Subgenus Alvinia Monterosato, 1884

Type species: The recent species Alvania weinkauffi (Mohrenstern ms.) Weinkauff, 1868 from the Mediterranean.

Remarks.— Flemellia Nordsieck, 1972 , which had been introduced as a new name for Taramellia Seguenza, 1903, Seguenziella Sacco, 1904 and Flemingia Jeffreys, 1884 with the type species Turbo zetlandicus Montagu, 1803 , Recent, from the NE Atlantic (Wenz 1938−1944: 616, fig. 1717), represents a synonym. Alvinia differs from Alvania by its well−rounded base and by the roundish, thickened aperture with duplicated peristome lacking interior teeth. Ponder (1985) mentioned that M. ( Alvinia ) probably had diverged from Alvania in the Paleogene, because species from the Eocene of the Paris Basin are similar to recent congeners from the eastern Atlantic and from the Mediterranean, and only differed in peristome morphology, which was not duplicated.
