Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Yu. Parkhaev 2001 | The shell is cap-shaped, evenly expanding from the apex to the aperture, strongly laterally compressed, relatively high. The apex is pointed, hooked and displaced posteriorly. The aperture is extremely narrow, oval, its lateral margins are slightly convex. The partial train lies below the apex. Ornamentation is represented by concentric ribs. | |
| M. J. Vendrasco et al. 2011 | Highly laterally compressed, tall univalve with a sub-triangular lateral profile, slight coiling (about 1/8 to just over 1/4 one whorl), concave sub-apical margin (embayment) that borders an angular to flat sub-apical shelf. |
