): Valves narrowly linear-clavate, asymmetrical to the transpical axis. Headpole slightly protracted to not protracted, rounded; valve narrows towards the rounded footpole. Length 10–16 μm, breadth 2.4– 3.7μm (
were measured based on the LM and SEM observations). Axial area linear, narrow, central area small, irregular in shape. Striae radiate in the middle of the valve and alternating in length, becoming convergent near the apices, 13–16/10μm. Stigma indistinct, positioned at the end of a central stria.
