Description. Large equivalve carapace, sub-triangular in lateral view. Carapace slender posteriorly. Hmax at 1 / 6 anterior; Lmax at 1 / 4 dorsal; Wmax at 1 / 3 anterior and mid-height. Straight dorsal margin. Slightly convex ventral margin, oblique posteriorly. Ventral and dorsal margins converging posteriorly. Flattened anterior margin, regularly convex and forming an angle of about 120 ° with the dorsal margin. Posterior end very narrow (1 / 3 of Hmax) and regularly convex. Anterior part of the carapace clearly higher than the posterior one. Whole surface of the carapace, including free margins, papillose. Some nodes or slight spines, orientated posteriorly, pointing over the posterior margin of the valves. Curved ridge beginning in the antero-ventral part (at 1 / 3 anterior and 1 / 3 ventral) and pointing over the dorsal margin at mid-length.
