  1. Ventral margin convex
  2. Apices subrostrate
  3. Distal raphe deflected ventrally
  4. Striae radiate
  5. Apices curve to ventral side

Valves are nearly lanceolate, with subrostrate apicies. The ventral margin is convex. The distal raphe ends are deflected towards the ventral side and extend to the edge of the valve. The raphe is lateral, becoming reverse-lateral proximally. The proximal raphe ends are curved dorsally. Striae are radiate throughout the valve, may be parallel at the center. Apices curve to the ventral side.
