ABSTRACT. Twenty-seven species of six families are recorded from the Sikhote-Alin Nature Reserve: Gyrinidae (1 species), Haliplidae (2), Noteridae (1), Dytiscidae (13), Hydrophilidae (9), and Hydraenidae (1). Additional records are provided for 29 species from Primorsky Krai: Dytiscidae (8), Hydrophilidae (20), and Elmidae (1). Three species (Oreodytes mongolicus, Sphaeridium bipustulatum, and S. marginatum) are recorded for the first time from the Russian Far East. One species of Gyrinidae (Gyrinus sachalinensis), one species of Dytiscidae (Oreodytes mongolicus), and two species of Hydrophilidae (Sphaeridium bipustulatum and S. marginatum) are recorded from Primorsky Krai for the first time. A new synonymy is established: Cercyon terminatus (Marsham, 1802) = Cercyon  emarginatus Baranowski, 1985 syn.n.

KEY WORDS: Russian Far East, Sikhote-Alin Nature Reserve, new records, protected areas.
