Description
Size: Apical axis 9-84 µm.

Color: Yellow brown.

Colonies are long, straight and stiff. Cells rectangular in girdle view with valve face concave, mantle high. Foramina narrow. Valve corners touching those of adjacent cell. Apertures slit-like to broadly lanceolate. Setae long, thick, straight, without basal part. Sibling setae fused for a length several times their diameter and then diverging in pervalvar direction. Terminal setae thicker than the others, initially divergent, then bent, becoming parallel to chain axis. Setae cross over at the colony margin. Several small chloroplasts are present. In SEM valves are elliptical with hair-like filaments visible in apical areas of the intercalary valve mantle. The rimoportula is a small tube-like structure, eccentrically located. Intercalary setae fuse for a distance of 10–20 µm before diverging. Setae are polygonal in cross section (6–8 sides), perforated with poroids, bearing small spines. Resting spores unknown. Central process with no distinct protrusion on the outside and a labiate structure on the inside.
It is a phytosynthetic species.
