Description

The valves are rhombic-elliptical with broadly rounded apices, 29-33 µm long and 14-15 µm broad. The axial area is narrow. The central area forms a transverse fascia dilating towards the margins of the valve. The raphe is straight with rather dense central pores. The terminal fissures are deflected in the same direction. The transapical striae, 9-10 in 10 µm, are extremely radiate towards the middle of the valve, more or less sigmoid, and towards the apices parallel or faintly convergent.
