The Free Margin Contact Structures in Some “Palaeocopid” Ostracods and their Bearing on Classification

According to the presence of a calcified inner lamella in some of the so-called “palaeocopid” ostracods new taxa are erected: Gerubiellidae n. fam. with the genus Gerubiella n. gen. (type species Buregia krestovnikovi Polenova), Netzkainidae n. fam. with the genus Netzkaina n. gen. (type species Saccelatia bimarginata (Netzkaja) and Anfedatiidae n. fam. with the genus Anfedatia n. gen. (type species Pribylites alveolutus Abushik). These ostracods cannot belong to the Palaeocopia. Their systematic position is unknown.
