Resumen:
Species in Charopidae y Punctidae from the "Centro de Pesquisas e Conservacao da Natureza Pro-Mata (Brazil, Rio Grande do Sul) and Thiele1s collection are studied. The native species Rotadiscus amancaezensis (Hidalgo, 1869) Radiodiscus cuprinus Fonseca y Thomé, 2000, R. compactus (Suter, 1900) comb. nov. R. promatensis Miquel, Ramírez y Thomé, 2004, Lilloiconcha superba (Thiele, 1927), L. zulmae (Miquel, Ramírez y Thomé) comb. nov. L. gordurasensis (Thiele, 1927) and Radioconus pleurophorus (moricand, 1846) comb. nov., and the probably exotic Sinployea? goeldii (Thiele, 1927) were presented in the charopid samples from the CPCN Pro Mata; punctids were represented by Paralaoma servilis (Shuttleworth, 1852) and Paralaoma sp. A new species of Charopidae is described: Radiodiscus sanchicoensis sp. nov. It is a tiny shell with 60 to 75 axial ribs in the last whorl. The protoconch microsculpture of Lilloiconcha, Zilchogyra and Radioconus, with generic value, as well as their internal calcareous teeth. Several species and a genus (Lilloiconcha = Trochogyra) are placed into synonymy. The actual presence of some Patagonian species in southern Brazil is discussed; the only charopid reported to be present in Patafgonia and Brazil is R. amancaezensis. R. sanchicoensis is the dominant species n the CPCN Pro-Mata, followed by R. cuprinus.
