Abstract

Information on the distribution of Anisancylus Pilsbry, 1924 in South America is provided. For first time, we recorded A. dutrae (Santos 1994) in Minas Gerais state and 2 new localities in northeastern Brazil. Anisancylus obliquus (Broderip & Sowerby, 1832) is widely distributed in Chile, Peru, central and southern Argentina, Uruguay and southernBrazil while A. dutrae is restricted to Brazil. This freshwater genus shows a disjunct distribution in South America that could be explained by tectonics and evolution of the basins. To understand this peculiar distributional pattern, additional studies should be performed combining biogeographic and phylogeographic analyses.
