Abstract. Three species of beetles are recorded for Russia for the first time: Hydraena pontica Janssens, 1963 (Hydraenidae), Helophorus hilaris Sharp, 1916 (Helophoridae), Laccobius obscuratus Rottenberg, 1874 (Hydrophilidae). Two species are recorded for the first time for the North Caucasus: Haliplus sibiricus Motschulsky, 1860 (Haliplidae), Hydroporus nigellus Mannerheim, 1853 (Dytiscidae). Four species are recorded for the first time for North Ossetia and Kabardino-Balkaria: Helophorus discrepans Rey, 1885 (Helophoridae), Chaetarthria seminulum (Herbst, 1797) (Hydrophilidae), Contacyphon padi (Linnaeus, 1758) (Scirtidae), Plateumaris sericea caucasica (Zaitzev, 1930) (Chrysomelidae). Distributional data about three new species for North Ossetia are given: Helophorus faustianus Sharp, 1916 (Helophoridae), Enochrus affinis (Thunberg, 1794), Sphaeridium lunatum Fabricius, 1792 (Hydrophilidae); and five species for Kabardino-Balkaria: Agabus congener (Thunberg, 1794), Hydroporus incognitus Sharp, 1869, Hygrotus inaequalis (Fabricius, 1777) (Dytiscidae), Anacaena lutescens (Stephens, 1829) (Hydrophilidae), Contacyphon variabilis (Thunberg, 1787) (Scirtidae). General distribution of Hydroporus incognitus and H. nigellus and their association with mountain peat bog habitats in the North Caucasus, which considered herein as postglacial relict ecosystems, allows to assume that the postglacial colonization is the most likely way for these species into the Caucasus region.

Обнаружение бореомонтанных видов Hydroporus incognitus и H. nigellus в горных сфагновых болотах позволяет предположить, что послеледниковая колонизация является наиболее вероятным способом проникновения этих видов в Кавказский регион.

Introduction

The level of knowledge on water and amphibiotic (with water-living larvae) beetles from families Haliplidae, Dytiscidae, Hydraenidae, Helophoridae, Hydrophilidae, Scirtidae and Chrysomelidae (Coleoptera) of the North Caucasus is still poorly known, though several studies have already been published [Zaitzev, 1927; Belyashevsky, 1991; Maksimenkov, 1995; Brehov, 2007; Shapovalov et

al., 2012; Prokin et al., 2008, 2016, 2017 etc.]. Catalogues providing information about the occurrence of the species in the Caucasian countries were published by Vondel [2017] (Haliplidae), Hájek [2017] (Dytiscidae), Jäch [2015] (Hydraenidae), Fikáček et al., [2015a, b] (Helophoridae, Hydrophilidae), Klausnitzer [2016] (Scirtidae) and


Silfverberg [2010] (Chrysomelidae: Donaciinae). Beetles of studied families of three administrative regions of Russia in the North Caucasus have been more thoroughly reviewed in the last 10 years: Adygea [Medvedev et al., 2010; Nikitsky, Shapovalov, 2010; Prokin, Shapovalov, 2010; Shapovalov, 2010a, b], Dagestan [Brekhov et al., 2013; Brekhov, Ilyna, 2016] and North Ossetia [Shapovalov et al., 2018]. In our recent paper data on some water beetles assemblages of eight mountane peatlands of the North Caucasus is published [Prokin et al., 2019]. That article includes some species, recorded here, but without labels data and distributional notes.

The aim of this paper is to report new records of the water beetle fauna of the North Caucasus.

Discussion

Our data show insufficient knowledge of the water and amphibiotic beetle fauna of the region as a whole and, in particular, of such ecosystems as mountain peat bogs and water-falls. Only one species, collected in water- fall in Cherek canyon is a new for the fauna of Russia representative of the family Hydrophilidae. In the past this species was considered as a subspecies Laccobius obscuratus obscuratus Rottenberg, 1874 [Fikáček et al., 2015b], but recently was restored as a separate species, as well as

L. aegeus Gentili, 1974 and L. meridionalis Gentili, 1974 [Gentili, Shaverdo, 2016]. Majority of species, collected in Sphagnum peat bogs in North Ossetia and Kabardino- Balkaria represents new faunal records of various levels, which underline the insufficient knowledge about these rare ecosystems in the North Caucasus. The findings of two boreal-mountain species Hydroporus incognitus and

H. nigellus (Dytiscidae) in a mountain Sphagnum peat bogs are particularly interesting. The first one was recorded once from a forest pool in 1500 m in Karachay-Cherkessia [Belyashevsky, 1991], and the second one never been recorded from the North Caucasus. General distribution of species and their association with mountain peat bog habitats in the North Caucasus, which considered herein as postglacial relict ecosystems, allows to assume that the postglacial colonization is the most likely way for these species into the Caucasus region.
