- Valves dorsiventral with convex ventral margin at mid-valve
- Terminal nodules distinct
- Single stigmoid in line with middle dorsal stria
- Ventral striae radiate to convergent, unevenly spaced
- Dorsal striae radiate
Valves with a broadly rounded dorsal margin and a linear ventral margin that expands at the center. Dorsal striae are radiate throughout, and ventral striae are radiate to convergent. Dorsal striae are regularly spaced, while ventral striae vary in density and length across the apical axis. Terminal nodules are thick and distinct. A single stigmoid occurs in line with the central dorsal stria.
