The single individual collected from the upper Bathonian of Luc­sur­Mer does not permit a detailed description of its internal features, nor of its intraspecific variation.

Considered to be planktonic, Recent members of Cypridina (often phosphorescent) have a noncalcified carapace ( Moore 1961). However, the species observed at Luc­sur­ Mer shows a contour typical of the genus, with the anterodorsal angle directed downwards in the direction of the rostrum and a pointed posterodorsal extremity, hence its assignment to Cypridina . The lateral surface is reticulated, with the exception of the median portion. A weak costulation is seen on the anterior region.

Size: Length = 0.79 mm, height = 0.40 mm

Distribution

This genus, known from Recent settings, was cited by Apostolescu (1955) from the Lutetian (middle Eocene) of the Paris Basin. No member of the genus has been recorded from the Jurassic so far.
