The frit flies (Chloropidae, Diptera) of Fennoscandia and Denmark 43/1

This volume deals with North European species of the family Chloropidae, known as frit flies or chloropid flies, a large family of acalyptrate flies including some notarial, economically pests of cereals and fodder grasses. The taxonomy, biology and faunistics of all NW European species are revised. Keys are given to subfamilies, genera and species for the adults, for the larvae to generic level as far as possible, and to specific level for a few genera. Brief descriptions of the adult flies are given for all genera and species. Species distributions in Fennoscandia and Denmark (DK) and elsewhere are briefly outlined and further tabulated in a catalogue. The known biology and ecology is summarized in general chapters and for each species. Illustrations are given of the male genitalia and also of other characters of diagnostic importance. From Fennoscandia and Denmark are known 48 genera and 209 species of frit flies: Rhodesiellinae 1 species, Oscinellinae 111 species, Chloropinae 97 species. Among them 119 species are known from Denmark, 97 from Norway, 189 from Sweden, 144 from Finland, and 115 from included provinces of Russia (Karelian Isthmus, Karelia, and the Kola Peninsula). One new genus and 11 new species are described, and some new synonyms and nomenclatural changes are proposed. Some other new species, new synonyms, and overlooked specific names resulting from this revision have been published earlier (Nartshuk 1992, 1998, 1999, 2002a; Nartshuk & Andersson 2002; Nartshuk & Przhiboro 2009; Nartshuk & Tschirnhaus 2012).

Nartshuk, Zoological Institute Academy of Sciences, St Petersburg, Russia, andamp; Dr Hugo Andersson (deceased in 2008), Zoological Institute, Lund University, Sweden. The book covers the North European fauna of frit flies that totals 209 species in 48 genera including 11 species and 1 genus described as new to science. Several species are economically important as notorial pests of cereals and fodder grasses. This is the first comprehensive treatment ever of the entire North European fauna of frit flies. It primarily facilitates species identification, but further summarizes existing knowledge about nomenclature, biology, faunistics and literature. Keys are given to subfamilies, genera and species for the adults and for the known larvae to genus or even species level. The text is supplemented with numerous illustrations of characters of diagnostic importance. Species distributions in the Nordic countries are detailed in a catalogue
