Aksenova et al. (2016) presented a detailed description of morphology of this snail, accompanied by a molecular analysis of its phylogenetic and taxonomic affinities. Conchologically and anatomically, K. kamtschatica is very similar to other members of the genera Ampullaceana and Peregriana and it is virtually impossible to propose a differential diagnosis for this genus. K. kamtschatica is widely distributed throughout north-eastern Asia, including Kamchatka and Chukotka peninsulas, Transbaikalia and the Amur River basin ( Kruglov and Starobogatov 1993b; Aksenova et al. 2016). Possibly, this snail is endemic to Asiatic Russia, though we cannot exclude that it also inhabits Alaska. In Kamchatka, it forms stable populations in the geothermal sites (e.g. the Valley of Geysers) and may live in warm water up to +39.9 °C ( Aksenova et al. 2016).
