Morphology
Size
14-30 µm long, 6-8 µm wide (Levkov & Ector 2010).
Shape
Valves linear-lanceolate with slightly protracted broadly rounded to slightly truncated poles. Weakly convex dorsal and ventral margins, the latter with slight central inflation.
Symmetry
Dorsiventral, isopolar.
Striae
Striae slightly radiate, becoming more strongly radiate near poles on dorsal side.
Central area
Central area a broad, unilateral fascia extending to ventral margin, small area dorsally bordered by a shortened stria. One stigma located between proximal raphe endings.
Raphe
Raphe slightly lateral with tear drop-shaped central pores; distal fissures ventrally curved, extending onto mantle.
SEM morphology
Striae biseriate with C-shaped areola openings.
