Shell large, spatulate to elongate egg-shaped, slightly ventribiconvex in longitudinal profile and slightly to moderately (rarely strongly) convex in cross-section. Anterior valve margin generally flattened in larger specimens but evenly rounded in small specimens. Shell generally without shoulders and widest at 41–69% of valve length. Valves about 10–13% as deep as they are long and deepest at 30–33% of valve length. L/W ratio 1.12–1.99 (

Central muscle scars subcircular or transversely oval, about 5–7% as long as valve and located at 40–50% of valve length. Anterior lateral muscle scars located at 55–60% of valve length.

Flexure lines rather weak, nearly straight or bending anteriorly, defining small triangular inner parts of propareas. Pedicle groove moderately deep and sharply defined, widening from 7–8% of valve width to 9–10% of valve width. Pedicle groove connected to valve floor by short ridge extending anteriorly from groove. Pitting and striation of valve floor like that in dorsal valve. Visceral area generally with weakly impressed muscle scars.
