Abstract
Ostracods from the Middle Ordovician Nalednyi Formation of the Udokan Region are investigated in detail. A brief history of the study of these deposits and description of the new species Egorovellina (?) shuvalovae sp. nov., Cherskiella baikalica sp. nov., Gontiella mira gen. et sp. nov., Leperditella nalednaya sp. nov., Hallatina opima sp. nov., Primitia kalarensis sp. nov., Glandites planus sp. nov., and Bollia sinitsae sp. nov. are provided. The previously known ostracod species described in open nomenclature are figured.
