MATERIAL EXAMINED. 1: 21.IV.2015, 4 exs. (D.E.Shcherbakov); 2: 21.IV.2015, 8 exs. (D.E. Shcherbakov); 5: 14– 23.04.2015,

21 exs. (D.E. Shcherbakov); 10: 24–27.IV.2015, 8 exs. (D.E. Shcherbakov).

DISTRIBUTION. Europe, Central Asia, Mongolia, West and East Siberia, China, South Korea, Russian Far East (Kuril Islands, Primorsky Krai), Japan [ Jäch, 1988, 2015; Shatrovskiy, 1989 a, Gusakov, 2009; Palatov, 2014].

The studied material from the Sikhote-Alin Nature Reserve is represented by 27 species of six families: Gyrinidae (1 species), Haliplidae (2), Noteridae (1), Dytiscidae (13), Hydrophilidae (9), and Hydraenidae (1).

Taking into account published data, the fauna of the studied families of the Sikhote-Alin Nature Reserve includes only 28 recorded species, which indicates an insufficient level of regional faunal investigation. For example, more than 80 species of beetles of the studied families are recorded from the Lazovsky Nature Reserve [ Gusakov, 2009; Nilsson, Sundukov, 2009a, b, c; Prokin, 2009, 2010].

Additional records from Primorsky Krai Additional material was collected by different persons in 2015–2020 from various protected areas and their buffer zones in Primorsky Krai ( Fig. 14 ). Distributional data for species that were indicated in the list above are not provided again.
