Morphology

Size
Length 7.5-17 µm, width 3.2-3.9 µm (UK population), length 6.5-11.0 µm, width 3.3-3.8 µm (Wetzel et al. 2015).

Shape
Valves linear-lanceolate with rounded poles, frustules rectangular in girdle view.

Symmetry
Isopolar.

Striae
Some striae more or less parallel, others weakly radiate, 20 in 10 µm (UK population), 21-22 in 10 µm (Wetzel et al. 2015).

Axial area
Narrow linear, slightly widening towards central area.

Central area
Large rectangular subfascia, bordered by 2-3 short striae of different length.


SEM morphology
Striae biseriate, rarely uniseriate, areolae occluded internally by hymenes.

Raphe with drop-shaped proximal ends located distantly from each other, distal raphe fissures bent unilaterally onto mantle.

Internally a round depression is present at the valve apices.
