Mumladze, L., Bikashvili, A. Japoshvili, B., Anistratenko, V. V. — First records of invasive bivalve freshwater mollusc species Mytilopsis leucophaeata (Conrad, 1831) and Corbicula fl uminalis (O. F. Müller, 1774) in Georgia are reported. No native or alien extant dreissenid species have ever been recorded form this region so far. A fi nding of C. fl uminalis in Georgia is also a new record for the country though this species inhabits the rivers of adjacent Azerbaijan. Apart from two mentioned bivalve molluscs three non-indigenous gastropod species are registered from Georgia: freshwater Ferrisia californica (Rowell, 1863) and Physella acuta (Draparnaud, 1805) and land snail Eobania vermiculata (O. F. Müller, 1774). Key words: alien species, Mollusca, Dreissenidae, Cyrenidae, South Caucasus. Introduction Ponto-Caspian region is a major source of macroinvertebrate invasions worldwide (Bij de Vaate et al., 2002).
