The species distribution data of the Meotian freshwater air-breathing mollusks of family Lymnaeidae at the Southern Ukraine are generalized. 15 types of Lymnaea belonging to the same genus (Lymnaea Lamarck, 1771), six subgenera (Lymnaea s. str.; Stagnicola Leach, 1830; Omphiscola Rafinesque, 1819; Radix Montfort, 1810; Peregriana Servain, 1881; Galba Schranck, 1803), nine sections (Lymnaea s. str.; Berlaniana Kruglov et Starobogatov, 1985; Stagnicola s. str.; Radix s. str.; Iraniradix Kruglov et Starobogatov, 1989; Cyphideana Servain, 1881; Ampullaceana Servain, 1881; Bouchardiana Servain, 1881; Galba s. str.) were recognized in the Lower Meotian (Central Black Sea area) and Upper Meotian (Kerch Peninsula) sediments of the Southern Ukraine.The new subspecies of subgenera Omphiscola – Lymnaea (Omphiscola) ovum kertshensis Kovalenko subsp. nov. is described from the Upper Meotian sediments of Kerch Peninsula.At present it is found that the “current” species of now living Lymnaea predominate in the Lower and Upper Meotian sediments of the Southern Ukraine, while besides the “current” species of Lymnaea the distinguishing species Lymnaea (Omphiscola) maeotica Kovalenko, 1990, is recognized in the Lower Meotian rocks as well as the new subspecies of subgenera Omphiscola – Lymnaea (Omphiscola) ovum kertshensis Kovalenko subsp. nov. is marked.Presence of both the distinguishing species Lymnaea (Omphiscola) maeotica Kovalenko, 1990, in the Lover Meotian rocks and the new subspecies of subgenera Omphiscola – Lymnaea (Omphiscola) ovumkertshensis Kovalenko subsp. nov. in the Upper Meotian ones allows to separate the Lower and Upper Meotian sediments from each other for the continental section of the Meotian Stage of the southern Ukraine.
