Semicells pyramidal with a broadly rounded apex and convex sides. Sides crenate with about 18 crenations that slightly increase in width from the sinus to the apex. On the inner side of the margin there are some two additional series of flattened verrucae visible. The centre of the semicell is distinctly punctate. Lateral view elliptic with a shallow obtusely angled constriction. Apical view elliptic-rhombic. Chloroplast with a single, central pyrenoid. Dimensions: cell length 38–41μm, cell breadth 26–27μm, cell thickness 19–20μm, breadth of isthmus 15–17 μm.</paragraph>
