Striae number was 22–28/10 μm at the center, and up to 25–34/10 μm near the apices on the raphe valve. On the rapheless valve, striae radiated along the middle portion and were nearly parallel near the apex, becoming denser toward the valve apices, as well as 26–30/10 μm in the middle and 30–35/10 μm near the apices.
