The carapace lacks any hinge or separate dorsal plates, as visible in slightly obliquely compressed specimens. The lower margin frequently shows a narrow strengthening belt, probably a little thicker than the rest of the cuticle, perhaps representing a doublure. In specimens PIN 4983/20 and 4983/7, minute sparsely distributed denticles are recognizable near the posterior end of the carapace at its margin. Two somewhat more prominent spines arm the ventro-posterior lobe of the carapace in PIN 4983/1d. The anterior end of the carapace narrows parabolically and is a little pointed, as shown by PIN 4983/8a. The carapace length in the studied material ranges from
