- Valves linear to linear-lanceolate
- Striae radiate, somewhat curved
- Central area small, surrounded by shortened, less dense striae
- Apices rounded, rostrate to subcapitate
Valves are linear to linear-lanceolate, with rostrate to sub-capitate broadly rounded apices. Striae are radiate and curved, becoming nearly parallel at the apices. Striae are considerably less dense at mid-valve, and are occasionally shortened.
