Morphology
Size
12-14 µm long, 2.5-3.0 µm wide (UK population), 11-14 µm long, 3-4.5 µm wide (Lange-Bertalot et al. 2011).
Shape
Valves arcuate with strongly convex dorsal margin, slightly concave ventral margin and small, protracted, capitate poles.
Symmetry
Dorsiventral, isopolar.
Striae
Radiate, 20-22 in 10 µm (UK population), 15-21 in 10 µm (Lange-Bertalot et al. 2011), shorter striae sometimes intercalated at dorsal margin.
Raphe
Raphe located on mantle close to valve face/mantle junction, short terminal fissures curving onto valve face near apices, terminating approximately in centre of poles.
