RESULTS OF THE STUDY OF BEETLES OF THE FAMILY HETEROCERIDAE (COLEOPTERA) IN RUSSIA AND NEIGHBORING TERRITORIES (2015–2019)

In 2015 year, for the first time in Russia, systematic investigations into poorly studied group of Coleoptera family Heteroceridae were initiated. Initial results (for past 5 years) are presented this work. Data obtained from these studies can be divided several thematic groups: acts, faunistic findings (including zoogeographic notes), and materials on bioecological features heterocerida. Systematics: based examination type specimens Hetero?erus kamtschaticus Egorov, 1989, its synonymy is with Heteroerus fenestratus (Thunberg, 1784) established. The validity Heterocerus fausti Reitter, 1879, H. heydeni Kuwert, 1890 restored. Faunistics: Augyles interspidulus (Charpentier, 1979), A. tokejii Nomura, 1958, turanicus (Reitter, 1887), marmota (Kiesenwetter, 1850), kaszabi Charpentier, 1979 recorded Russia; lists new heterocerids species European part Caucasus, Ural, West Siberia, Russian Far East, Azerbaijan, Kyrgyzstan, Tadjikistan, Uzbekistan, Mongolia presented. Ecology: time, composition structure heterocerid population littoral zone waterbodies north Lower Volga region; data biotopical diversification, seasonal dynamics hibernation some mud-loving beetles position food webs riparian communities Russia discussed, main trophic links within related recorded. Symbionts also discussed.
