Discussion.

The name Planorbis dubius was first used by Hartmann (1821, p. 254) for an extant species from Zurich region in Switzerland. The name is not available from this publication, since Hartmann did not give a description or indication (see also AnimalBase project 2005-2014). He first described and thus formally introduced it in Hartmann (1844, p. 111). Today its status is disputed. Glöer (2002, p. 253) ranked it as forma within Planorbis carinatus Müller, 1774. Later, Glöer and Pešić (2010) stated that Hartmann's material contained two different taxa, i.e. Planorbis planorbis and Planorbis carinatus, making Planorbis dubius a junior synonym of both. Finally, Kantor et al. (2010) listed it as accepted species in their catalogue of Russian continental mollusks. In summary, although the status of the extant species is doubtful, the name is available. This makes Planorbis dubius Gorjanović-Kramberger, 1890 a primary homonym of Planorbis dubius Hartmann, 1844. Here follow Wenz (1923c) and classify the replacement name within Gyraulus .
