Abstract A detailed morphological description of the copepod Acanthodiaptomus tibetanus and its geographic distribution on the territory of Irkutsk Region, Buryat Republic, Zabaikalsky Region and Republic of Sakha (Yakutia) within the limits of Baikal Rift Zone is presented for the first time. The authors provided information on the paleogeographic conditions of the territory these crustaceans inhabited and characterized their habitats in brief. An overview of the personal data and available literature on the geographic distribution of A. tibetanus is given. One of the major results obtained under this study was elucidation of the distribution patterns of A. tibetanus. In order to understand current distribution patterns of organisms, A. tibetanus in particular, in different basins, we carried out a historical analysis of the relief formation taking into account climatic aspects involved in these transformations.
