A rich ostracod assemblage consisting of 30 species from the Delingde Formation, Upper Ordovician of the Siberian platform, is studied for the first time. Thirteen new species of the genera Coelochilina, Retiprimites, Boreobolbina, Moierina, Leperditella, Planiglandites gen. nov., Ochesaarina, Bassleratia, Jatella, Rectella, Bairdiocypris, and Uthoernia are described and figured. For the previously described species, only images are provided. The stratigraphic distribution of ostracods in several sections of the stratotype locality on the Morkoka River is characterized.
