Associated species.

Remarks.

Martens (1879) synonymised Theodoxus doriae, the species reported by Issel (1863) from S Iran, with Theodoxus fluviatilis. Later on, Mansoorian (2000) described the operculum of Theodoxus doriae, which has only a rib, no peg. However, the shell illustrated by Mansoorian (1994) agrees well with Theodoxus fluviatilis. Thus we follow Martens’ (1879) synonymisation of Theodoxus doriae with Theodoxus fluviatilis. Our samples revealed onlythe presence of Theodoxus fluviatilis.

Distribution.

W- to Central-Palaearctic. Theodoxus fluviatilis has been considered by many authors to be an exclusively European species (see e.g. Zhadin 1952, Glöer 2002). But Bourguignat (1864), Brown (1994) and Van Damme (1984) mentioned it from NW Africa (Morocco, Algeria). Records of this species in Turkey (Yıldırım 1994), and in Iran, confirm its wide distribution. However, it does not occur in Siberia (Vinarski, pers. comm.).
