• Cyclotella hakanssoniae: Wendker (1991)
• Cyclotella caspia: Grunow (1878)

Solitary, more rarely cells join together to form colonies of 2-3 cells. In girdle view the cells appear drum-shaped, while in valve view they appear circular. From the centre of the valve to the margin identical striae are visible, and between the striae rimoportulae are visible. The central area is undulating and has fultoportulae. Around the margin of the cell, randomly arranged granules of silicon are visible.
