New records of Dolichopodidae (Diptera) from Khanty-Mansi Autonomous Region of Russia

New material of Dolichopodidae has been recently collected and identified, with 41 species (25 species new for the Khanty-Mansi Autonomous Region, seven species found for the first time in West Siberia, and two species new for Siberia). Campsicnemus alpinus and Nematoproctus longifilus are found outside Europe for the first time. New records of five species (Dolichopus lancearius, D. setiger, D. subpennatus, Rhaphium tibiale, Thrypticus atomus) fill gaps between European and East Siberian areas of these species. In total, 64 species are recorded in this region, which apparently make up 40–50% of actual Dolichopodidae fauna in the Khanty-Mansi Region. This paper provides a distribution pattern for each collected species
