Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. R. Loeblich and H. Tappan 1986 | A genus of the Vaginulininae with broad subtriangular and flattened test, truncate and carinate periphery, and unornamented unornamented shell.
Psilocitharella differs from Vaginulina in the flattened rather than ovate section, and truncate rather than rounded periphery, and differs from Citharina in having a smooth rather than striate or costate surface, although topotype specimens of the type species show secondary overgrowths of granular calcite at high magnification. |
