It was reranked as Manzonia (Alvinia) by Kowalke and Harzhauser (2004).
It was assigned to Rissoidae by McLean and Coan (1996); to Neotaenioglossa by Sepkoski (2002); and to Manzonia by Kowalke and Harzhauser (2004).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. Kowalke and M. Harzhauser 2004 | 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 Paleo− gene, 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. |
