Remarks.

The species Planorbis planorbis and Planorbis intermixtus can only be distinguished by the number of prostate diverticula ( Glöer and Pešić 2010). All Planorbis spp. collected in Iran have been anatomically studied and no Planorbis planorbis could be found. Thus we list the old records from Iran under Planorbis intermixtus .

In addition, Planorbis subangulatus Philippi, 1844 and Planorbis persicus Ancey, 1900 have been mentioned from Iran ( Ancey 1900, Biggs 1937). Both species have been described on the basis of the shells, the morphology of which falls within variability of Planorbis intermixtus . Thus we list these species under Planorbis intermixtus .

Distribution.

Turkey, Iran, N India.
