ABSTRACT. Data on the biodiversity of aquatic insect fauna of the orders Ephemeroptera, Plecoptera and Trichoptera, inhabiting lotic and lentic environments in the southern spurs of the Chersky Range (Magadanskaya Oblast and the Republic of Sakha, Yakutia), are provided for the first time. The species richness of these groups is modest, despite the biotopes’ considerable diversity. Some reasons explaining the sparse fauna of the study area are discussed.
KEY WORDS: Aquatic insects, fauna, biodiversity, Northeast Asia, Chersky Range, glaciations, climate, biotopes, Magadanskaya Oblast, Republic of Sakha (Yakutia).
