  1. Dorsal undulations broad
  2. Valves large
  3. Transapical striae nearly parallel

Valves are large and dorsi-ventral, with broad biundulate dorsal margins. Transapical striae nearly parallel, becoming more dense near the apices. The ends are capitate, especially in larger valves. Small undulations are present on the ventral side, which coincide with the proximal raphe ends.
