Lestremiinae (wood midges) are a group of finy forest-dwelling dipterans with a world-wide distribution. The present inventory, coupled with a taxonomic revision, documents of occurrence of 230 species, 28 genera and 9 tribes of Lestremiinae in Fennoscandia and Denmark. Species-based information on distribution and phenology is…provided and the biogeographic patterns identified are discussed. Diagnoses, illustrations and keys facilitate the identification of species (adults). An illustrated key makes the identification of all the supraspecific taxa known from the Holarctic region possible. Sixty new synonyms and 12 new combinations are proposed, and 1 new genus and 56 new species are described. The adult morphology of Lestremiinae is outlined and re-examined in the context of phylogeny and classification. Evidence is supplied that the Lestremiinae are a paraphyletic assemblage. A proposal for a natural system of the Cecidomyiidae (gall midges), including Lestremiinae, is presented. The systematic position of the Cecidomyiidae in relation to the Sciaroidea is briefly discussed. The study of the taxonomy of Holarctic and Fennoscandian Lestremiinae is outlined in a historical context. The methods of studying adult wood midges are explained. 333 pp., 104 figs, hardcover gr. 8 [24.6 x 17 cm].

This revision summarizes the results of four years of taxonomic and faunistic research into the Porricondylinae of Sweden. Porricondylinae are a little-sutdied, globally distributed group of forest-dwelling Diptera, with several hundred named species in Europe and fewer than 30 species recorded in Sweden prior to this study. The… present inventory shows 206 species and 53 general of Porricondylinae to occur in Sweden, including 57 species and 10 genera new to science. Male genitalia and other adult morphological structures of taxonomic significance are illustrated for almost all species. Other indentification tools, such as keys and diagnoses, are provided for tribes, genera and species. The conceptions of supraspecific taxa are outlined in a historical context. Revision work takes account of taxa from all the Holarctic region, resulting in 81 new synonyms and 49 new combinations. Based on actual specimens adult morphology of Porricondylinae is reexamined and characters observed are analyzed in terms of phylogeny. A new classification is proposed that eliminates the traditional, paraphyletic Porricondylinae, instead favoring two large subdivisions, Winnertziinae and Porricondylinae sensu stricto. 392 pp., 181 figs, hardcover gr. 8 [24.6 x 17 cm].
