FAUNA AND DISTRIBUTION OF THE PODONOMINAE, DIAMESINAE, PRODIAMESINAE, ORTHOCLADIINAE AND CHIRONOMINAE (DIPTERA, CHIRONOMIDAE) OF THE RUSSIAN FAR EAST AND BORDERING TERRITORY

Abstract

An updated chironomid list of 5 subfamilies and their distribution in the Russian Far East and Sakha (Yakutia) are given and discussed. Nine hundred thirty one species in 141 genera are recorded: Podonominae – 8 species (4 genera), Diamesinae – 60 species (13 genera), Prodiamesinae – 11 species (4 genera), Orthocladiinae – 496 speecies (68 genera) and Chironominae – 238 species (53 genera). During the period of investigation 5 genera, 1 subgenus and 223 species in 68 genera have been described as new to science. The highest number of species (555) was found in the Amur River basin, the lowest (51) in Wrangel Island. Most recorded species (68 %) are Palaearctic in distribution, 32 % are Holarctic.
