Description
Size: Diameter 15-110 µm.

Areola pattern of valve center; marginal spines.
Girdle view: Depending on cell diameter, pervalvar axis from one-sixth to longer than the length of the diameter. Valve face flat; mantle low and rounded. Connecting thread about twice the cell diameter.
Valve view: Areolae in curved tangential rows (eccentric structure) with a tendency of fasciculation. Central strutted process adjacent to a central areola surrounded by a ring of seven areolae; scattered strutted processes on valve face; two marginal rings of strutted processes with short external tubes; one ring of pointed spines further away from valve margin.
