Morphology
Size
32.5-48.5 µm long, 8.5-10.0 µm wide (UK population).
Shape
Valves linear-elliptic, margins tapering slightly and gradually to broadly rounded or cuneate apices.
Symmetry
Isopolar, bilaterally symmetrical.
Striae
Striae radiate, becoming parallel towards valve ends, and convergent at apices, 10.5-12.5 in 10 µm.
Axial area
Narrow, linear, slightly widening towards central area.
Central area
Central area rounded, rhombic or oval bordered by several shortened striae of different length.
Raphe
Raphe slightly lateral with expanded central endings, slightly deflected to the same side, located slightly distantly from each other; terminal fissures hooked close to the apices.
