Description

Valves are lanceolate, with apices are broadly rounded, but not protracted. The axial area is narrow and straight, widening to form a rounded to sometimes nearly rectangular central area. The raphe is straight and filiform, with external proximal raphe ends dilated slightly and rounded. Distal raphe ends are hook-like. Striae are distinctly lineate and radiate along most of the valve, becoming parallel to convergent at the apices.
