TL.

Switzerland ( Studer 1820).

Lectotype.

Naturhistorisches Museum der Burgergemeinde Bern, Switzerland (see Forcart 1957).

Shell ovate-conical, with prominent, but relatively-low spire and moderately-inflated body whorl. Praeputium and penis sheath light-coloured, their lengths are almost equal, though the praeputium is typically slightly longer (see Fig. 8D ). The mean values of ICA slightly exceed 1.0 ( Kruglov 2005; see also Table 2 ). According to genetic data, A. fontinalis is distributed in Europe, from Switzerland eastward to south of the European Russia, as well as in Turkey ( Aksenova et al. 2018a). The previous recordings of this species from the Urals and Siberia ( Kruglov and Starobogatov 1993b; Khokhutkin et al. 2009; Andreeva et al. 2010) require molecular confirmation.

Taxonomic remark.

This European species of radicine snails was not listed as valid by most authors ( Hubendick 1951; Glöer 2002; Welter-Schultes 2012), except by the Russian malacologists ( Kruglov and Starobogatov 1983b, 1993b; Khokhutkin et al. 2009; Andreeva et al. 2010). Aksenova et al. (2018a) have shown that specimens identified as Lymnaea (Peregriana) fontinalis sensu Kruglov & Starobogatov, 1993 form a species-rank clade, sister to A. lagotis . Shells of A. fontinalis sensu Kruglov and Starobogatov (1993b), studied by us, were similar to the lectotype shell illustrated by Forcart (1957) [see Fig. 7G, H ]. The presence of A. fontinalis in Switzerland (where its type locality lies) has been confirmed molecularly (Aksenova et al. 2018). This species is morphologically similar to A. lagotis , but may be distinguished by a lower spire and more inflated body whorl.
