Morphology
Size
20-52 µm long, 5-7 cm wide (Lange-Bertalot 2001).
Shape
Valves lanceolate with subrostrate ends.
Symmetry
Isopolar, bilaterally symmetrical.
Striae
Striae radiate and curved in the central part of the valve, convergent near the poles. Areolae discernable to some degree in LM, ca. 35 in 10 µm (Reichardt 1988).

Central area
Small, irregular, bordered by shortened striae of different length, 11-17 in 10 µm.
Raphe
Straight, filiform, central pores placed close to each other.
