ABSTRACT. New faunistic data are presented for six families of water beetles from the Palearctic region. Two species are recorded for the first time from Armenia and the Caucasus: Coelostoma transcaspicum Reitter, 1906 and Enochrus salomonis (J. Sahlberg, 1900). Six species are recorded for the first time from Kyrgyzstan: Haliplus furcatus Seidlitz, 1887, Hydaticus ponticus Sharp, 1882, Oreodytes mongolicus (Brinck, 1943), Enochrus coarctatus (Gredler, 1863), Laccobius quaesitus Gentili, 1988 and Dryops renateae Greń et Przewoźny, 2016. Other countries records are: Enochrus coarctatus, Laccobius hindukuschi Chiesa, 1966, Laccobius quaesitus and Dryops renateae (Kazakhstan), Dryops similaris Bollow, 1936 (Tajikistan). First provincial records are listed for Hydroporus marginatus (Duftschmid, 1805) (Turkestan Region of Kazakhstan), Helophorus mongoliensis Angus, 1970 (Xinjiang Uygur Autonomous Region of China), Hydrochus megaphallus Berge Henegouwen, 1988 (Mykolaiv Oblast of the Ukraine), Spercheus emarginatus (Schaller, 1783) (Jalal-Abad Region of Kyrgyzstan), Berosus fischeri Schödl, 1993 (Xinjiang Uygur Autonomous Region of China) and Laccobius obscuratus Rottenberg, 1874 (Krasnodar Krai, Russia). Rare and little-known species confirmed from Kazakhstan (Deronectes vestitus (Gebler, 1848), Hydroporus crinitisternus Shaverdo et Fery, 2001, Helophorus salinus Angus et Litovkin, 2018, Coelostoma transcaspicum) and Kyrgyzstan (Agabus turcmenus Guignot, 1957) from the new localities with the data of their habitat preferences. The coordinates of the type locality and deposition of the type material are clarified for Helophorus salinus. Most species records are illustrated with original photographs of the habitus and male genitalia.
