During the analyses of terrestrial gastropods from loess containing Palaeolithic archaeological remains in Southern Tajikistan, a new species of valloniid, here described as Vallonia ranovi n. sp., was encountered at a site at Khonako near Khovaling. The new species occurs in interglacial stages of the upper Middle Pleistocene and also near the lower boundary of the Upper Pleistocene (transition to MIS 5e). Two shells of presumed Holocene age and a single modern shell, all collected 20 km north of Khonako, are also assigned to V. ranovi n. sp.
