Valves linear, arcuate with parallel margins. Ventral margins concave, dorsal margins convex. Apices slightly protracted and slightly expanded, rounded to bluntly rounded to slightly rectangular. Helictoglossae on the terminal nodules visible under LM as a small dot on the ventral margin. In girdle view, cells thin, isopolar, constricted in the middle portion. Striae parallel and equidistant, becoming radial towards the apices and always visible in LM. Valves measured in the present study (n = 18) with the following dimensions: length 19.5-31.0
