“…Una especie cuya identidad permanece incertae sedis es Stephanoda iheringi Ancey, 1899, ubicada como Radiodiscus por Fonseca & Thomé (1994b), aunque sin mención de haber estudiado ejemplares de la serie tipo original (cita reiterada por Salgado & Coelho, 2003).…”

Biodiversity and taxonomy of punctoid micromollusks from southern Brazil, with description of a new species of Radiodiscus from the «Mata Atlántica» (Atlantic Rain Forest) (Mollusca, Gastropoda, Pulmonata). Species in Charopidae and Punctidae from the «Centro de Pesquisas e Conservação da Natureza Pró-Mata (CPCN Pró-Mata)» (Brazil, Rio Grande do Sul) and Thiele's collection are studied. The native species Rotadiscus amancaezensis (Hidalgo, 1869), Radiodiscus cuprinus Fonseca & Thomé, 2000, R. compactus (Suter, 1900) comb. nov., R. promatensis Miquel, Ramírez & Thomé, 2004, Lilloiconcha superba (Thiele, 1927, L. zulmae Miquel, Ramírez & Thomé, 2004 comb. nov., L. gordurasensis (Thiele, 1927, and Radioconus pleurophorus (Moricand, 1846) comb. nov., and the probably exotic, Sinployea? goeldii (Thiele, 1927) were present in the charopid samples from the CPCN Pró-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 75 to 60 axial ribs in the last whorl. The protoconch microsculpture of Lilloiconcha, Zilchogyra and Radioconus, with generic value, is studied, as well as their internal calcareous teeth. Several species and a genus (Lilloiconcha = Trochogyra) are places into synonymy. The actual presence of some Patagonian species in southern Brazil is discussed; the only charopid reported to be present in Patagonia and Brazil is R. amancaezensis. R. sanchicoensis is the dominant species in the CPCN Pró-Mata, followed by R. cuprinus.

Se presenta una lista parcial de gasterópodos terrestres Punctoideos del "Centro de Pesquisas e Conservação da Natureza Pró-Mata" (São Francisco de Paula, Estado de Rio Grande do Sul, Brazil) (CPCN-PM). Esta lista incluye siete especies, dos de ellas son nuevas. El CPCN-PM se localiza entre los 600 y 950 m de altitud; presenta clima templado superhúmedo a húmedo, lluvias de 2.250 mm anuales y temperatura promedio anual de 14,5ºC; están presentes tres regiones fitoecológicas principales, floresta ombrófila mixta, floresta ombrófila densa y sabana. Los taxones hallados son: Rotadiscus amancaezensis (Hidalgo, 1869), Lilloiconcha tucumana (Hylton Scott, 1963), Radiodiscus cuprinus Fonseca & Thomé, 2000, Radiodiscus tenellus Hylton Scott, 1957, Radiodiscus promatensis sp. nov., Zilchogyra gordurasensis (Thiele, 1927) y Zilchogyra zulmae sp. nov. La conchilla de R. promatensis sp. nov. es muy pequeña, casi plana, con ombligo muy desarrollado, abertura reniforme, con estrías espirales en la teleoconcha y 58-62 costillas axiales en el último anfracto. La conchilla de Z. zulmae sp. nov. es troquiforme alta, con cinco anfractos con fuertes y espaciadas costillas axiales (25-38), ombligo amplio y perspectivo y abertura subcircular angulosa. La fauna de gasterópodos carópidos del CPCN-PM tiene tres especies conocidas sólo del área (R. cuprinus, R. promatensis sp. nov. y Z. zulmae sp. nov.), una, que se distribuye también en Paraguay (R. tenellus) y tres (L. tucumana, R. amancaezensis y Z. gordurasensis), comunes a otras áreas de América del Sur, principalmente la región de las Yungas.
