Peyerimhoffia vagabunda – new sciarid species (Sciaridae, Diptera) for the entomofauna of Ukraine

Summary/Abstract: Peyerimhoffia vagabunda (Winnertz, 1867) is a widespread sciarid species (Diptera, Sciariadae) which occurs in 20 European countries and Asia (recorded in Kazakhstan, Altai, Primorsky Krai and China). Previously, P. vagabunda as well as the other species from the genus Peyerimhoffia Kieffer, 1903 was unknown to the Ukrainian entomofauna. In the framework of taxonomic and ecological research on Sciaridae in Ukraine some chorological and faunistic peculiarities of P. vagabunda have been studied. We collected material during expeditions and excursions in different biotopes of Ukraine from 2013 to 2018 by the method of non-count sweeping with an entomological net. Collected imagoes were placed into 5 ml vials with 76% ethanol. In the laboratory, the fixed material was dehydrated in absolute ethanol and mounted on slides in Euparal. We have found five new localities of P. vagabunda in three regions – Kyiv (one locality in the National Natural Park “Holosiivskyi”), Volyn (four localities in the National Natural Park “Tsumanska Puscha”) and Odesa (one locality in the National Natural Park “Tuzlovski Lymany”). All findings were registered in four biotope types: G1.A16 Sub-continental hornbeam-oak forests, E5.22 Mesophile fringes – post forest-felling mixed-species grassland, G1.95 Birch fresh and dry forests and G1.C3 Robinia plantations.
