Abstract
In total 65 Diptera species from 20 families (Anisopodidae (2 spp.), Asilidae (1), Bibionidae (1), Clusiidae (1), Culicidae (8), Dolichopodidae (7), Drosophilidae (4), Dryomyzidae (1), Empididae (2), Heleomyzidae (5), Hybotidae (5), Lauxaniidae (4), Limoniidae (9), Opomyzidae (2), Pallopteridae (2), Psychodidae (6), Rhagionidae (2), Scatopsidae (1), Trichoceridae (1) and Ulidiidae (1)) were recorded. The species Drapetis flavipes Macquart, 1834 (Hybotidae), is recorded for the first time in Slovakia. Ten species belong among uncommon or rare (namely: Atypophthalmus (Atypophthalmus) inustus (Meigen, 1818), Calliopum splendidum Papp, 1978, Dioctria linearis (Fabricius, 1787), Cheilotrichia (Empeda) neglecta (Lackschewitz, 1927), Chrysopilus asiliformis (Preyssler, 1791), Ochlerotatus (Ochlerotatus) nigrinus (Eckstein 1918), Philosepedon (Philosepedon) austriacum Vaillant, 1974, Suillia variegata (Loew, 1862), Toxoneura modesta (Meigen, 1830) and Trichomyia urbica Curtis, 1839). On the other hand, two invasive species are also reported. Drosophila (Sophophora) suzukii (Matsumura, 1931) is an invasive crop pest and Aedes (Finlaya) japonicus japonicus (Theobald, 1901) is an invasive biting pest, a potential vector for various diseases. City parks are also important from the point of view of Diptera biodiversity and more attention needs to be paid to them.
