Abstract. A new genus of stygobiont hydrobiid snails, endemic to Georgia, is described. Sitnikovia gen. nov. includes two species: S. megruli sp. nov. and S. ratschuli sp. nov., known only from their type localities (Garakha and Sakishore caves). The data of shell characters, penial morphology, and radula of the new genus are provided.
Key words: aquatic malacofauna, stygobiont gastropods, taxonomy, Transcaucasia, Littorinimorpha, Hydrobiidae, new genus, new species
