Lost ( Vinarski and Kantor 2016).

This species is characterised conchologically by a relatively oblong shell, with high and narrow spire and moderately-inflated body whorl (see Fig. 7J, K ). The structure of the copulatory apparatus in A. lagotis is typical for the genus. Praeputium is relatively long, its length is about 1.5 times larger than the length of the penis sheath (see Fig. 8E ; Table 2 ). The range of A. lagotis covers, almost entirely, Europe, Siberia and some parts of Central Asia, including Tajikistan and western China ( Glöer 2002, 2019; Andreeva et al. 2010; Welter-Schultes 2012; Vinarski and Kantor 2016). The molecularly-confirmed records of this species were reported from different countries of northern, central and southern Europe, as well as from Tajikistan and Siberia ( Schniebs et al. 2015; Aksenova et al. 2018a).

Shell proportions of A. lagotis resemble those of A. intermedia ; however, A. lagotis typically has a much narrower spire than the latter species (compare Fig. 7I and 7J, K ).
