Description:
Shell flat, oval, divided by a +/- distinct and relatively broad girdle into an epitheca and hypotheca of approximately equal size; epitheca prolonged into a broadly based, short, blunt apical projection. Capsule oval with a short apical prominence. The wall of the capsule bears numerous thin perpendicular ledges which form a small-meshed supporting reticulum for the thin outer membrane. The meshes of the reticulum vary considerably in size and are usually widest towards the periphery. The pylome is broadly hoof-shaped and reaches the girdle.

Dimensions:
Holotype: 109 µm long, 95 µm broad, capsule 95x83 µm.
