Mykofaga gallmyggor (Diptera: Cecidomyiidae exkl. Cecidomyiinae) i Sverige: statusrapport efter 15 års taxonomisk inventering, kommentarer till artlistan och beskrivning av Camptomyia alstromi sp. nov.

Abstract

As a result of 15 years of taxonomic inventory, the Swedish fauna of mycophagous gall midges (Diptera: Cecidomyiidae excl. Cecidomyiinae) is shown to include 97 genera (incl. 2 subgenera) and 639 species (incl. 19 aggregate species), not counting 178 species identified as unnamed. Species are listed and annotated regarding their geographical distribution outside and within Sweden, their first mention for Sweden in literature (“first report”), and publications useful for identification. Camptomyia alstromi Jaschhof & Jaschhof is described as a new species. Paurodyla serrulata (Jaschhof, 2013), previously classified in the genus Porricondyla Rondani, 1840, is a new combination. Species reported for the first time as occurring in Sweden are: Anarete corni (Felt, 1907); Anarete johnsoni (Felt, 1908); Anarete triarthra Edwards, 1938; Campylomyza cornuta Jaschhof, 1998; Campylomyza nigroliminata Mamaev, 1998; and Parepidosis ulmicorticis Mamaev, 1964. The last two species are diagnosed and illustrated. Provided also are: an introduction to the target group regarding diversity, biology, geographical distribution and study methods; an overview of classification; an outline of the inventory’s history; and a discussion reflecting on the status quo and the prospects for mycophagous cecidomyiid taxonomy. As a further component of the discussion, an attempt is made to estimate the number of species of Cecidomyiidae both in Sweden and the World, based on data at the authors’ disposal including that presented here.
