Raphe straight, axial area narrow; central area transversely extended. Lateral hyaline areas broad in the middle of the valve, narrowing towards apices and terminating at either side of the base of the apex, slightly deflected to the sides.
Remarks: Striae density is slightly higher than those given elsewhere (10-14 in 10 µm).
Widespread marine species.
