Lectotype.

Naturmuseum Saint-Gallen, Switzerland (designated in Vinarski and Glöer 2007).

A. ampla is distributed in Europe (except the northernmost and southernmost latitudes), Western Siberia and the southern part of Eastern Siberia ( Glöer 2002, 2019; Vinarski and Glöer 2007; Andreeva et al. 2011; Welter-Schultes 2012). The shell of this species is relatively large, with low spire and very expanded aperture; conchologically, A. ampla can sometimes be confused with R. auricularia; however, the former species has straight or virtually absent columellar fold, which is not characteristic for R. auricularia . Shell height may reach 30-32 mm. The lengths of the praeputium and the penis sheath in this species are roughly equal (see Fig. 8A), with ICA close to 1.00. In a sample of A. ampla (n = 52), collected from several water-bodies of Russia, ICA was equal to 0.88 ± 0.13 (min - max = 0.51-1.21).
