu nigrofasciatum (Brunetti, 1912) comb. n., originally described from northern India, is transferred from Allodia based on the original description. A key for the identification of the new species is provided.

Based on a study of the characters of the male genitalia in specimens from various countries, it is reconfirmed that M. unifurcata is the only species of Manota WILLISTON in Europe. Its geographic distribution is reviewed, and is augmented by new records from Germany and the first records from Sweden. The relationships of M. unifurcata to other Manota species are discussed. It appears that the species is rather isolated from other Manota in terms of both morphology and geographic distribution. The presence of a male hind tibial organ, which is described here, is a synapomorphous character shown by at least 4 of the 5 East Palaearctic species of Manota. These species and several Oriental Manota, for which presence or absence of the tibial organ is unknown, have several male genitalia characters in common, a fact that indicates their close relationships. Manota ibanezi HIPPA & HUERTA, 2009 from Mexico is shown to occur also in the north-eastern United States (Maine and New York). These are the first records of a named Manota species from the Nearctic Region. Possible explanations for the rarity of Manota in both North America and Europe are discussed.

Molecular studies have strongly indicated that this group forms a monophyletic sister-group to a clade consisting of all other Boletina, Coelosia and Gnoriste, and its monophyly is supported by morphological data as well. The new genus includes the following species: Katatopygia antoma (Garrett, 1924), comb. n., Katatopygia antica (Garrett, 1924), comb. n., Katatopygia erythropyga (Holmgren, 1883), comb. n., Katatopygia hissarica (Zaitzev & Polevoi, 2002), comb. n., Katatopygia magna (Garrett, 1925), comb. n., Katatopygia laticauda (Saigusa, 1968), comb. n., Katatopygia neoerythropyga (Zaitzev & Polevoi, 2002), comb. n. and Katatopygia sahlbergi (Lundström, 1906), comb. n., all transferred from Boletina. K. sahlbergi is found to be a senior synonym of Boletina punctus Garrett, 1925, syn. n. A phylogeny based on morphological data and using parsimony analysis yielded four most parsimonious trees where the new genus is retrieved as monophyletic with high support. Katatopygia neoerythropyga is found to be the sister-taxon to all other species that form two clades, one with K. sahlbergi-like species and one with K. erythropyga-like species. A key to males of Katatopygia is provided.

The systematics within the genus has gained little attention and this is a first attempt to shed some light over the systematics of Boletina and to test the segregation of the genera Saigusaia and Aglaomyia from Boletina. The nuclear marker 28S and mitochondrial 16S, COI and CytB were amplified and sequenced for 23 taxa that were analysed separately and together with a broad sample of outgroup taxa obtained from GenBank, where also 18S sequences were added. Phylogenies were estimated using maximum likelihood, Bayesian inference and parsimony. We strengthen the hypothesized sister-group relationship between Docosia and Boletina, but the genus Boletina as currently delimited appears to be paraphyletic and nested in a clade together with Aglaomyia, Coelosia and Gnoriste. The genus Saigusaia, on the other hand, seems to be well separated from Boletina. The Boletina erythropyga species group is consistently found as a distinct basal clade within Boletina s.l. The results obtained are otherwise ambiguous both for the taxa in focus and in some analyses globally with a statistically supported total breakdown of the traditional higher classification into tribes, subfamilies and even families. Interestingly, this breakdown almost disappeared when additional 18S sequences were added.

Janzen A1 - Kjærandsen, Jostein SP - 668 EP - 673 AB - Color patterns play central roles in the behavior of insects, and are important traits for taxonomic studies. Here we report striking and stable structural color patterns—wing interference patterns (WIPs)—in the transparent wings of small Hymenoptera and Diptera, patterns that have been largely overlooked by biologists. These extremely thin wings reflect vivid color patterns caused by thin film interference. The visibility of these patterns is affected by the way the insects display their wings against various backgrounds with different light properties. The specific color sequence displayed lacks pure red and matches the color vision of most insects, strongly suggesting that the biological significance of WIPs lies in visual signaling. Taxon-specific color patterns are formed by uneven membrane thickness, pigmentation, venation, and hair placement. The optically refracted pattern is also stabilized by microstructures of the wing such as membrane corrugations and spherical cell structures that reinforce the pattern and make it essentially noniridescent over a large range of light incidences. WIPs can be applied to map the micromorphology of wings through direct observation and are useful in several fields of biology. We demonstrate their usefulness as identification patterns to solve cases of cryptic species complexes in tiny parasitic wasps, and indicate their potentials for research on the genetic control of wing development through direct links between the transregulatory wing landscape and interference patterns we observe in Drosophila model species. Some species display sexually dimorphic WIPs, suggesting sexual selection as one of the driving forces for their evolution.

The genus Manota is recorded from Japan for the first time. Three new species, Manota satoyamanis, Manota indahae and Manota tunoae spp. nov., are described, based on specimens collected in an ecological sampling program of arthropods in the "satoyama" landscape of Ishikawa Prefecture. "Satoyama" represents the traditional rural landscape of Japan, which is characterized by a mosaic of secondary forests, plantations, ponds and rice paddy fields. The new species raise the number of Palearctic Manota species from five to eight.

We find that the original type species assignment for Urytalpa (Platyura ochracea Meigen, 1818) is based on a misidentification, and in order to stabilize the nomenclature we therefore select a new type species, Urytalpa dorsalis (Staeger, 1840), sp. restit.

The 25 currently known species of Pseudexechia are tentatively grouped into four species groups that are characterized mainly by structures of the male terminalia: the canalicula group(Holarctic), the longistylus group (Afrotropical) the trisignata group (Holarctic and Oriental), and the trivittata group (Holarctic and Oriental). The ten European species of Pseudexechia are then revised, of which one, Pseudexechia tuomikoskii sp. n., is described as new to science. All males and nine associated females are keyed, measured, described and illustrated. A principal component analysis of 59 morphometric measurements failed to give a clear separation of the different species and species groups. Except for overall size and some diffuse differences in flagellomere and tarsus lengths the present study also failed to reveal morphometric characters that are clearly taxonomically informative, and species identity must rest primarily on structural differences in the terminalia with aid of coloration patterns. Given as ratios, however, some measurements, like the wing vein R4+5 bending index and the length to width ratio of clypeus, appear to be informative at species group level.

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.

The four known species of Tarnania Tuomikoski are reviewed, viz. T dziedzickii (Edwards, 1941), T. fenestralis (Meigen, 1818), T. nemoralis (Edwards, 1941), and T. tarnanii (Dziedzicki, 1910). Males and females are re-described, photographed and their terminalia figured. An attempt is made to homologize and name specific substructures of the male gonostylus, widely recognizable within the tribe Exechiini. A phylogenetic analysis of the Tarnania species, including representatives of the six other genera of the Rymosia s. lat. genus group, strengthens the view that Tarnania is monophyletic. Tarnania is supported by six unambiguous character changes of which three are considered to be unique synapomorphies, viz. 1) lower parts of metepisternum and metepimeron covered with campaniform sensilla; 2) hind tibia with several curved bristles posterodorsally, placed irregularly in more than one row; and 3) anterior branch of male gonostylus forming an elongated, bifurcated lobe. The most parsimonious hypothesis for relationships among the species of Tarnania is ((T tarnanii + T nemoralis) + (T dziedzickii + T fenestralis)). The practice of regarding the genera of the Rymosia s. lat. genus group as an assemblage of plesiomorphic genera is also supported, the most parsimonious hypothesis for relationships among them being (Notolopha (Allodiopsis (Myrosia (Synplasta (Tarnania + (Rymosia + Pseudorymosia)))))). Tarnania is most diverse in northwestern Europe, with all four species known from Norway, Sweden, Great Britain, Belgium, Germany, Switzerland, and France. T dziedzickii extends its distribution southwards to include the North African and the Near East Regions. T. fenestralis is widely distributed in the western Palaearctic Region and extends its distribution eastwards to the eastern Palaearctic region. Only T. tarnanii displays a wide Holarctic distribution including most of Russia, Alaska, Canada and Greenland.

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.

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.

Pseudexechia parallela (Edwards, 1925) is redescribed and illustrated. Based on study of types and new material Pseudexechia parallela (Edwards, 1925) is considered to be a senior synonym of P. hamulata (Lackschewitz, 1937) syn. n. Pseudexechia parallela is reported from Sweden, Kamtschatka, Russia and Minnesota, U.S.A. for the first time, thus expanding its known range from Europe to a wide Holarctic distribution. A new allied species, Pseudexechia monica sp. n., is described and illustrated based on males from Wales in Great Britain.

E. A1 - Kjærandsen, Jostein A1 - Bachmann, Lutz SP - 327 EP - 335 AB - The phylogenetic relationships within the fungus gnat tribe Exechiini have been left unattended for many years. 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.

Some 20 000 specimens belonging to 80 species in 18 families were recorded. Mycetophilidae (95.0%), Culicidae (3.2%) and Heleomyzidae (1.3%), dominated. With the exception of Speolepta leptogaster (Winnertz, 1863) (Mycetophilidae), a possible troglophile, all species must be regarded as trogloxenes, most of them habitual trogloxenes inhabiting cave systems for hibernation. Some differences regarding species composition in different cave systems and between western and eastern Norway were demonstrated. Seasonal occurrence and sex-ratios reflect different life cycle strategies and seasonal adaptations among the habitual trogloxenes: hibernators, (Mycetophilidae, Culicidae), aestivators (Limoniidae, Bolitophilidae), species which seek cave systems independent of sex and season (Heleomyzidae, Trichoceridae), and opportunists (Chironomidae, Phoridae?, Dixidae?). Species belonging to other families are most likely accidental trogloxenes.

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.

The majority of the material was collected in Fennoscandia, mainly in Sweden, in the first half of the 19th century. Altogether 37 species of the tribe Exechiini could be safely identified. Three additional species are strongly indicated to be present in the collections, but could not be identified with certainty, viz. Allodia (Brachycampta) alternans (Zetterstedt, 1838), Cordyla murina Winnertz, 1863 and Stigmatomeria crassicornis (Stannius, 1831). Some of Zetterstedt's types have been erroneously synonymized and misinterpreted in modern literature. Hence, illustrations of terminalia are presented for all recognizable Exechiini types described by Zetterstedt. In order to preserve nomenclatural stability a lectotype is selected for Brevicornu griseolum (Zetterstedt, 1852) sensu auctore nec Edwards, and a neotype is selected for Allodia (Brachycampta) alternans (Zetterstedt, 1838). Two species names are reinstated, viz. Brevicornu canescens (Zetterstedt, 1852) sp. restit. stat. n. and Notolopha brachycera (Zetterstedt, 1838) sp. restit. stat. n. Two new synonyms are established, viz. Notolopha brachycera (Zetterstedt, 1838) = Allodiopsis (Notolopha) tuomikoskii Zaitzev & Maximova, 2000 syn. n., and Brevicornu griseolum (Zetterstedt,1852) = Brevicornu boreale (Lundstrom, 1914) syn. n. All type specimens of Brevicornu fusculum (Zetterstedt, 1838) have lost their abdomens. No material of Exechia parvula (Zetterstedt, 1852) or Cordyla canescens Zetterstedt, 1852 could be located in the collections. Although the type material of Exechia parvula probably is lost, the name is still valid as a junior synonym for Mycetophila nana Staeger, 1840 since Mycetophila nana Staeger, 1840 is a junior primary homonym of Mycetophila nana Macquart, 1826. Cordyla canescens has been made a junior synonym for Stigmatomeria crassicornis (Stannius, 1831). The identity of Brevicornu fusculum is highly uncertain and the name must remain as a nomen dubium. Eleven species are reinstated or correctly reported from Sweden for the first time: Allodia (Allodia) tuomikoskii Hackman, 1971, Allodia (Allodia) zaitzevi Kurina, 1998, Allodiopsis rustica (Edwards, 1941), Brevicornu canescens (Zetterstedt, 1852), Brevicornu nigrofuscum (Lundstrom, 1909), Exechiopsis (Xenexechia) crucigera (Lundstrom, 1909), Pseudexechia aurivernica Chandler, 1978, Notolopha brachycera (Zetterstedt, 1852) Synplasta gracilis (Winnertz, 1863), Tarnania dziedzickii (Edwards, 1941), and Tarnania nemoralis (Edwards, 1941).
