Morphology
Size
10-15 µm long, 3-5 µm wide (Blanco et al. 2012); 10.5-12.5 µm long, 3-4 µm wide (UK population).
Shape
Valves linear-elliptic to linear-rhombic with non- or hardly protracted rounded ends.
Symmetry
Isopolar, bilaterally symmetrical.
Striae
Striae slightly radiate in central part of valve, becoming parallel towards apices, 15-21 in 10 µm (Blanco et al. 2012), 20 in 10 µm UK population). Areolae not discernible in LM.
Axial area
Narrow, linear.
Central area
Rectangular, transapically extended, sometimes asymmetrical, bordered by two shortened central striae.
Raphe
Raphe straight, filiform; central raphe endings positioned close to each other.
SEM morphology
Distal raphe endings not or slightly undulating and deflected.
Striae uniseriate with slit-like mostly apically, sometimes transapically elongated external areola openings.
