Abstract: The first data on the population genetic structure of the D. cristata Sars, 1862 and D. longiremis Sars, 1862 species (Anomopoda: Daphniidae) from the water bodies of North Eurasia are present. The variability of the 12S gene fragment of the mtDNA for these taxa belonging to subgenus Daphnia (Daphnia) O.F. Müller, 1776 (Crustacea: Cladocera) in this region is studied, and the phylogenetic analysis performed. The genealogical relationships between haplotypes of the D. cristata and D. longiremis species and their geographical distribution are shown. Our new data allow us to suggest a recent rapid spatial expansion for D. cristata during the Late Pleistocene and Early-Middle Holocene periods. According to the results of the study, the distribution zones of D. cristata and D. longiremis species are separated in the latitudinal direction with the zone of their contact in Central Yakutia. Our results provide convincing evidence for the influence of ice ages and interglacial on the formation of modern genetic diversity and the phylogeographic structure of D. cristata and D. longiremis.
