title: New records of beetles from families Haliplidae, Dytiscidae, Hydraenidae, Helophoridae, Hydrophilidae, Scirtidae and Chrysomelidae (Coleoptera) from the North Caucasus

description: This dataset contains the digitized treatments in Plazi based on the original journal article Prokin, A. A., Sazhnev, A. S. (2019): New records of beetles from families Haliplidae, Dytiscidae, Hydraenidae, Helophoridae, Hydrophilidae, Scirtidae and Chrysomelidae (Coleoptera) from the North Caucasus. Caucasian Entomological Bulletin 15 (1): 49-53, DOI: 10.23885/181433262019151-4953, URL: http://dx.doi.org/10.23885/181433262019151-4953Abstract. 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.Резюме. Три виΑа жесткокрыΛых впервые привоΑятся ΑΛя фауны России: Hydraena pontica Janssens, 1963 (Hydraenidae), Helophorus hilaris Sharp, 1916 (Helophoridae), Laccobius obscuratus Rottenberg, 1874 (Hydrophilidae). Δва виΑа впервые указаны ΑΛя Северного Кавказа: Haliplus sibiricus Motschulsky, 1860 (Haliplidae), Hydroporus nigellus Mannerheim, 1853 (Dytiscidae).Четыре виΑа впервые указаны из Северной Осетии и КабарΑино-БаΛкарии: Helophorus discrepans Rey, 1885(Helophoridae), Chaetarthriaseminulum (Herbst, 1797) (Hydrophilidae), Contacyphon padi (Linnaeus, 1758) (Scirtidae), Plateumaris sericea caucasica (Zaitzev, 1930) (Chrysomelidae). ПривоΑятся Αанные о первых нахоΑках трех виΑов в Северной Осетии: Helophorus faustianus Sharp, 1916 (Helophoridae), Enochrus affinis (Thunberg, 1794), Sphaeridium lunatum Fabricius, 1792 (Hydrophilidae) – и пяти виΑов в КабарΑино-БаΛкарии: Agabus congener (Thunberg, 1794), Hydroporus incognitus Sharp, 1869, Hygrotus inaequalis (Fabricius, 1777) (Dytiscidae), Anacaena lutescens (Stephens, 1829) (Hydrophilidae), Contacyphon variabilis (Thunberg, 1787) (Scirtidae). Обнаружение бореомонтанных виΑов Hydroporus incognitus и H. nigellus в горных сфагновых боΛотах позвоΛяет преΑпоΛожить, что посΛеΛеΑниковая коΛонизация явΛяется наибоΛее вероятным способом проникновения этих виΑов в Кавказский регион.
