The fauna of stoneflies (Insecta, Plecoptera) of the Putorana Plateau in the north of East Siberia, Russia, has been investigated for the first time.The study is based on the collections of adult and immature stoneflies made by the second author in late June to mid-August 2019, 2021, 2022, and 2024 in 9 areas in the western and central parts of Putorana, using 12 sampling techniques.According to these results, the stonefly fauna of Putorana is poor; in total, only 12 species from 9 genera in 5 families were recorded.Among them, there are 5 species of Capniidae, 3 spp. of Chloroperlidae, 2 spp. of Nemouridae, and one species of each Leuctridae and Perlodidae.Seven species are reported for the north of Eastern Siberia for the first time.The species distribution by the altitudinal landscape zones and habitats is discussed.In Putorana, stoneflies inhabit all types of running and standing waters, occurring in all altitudinal zones, from the boreal forest to the mountain desert.According to the chorological analysis, the species with the East Palaearctic distribution are numerous (7), whereas species with the Transpalaearctic, Amphipacific, Holarctic Circumpolar, and Arctic European-Asian range types are single..
