Türkiye, which is one of the important speciation regions of the Palearctic Region, is one of the distribution centers of the genus Dreissena. Since the 1800s, many taxa belonging to the genus have been mentioned, especially by European researchers. However, in recent years, the existence of three taxa has been determined mainly in the lentic systems of Dreissena caputlacus (SCHÜTT 1993), Aegean and Mediterranean, Southeastern Anatolia; D. polymorpha anatolica (LOCARD 1893) especially in the Lakes Region and Aegean Sea. It has been reported that D. polymorpha gallandi (LOCARD 1893) is distributed in the Marmara and Western Black Sea Regions.
In this study, the distribution of the genus has been tried to be revealed partially with Dreissena specimens collected from at least certain regions in line with the latest findings. However, it cannot be said that Dreissena taxa have not been fully revealed yet.
