Width Range: 4-6 µm
Striae in 10 µm: 35-38

Description

Valves are linear to linear-lanceolate with parallel sides, except near the center of the side bearing the keel, which is concave. The apices are rounded and nearly capitate. The raphe is positioned excentrically, with a distinct central nodule. Fibulae vary in size and number 11-14 in 10 µm. Striae are resolvable and parallel. There are specimens in which the punctate nature of the striae is visible with LM.
