Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H.M. Bolli et al. 1957 | Test free, robust, early portion planispiral and similar to Hastigerina, later with biserially arranged chambers continuing to spiral in the same plane, biumbilicate, periphery broadly rounded; chambers globular to ovate and only a few pairs arranged as in Cassidulina to each whorl of the test; sutures distinct, depressed, radial to curved; wall calcareous, perforate, radial in structure, surface smooth to pitted; aperture interiomarginal, an extraumbilical arch alternating in position from one side to the next in successive chambers. |
