Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. A. Darragh 1989 | The systematic position of the genus itself is in doubt since the information available on the anatomy of Notovoluta precludes placement in any of the existing subfamilies. Weaver and du Pont (1970), the only authors to consider its systematic placement, placed it in the Scaphellinae near Amoria, without any explanation for their action. The anatomy, so far as it is known (Darragh, 1983), has no close affinity with Amoria. Until more information is available it does not seem appropriate either to errect a new subfamility for the reception of the genus, or to attempt to place it in an existing subfamily. |
