Valve with four undulations on the dorsal side and with straight ventral margin. Ends slightly heteropolar, with one pole more protracted than the other, and both broadly rounded. The slope between the dorsal valve undulation and the pole is steeper near the more protracted pole. Valve face with an irregular rough surface. Length (31.5) 36.0–48.0 μm, width 9.0–13.0 μm. Striae coarse and irregularly distributed on the valve face, 5.5–7.0, rarely up to
