Description. Medium-sized very elongated carapace, biconvex in dorsal view, sub-rectangular in lateral view. Overlap of the larger LV over the RV at free margins of the carapace, especially anteriorly and posteriorly. Hmax at 1 / 4 anterior; Lmax at 2 / 5 ventral; Wmax slightly ventral. Lmax = 2 Hmax. Almost straight dorsal margin forming an angle of 120 ° with posterior margin and of 130 ° with the anterior one. Almost straight (very slightly convex) ventral margin. Ventral and dorsal margins almost parallel, slightly converging posteriorly. Well rounded anterior margin, more convex ventrally. Regularly convex posterior margin. Anterior part of the carapace slightly higher than the posterior one. Surface smooth.

Discussion. The general outline reminds C. perlonga (Kummerow, 1953). However, the bad preservation of our specimens makes the identification difficult. Occurrences. Middle Givetian (Fromelennes Fm, Flohimont and Moulin Boreux Mbs), Ardenne (Aisne section), Middle Givetian (Candás Fm, mbs A and B), Asturias (Peran-Perlora section).
