. The combination of its diamond-shaped outline with slightly inflated valve, and a strong posterior radial sulcus that extends to the posterior ventral margin serve to separate this species from
, although these features could be an artifact of preservation. Sculpture consists of numerous, slightly irregularly-spaced, co-marginal lamellae, with wide to moderate interspaces. The lunule, ligament, and escutcheon were not observed. This species appears most similar to the western Atlantic species
