  2. Apices short, rostrate
  3. Striae 16-19 in 10 µm

Valves linear-lanceolate with short, rostrate apices. Axial area narrow, straight, expanded to form a narrow, sometime narrowly elliptic central area. Striae are punctate, parallel in the middle, becoming convergent at the apices. Maximum valve width is less than 10 µm.
