New ostracod species of the Nirihuau Formation (Oligocene) from its type area (near San Carlos de Bariloche) Rio Negro Province, Argentina

Five new limnic taxa of Ostracoda are described and illustrated: Chlanydotheca? nirihuauensis sp. nov., Eucypris? barilochensis sp. nov., Candona? mapuche sp. nov., Eucandona? patagonica sp. nov. and Limnocythere? nahuelhuapiana sp. nov. They are from the Nirihuau Formation of Oligocene age. The sal...
