  1. Dorsal margin broadly arched
  2. Apices broadly rounded
  3. Hyaline line at ventral margin

The dorsal margin is broadly arched, although the dorsal margin of smaller valves is more highly arched than the dorsal margin of larger valves. The apices are broadly rounded. The apices are usually unconstricted (not "set off"), but the largest valves may have slightly constricted apices. The striae are nearly parallel and are interrupted by a hyaline line at the ventral margin.
