ABSTRACT: We discovered subfossil remains of Phreatalona protzi (Hartwig, 1900) (Cladocera: Anomopoda: Chydoridae) in a short sediment core taken from a small tundra lake Pe-03 located in the Pechora River delta, North-East of European part of Russia. This species had been described previously only from Central and Northern Europe. The occurrence of P. protzi in the Russian Arctic suggests that this chydorid species must be much more widely distributed than previously reported, and in the near future we expect findings of this species in other regions of Russia.

KEY WORDS: Phreatalona protzi, Cladocera, Arctic, thermokarst lakes, Pechora Delta, paleolomnology.
