title: [Landscape and zonal distribution of bloodsucking mosquitoes and horse flies (Diptera: Culicidae, Tabanidae) in the northeastern Russian Plain].
abstract: The data on the distribution of 34 species of bloodsucking mosquitoes and on 42 horsefly species of the fauna of the northeastern Russian Plain are given. The analysis of the landscape and zonal changes in species diversity and their abundance was performed. Species diversity of these families increased northwards. Two borders of the fauna's depletion were discovered: at the border between the middle and northern taiga subzones (mosquitoes and horseflies) and at the border between the northernmost taiga subzone and the forest-tundra zone (horseflies only). The northern and southern boundaries of species ranges in the region are identified.
