Diagnosis Medium-sized, high trochospiral shell. The dorsal side is highly convex, unornamented and perforated by pores of wide calibre. Chamber walls are particularly thick. The umbilical side is flat to slightly convex, and occupied by a massive plug surrounded by a narrow spiral interlocular space transformed into a spiral canal. The periphery is acute with a more or less pronounced imperforate keel. Folia are relatively wide and imperforate and never overlap the central part of the plug. The foliar chamberlet is separated from the main chamber lumen by the umbilical plate, which forms a rectilinear sutural notch. An interlocular intraseptal canal is present along the septa, which is slightly curved and thickens near the aperture. The trochospire consists of up to 3 whorls of trapezoidal chambers. There are at least 8e9 chambers in the last whorl. The average diameter of the proloculus is 30e35 mm. Shell diameter varies from 0.9 to 1 mm, while the height varies from 0.63 to 0.71 mm. The average D/H ratio is 1.42. Dimorphism not observed. [details]
