): Valves linear with gibbous central part and broadly rounded, non-protracted apices. Valve dimensions (n = 50): length 13.532.5 μm, width 35.5 μm. Axial area linear, fairly wide. Central area round, slightly widened due to the shortening of the central striae, never forming a fascia. Raphe filiform, straight with simple straight proximal and distal endings. Striae parallel throughout the entire valve, not interrupted in the middle.
