Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. Kowalke and M. Harzhauser 2004 | The subgenus Manzonia differs from the subgenus Alvinia by teleoconch whorls narrowing towards the aperture, thus separated by deep sutures and by a teleoconch sculp− ture of prominent, rounded, strongly opisthocline axial ribs crossed by much weaker spirals. |
