Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. Vinn and N. Spjeldnæs 2000 | Ventral valve transversely semielliptical in outline, convex in the lateral profile, with the maximum width about at mid-length of the valve. Cardinal extremities obtuse, the anterior margin rounded, commissure rectimarginate. Costellae of equal size, evenly spaced. Concentric growth lamellae, preserved on anterior of the specimen (PMO 1 62.093), forming a well-developed imbricate sculpture.
Ventral interarea short relative to length, flat and apsacline. Delthyrium as wide as long, less than half covered by convex deltidium. Foramen is not clearly observable in any specimen studied, possibly very small, sealed and entirely apical.
