This paper brings a contribution to the distribution of genus Stagnicola Jeffreys, 1830 and Catascopia Meier-Brook & Bargues, 2002 in the Czech Republic. Occurrence of four species has been confirmed in the Czech Republic so far. Two species – Stagnicola corvus (Gmelin, 1791) and S. palustris (O.F. Müller, 1774) (including S. turricula (Held, 1836)), are widespread and common especially in lowlands along bigger rivers (Labe, Ohře, Morava, Dyje, Odra). Occurrence of S. fuscus (Pfeiffer, 1821) is restricted to the territory of the north-western part of Bohemia and Catascopia occulta (Jackiewicz, 1959) is a rare species with only two known sites.
