Dimensions

RV: L = 256–319 µm; H = 170–197 µm; H/L = 0.6–0.63.

LV: L = 271–301 µm; H = 145–172 µm; H/L = 0.57.

Occurrence

Romanian Continental Shelf, Black Sea, Rhaetian, Upper Triassic (this paper).

Remarks

These very small specimens are characterized by a strong overlap of LV around the free margin of RV, lateral surface of both valves entirely tuberculate, lack of marginal compression, and a lack of caudal process, sulcus or lateral extensions. They may correspond to a new genus but the material is still too scant to confirm this hypothesis and fully appreciate the diagnostic characters of this possibly new genus.
