From editor or global species database
Diagnosis Medium to large sized ornamented Rotalispira. It is composed of at least three trochospiral whorls consisting of 11e13 chambers in the last whorl. Chambers gradually increase in size throughout ontogeny. Chamber periphery keeled. Dorsal side slightly convex, ventral side plano-concave. Septa slightly dorsally curved. Dimorphism not observed. Proloculus diameter is around 88 mm. Shell diameter is 1.2-1.3 mm, while shell thickness is about 0.8/0.9 mm; the D/H ratio is almost 1.5. Coarse pores are about 18 mmin diameter. The umbilical side hosts very long and markedly oblique folia, sometimes heavily bent at the contact with foliar plies. Specimens exhibit strong ornamentation in both sides. The dorsal side is represented by thick spikes and by densely packed foliar piles in the ventral side.
