Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. Kowalke and M. Harzhauser 2004 | Mohrensterniinae are characterised by low−conical protoconchs usually comprising 2–2.75 whorls measuring 0.3–0.5 mm in maximum diameter with small embryonic shells (only species with indirect development are known). Protoconchs are characterised by fine spirally sculptured embryonic shells and larval shells which are smooth except for growth lines. The transitions from the embryonic shell to the larval shell and from the larval shell to the teleoconch are only slightly thickened and often indistinct. No marked sinusigera notch is present. |
