A new genus, Hatumia, is designated for two species of Oestophora: Hatumia riffensis (Ortiz de Zárate, 1962) and Hatumia cobosi (Ortiz de Zárate, 1962) based on new anatomical evidence and a review of the literature. A third new species, H. pseudogasulli, is described from Andalusia (southern Iberia), and also belongs to this new genus. H. gasulli and H. pseudogasulli n. sp. have quite similar shells, occupy the same ecologic niche, but have different distributions with the exception of a small contact zone where they live together. The diagnosis of the genera Oestophora Hesse, Gasulliella Gittenberger, Gasullia Ortiz de Zárate & Ortiz de Zárate and Suboestophora Ortiz de Zárate is provided.
