| Popis: | Four new species of the pyramidellid Odostomiinae from Brazil are described: Chrysallida conifera sp. nov., characterized by a small and regularly conical shell with prominent nodules; Parthenina biumbilicata sp. nov., characterized by a deep and wide umbilicus and a regularly increasing aperture diameter at the protoconch, which bears a small circular umbilicus; Eulimastoma franklini sp. nov., which is very similar to Eulimastoma dydima (Verrill & Bush, 1900) but has a prominent helicoid protoconch; Eulimastoma exiguum sp. nov., similar to Eulimastoma weberi (Morrison, 1965) but without spiral ridges. Fargoa diantophila (Wells & Wells, 1961) and Chrysallida nioba (Dall & Bartsch, 1911) are reported from the southwestern Atlantic for the first time. |
