Nineteen species of gall midges (Diptera: Cecidomyiidae) new to Denmark

We report the first records to Denmark of nineteen gall midge species: Anabremia bellevoyei, Bayeriola thymicola, Contarinia asclepiadis, Dasineura virgaeaureae, Lestodiplosis achilleae, Lestodiplosis chrysanthemi, Lestodiplosis cirsii, Lestodiplosis coni, Macrolabis achilleae, Ozirhincus millefolii, Rhopalomyia baccarum, Tricholaba viciarum, Trotteria ligustri, Zeuxidiplosis giardi and three species of Contarinia only determined to the genus level. With the reported records, the Danish gall midge fauna comprises 302 named species and 24 species identified to the genus level only. Of these, 87 have been found during the last decade, the largest number of new species to Denmark ever reported for a ten year period. However, the fact the few individuals have made these findings at a limited number of sites strongly suggest that the Danish gall midge fauna still is very incompletely known
