Discussion.

The species name established by Sandberger is a primary homonym of Planorbis micromphalus Fuchs, 1870, although he was apparently aware of the existence of this name (compare Sandberger 1875, p. 700). Also Lőrenthey (1902, p. 190) knew about the identical naming and discussed the differences between both taxa, but did not take appropriate steps to clarify this problem. Fuchs' species was first described from the Pannonian of Rădmănești in Romania and has been recombined with Gyraulus by Wenz (1923c, p. 1562; see also Harzhauser et al. 2002, p. 106).
