ABSTRACT. The microcrustacean fauna (Cladocera, Copepoda and Ostracoda) of continental water bodies in the southern portion of Russian Far East is studied inadequately relative to the European Part of the country. The aim of the present study is to make inventory of the Cladocera and Copepoda fauna of the Lake Bolon basin and evaluate the biogeographic status of microcrustaceans found there. In toto, 45 taxa of Cladocera (of which four taxa could be identified only to genus) and 13 taxa of Copepoda are found. For some taxa we provide short morphological descriptions and comments on their distribution ranges in Northern Eurasia. We subdivided all taxa into five main faunistic complexes. In general, fauna of Cladocera and Copepoda of the Lake Bolon Basin is diverse and specific, it includes endemics of the Far East. In the investigated region cladocerans are more speciose and heterogeneous in their range types relative to the copepods. But most part of revealed cladoceran and copepod taxa belong to an artificial “complex” of species which are widely distributed in Eurasia (or even in Holarctic), or regarded as “cosmopolitan”. Each such taxon apparently needs an accurate taxonomic revision in the global scale keeping in mind Frey’s non-cosmopolitanism paradigm. Only newly obtained adequate data could provide a basis for biogeographical analysis of the Cladocera and Copepoda of the Far East fauna as a whole.

KEY WORDS: Crustacea, Cladocera, Copepoda, morphology, taxonomy, fauna, biodiversity.
