Morphology
Size
14-16.5 µm long, 4.5-5 µm wide (UK population).
Shape
Valves elliptic-lanceolate with protracted rostrate ends.
Symmetry
Isopolar, bilaterally symmetrical.
Striae
Striae weakly radiate in central part of valve, becoming parallel or weakly convergent towards apices, 12-14 in 10 µm (UK population). Areolae discernible in LM.
Axial area
Narrow, linear.
Central area
Small, transverse rectangular, or rounded, sometimes asymmetrical or inconspicuous, bordered by slightly or moderately shortened central striae.
Raphe
Raphe straight, filiform with expanded central and distal endings; central endings positioned close to each other, straight or slightly deflected, distal endings slightly deflected.
SEM morphology
Striae uniseriate with slit-like apically elongated external areola openings.
