A study of 485 specimens of Geostiba Thomson, 1858, 482 of which were collected during three field trips to West Georgia conducted in 2021, yielded eleven species, two of which are described and illustrated: Geostiba (Sibiota) brevifistula spec. nov. (Georgia: Kvemo Svaneti) and G. (S.) egrisica spec. nov. (Georgia: Samegrelo-Zemo Svaneti). Both species belong to the G. bituberculata group. Geostiba (Geostiba) sororcula Assing, 2001, a species previously known only from Northeast Turkey and Armenia, is reported from Georgia for the first time. The distributions of five species are mapped. The Geostiba fauna of the Caucasus region sensu lato is now represented by a total of 50 species, 30 of which belong to the subgenus Sibiota Casey, 1906.
