  1. Valves lanceolate
  2. Apices protracted
  3. Apices with radiate or parallel striae

Valves are lanceolate and 8-11 µm in width. Apices are narrow and protracted, except in small specimens. The striae near the apices are variable; they may be radiate or parallel. The striae near the center of the valve are straight, rather than bent.
