Bithynia (Bithynia) tentaculata (Linnaeus, 1758)

Rejected records.

Mazandaran Province ( Forcart 1935).


The Euro-Siberian species Bithynia tentaculata   (Linnaeus 1758) has often been mentioned from Iran, Turkey and Greece. However, this species could not be found in Greece ( Glöer et al. 2010) and probably does not occur in Turkey. The southern distribution border of this species lies possibly in N Bulgaria (Georgiev pers. comm.). An analysis of the specimens from NMB published by Forcart (1935) as Bithynia tentaculata   shows that these specimens represent Bithynia forcarti   sp. n. (see below). Thus, Bithynia tentaculata   most probably does not occur in Iran and has been confused with Bithynia forcarti   sp. n. or possibly with Bithynia mazandaranensis   sp. n. (see below).
