Valves linear, linear-lanceolate, or lanceolate, narrowing to rounded or protracted rostrate or subcapitate ends. Frustules rectangular in girdle view.

Isopolar, isovalvar, bilaterally symmetrical.

Striae more or less parallel, broad, sometimes shortened, biseriate with round aroelae or consisting of a row of elongate, complex areolae. Areolae externally occluded by cribra. Striae separated internally by distinct ribs.

Axial area linear, narrow to wide.
