KEY WORDS: Coleoptera, Helophoridae, Hydrochidae, Hydrophilidae, distribution, new record, Russia. КЛЮЧЕВЫЕ СЛОВА: Coleoptera, Helophoridae, Hydrochidae, Hydrophilidae, распространение, новые находки, Россия. ABSTRACT. New data on the distribution of Helophoridae, Hydrochidae, and Hydrophilidae (Coleoptera: Hydrophiloidea) species in Russia and adjacent lands are reported. New localities contributing to the knowledge of the ranges of nine species of Helophoridae, two species of Hydrochidae, and 20 species of Hydrophilidae are given. Two species are new to Russia, two to Asia, one to Armenia, one to Uzbekistan, nine to West Siberia, 11 to the Urals, 13 to the Altai, two to the Caucasus, one to Buryat Republic, five to Yamal Peninsula, and one to Vaygach Island. РЕЗЮМЕ. В статье содержатся новые данные о распространении видов семейств Helophoridae, Hydrochidae и Hydrophilidae (Coleoptera: Hydrophiloidea) в России и сопредельных странах. Приводятся новые местонахождения девяти видов Helophoridae, двух видов Hydrochidae и 20 вида Hydrophilidae, уточняющие сведения об их ареалах. Два вида впервые указываются для России, два для Азии, один для Армении, один для Узбекистана, девять для Западной Сибири, 11 для Урала, 13 для Алтая, два для Кавказа, один для Бурятии, пять для Ямала, один для острова Вайгач. Recent compilations of new data on the distribution of Hydrophiloidea in Russia and adjacent lands were published by Ryndevich [2001, 2003, 2007], Hebauer and Ryndevich [2005], Prokin [2006, 2008] and Prokin with coauthors [2002]. Results of studying private collections and collections of several museums were used as the material for this work. New localities for nine species of Helophoridae, two species of Hydrochidae, and 21 species of Hydrophilidae are recorded here. Two species new to Russia, two to Asia, one to Armenia, one to Uzbekistan, nine to West Siberia, 12 to the Urals, 13 to the Altai, two to the Caucasus, one to Buryat Republic, five to Yamal Peninsula, and one to Vaygach Island are reported.

Material and methods
Names of depositories of the material examined are abbreviated as follows: ZISP Zoological Institute of Russian Academy of Sciences (St. Peterburg); ZMUM Zoological Museum of Moscow State University (Moscow); cAK private collection of A.G. Koval (St.-Petersburg); cAP private collection of A.A. Prokin, (Voronezh); cPP private collection of P.N. Petrov (Moscow); cSR private collection of S.K. Ryndevich (Baranovichi); cTA private collection of T.R. Andrejeva (Moscow).

Introduction
The distribution of Hydrophiloidea in the Palaearctic region was reviewed by M. Hansen [2004]. Kirejtshuk and Shatrovskiy [2001a, 2001b, 2001c] summarized the available data on the fauna of Hydrophiloidea of the former USSR.

Results and discussion
New data are listed below. All the labels are translated from Russian, except indicated otherwise. Comments and

ACKNOWLEDGEMENTS. We are grateful to Dr. G.S. Medvedev (Zoological Institute of Russian Academy of Sciences, St.-Petersburg), Dr. N.B. Nikitskiy (Zoological Museum of Moscow State University), Dr. A.G. Koval (St.-Petersburg) for the chance to borrow their materials for study. Specimens from the South Urals and Teletskoye Lake in the Altai were collected in the course of expeditions organized by F.N. Petrov (Arkaim Reserve, Chelyabinsk Oblast) and D.Y. Tishechkin (Department of Entomology, Moscow State University), respectively. The success of Yamal Peninsula beetle-collecting expeditions is largely due to the help of V.G. Shtro (Ecological Station of Institute of Plant and Animal Ecology, Labytnangi), his employees, and guest researches at the station, as well as many local residents who provided our expeditions with transport and assisted us in many other ways. We also thank all the persons who (beside ourselves) collected the specimens we examined. Work of A. Prokin is executed at financial support of the RFFI (the grant 08-0499024-р_офи).
