Frustule

Description
Size: Diameter 140-280 µm.

Girdle view: Cells about as high as wide. Valves convex, slightly concave in the center.
Valve view: Central rosette of larger areolae more or less distinct. Areolae in radial and spiraling rows. Cribra visible with light microscopy. At about half radius an irregular ring of interstitial meshes (probably labiate processes). One marginal ring of processes, visible with light microscopy, with hyaline lines bordered by one row of slightly larger areolae on either side toward the valve center. Inside the marginal ring two larger processes with prominent external areolated protuberances, ca. 100˚ apart.
Distinctive features: Large external protuberances of the two larger marginal processes.
