If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. J. Finlay 1939 | Test rotaliform, more or less planoconvex, with a strong tendency to develop a peripheral flange. Sutures sloping back at sharp angle dorsally, somewhat markedly sinuous basally. Umbilical area usually with a prominent boss of clear material. Aperture a linear slit with a sharp, projecting outer edge, extending from plug almost to periphery, where it suddenly turns backwards into the flange, like Pulvinulinella. In New Zealand, specimens are common in the Upper Bortonian and apparently less so in the Lower Bortonian. |
