The new taxon was discovered during fieldwork in 2021\u20132022 in Mandaeti village, Imereti, Georgia. Morphological examination of seven ethanol-preserved specimens and six empty shells, combined with phylogenetic analysis, confirms its distinct taxonomic status. The genus is characterized by an elongate-conical shell with up to 5.2 whorls, trilobate penis morphology, and the absence of a bursa copulatrix in the female reproductive system.
