要約

The paper deals with problems of morphology, diversity and taxonomy of the genus Deflandr/ea Eis., whose composition has been revised several times. In different years the species included into the genera Alterbidinium, Arvalidinium, Chatangiella, Isabelidinium, Ceradinium and other as have been excluded from it. The basic diagnostic criteria are presented for the genus Deflandrea s. str., and its species and infraspecific taxa (subspecies and varieties). Biozones and acme zones of species are established, and their geographic and stratigraphic distribution is traced in the Palaeogene of the southern territories of the former USSR, from the Carpathians to the Eastern Caspian area. Two new infraspecific taxa are described.
