Essay

The biodiversity of the group in studied region is established. One additional species entirety within the Ponto-Caspian zoogeographical complex was discovered. It is treated as a separate zoogeographical group of species which most likely is directly connected in their origin with the ancient fauna inhabited of Pontian or even Maeotian basin. The hypothesis of the autochthonous origin of European species Potamopyrgus is forwarded. The systematic position of ten genera has been revised. An original interpretation of homeomorphy is suggested. The negative role of homeomorphy for the systematics and phylogeny is shown. A new concept on periodicity in the development of the Neogene malacofauna in the Eastern Paratethys has been proposed.
