ABSTRACT: In the southern part of Uzbekistan, the abundance of mountains, rivers and vegetation cover, as well as the heat of the climate allowed the widespread distribution of terrestrial mollusсs. Research on molluscs was carried out in this area, that is, in the Boysuntau Ridge in the south of Uzbekistan, during the years 2017–2021. During the study of the collected materials, it was discovered for the first time that a terrestrial snail species, Hesseola bactriana (Hutton, 1849), for the fauna of Uzbekistan. The conchological variability of H. bactriana found in Uzbekistan was studied. The results showed that high variability was noted in shell color, the peripheral band and the palata lip. In our opinion, Uzbekistan population of this species may have originated through natural dispersal from the territory of Afghanistan.
KEY WORDS: Hesseola bactriana, shell, variability, reproductive anatomy, Uzbekistan.
