  3. Apices broadly rounded
  4. Striae distinctly lineate

Valves are lanceolate, with broadly rounded apices. The raphe is straight and filiform. The external proximal raphe ends are slightly dilated and rounded. The distal raphe ends are hook-like. Striae are distinctly lineate and radiate along most of the valve, becoming parallel to convergent at the apices.
