Original description medium-sized, lamellar perforate trochospiral shell. Low convex dorsal side un-ornamented and showing lamellar thickening due to the formation of successive lamellae during ontogeny. The periphery of the shell is angular and keeled. Ventral side convex and largely occupied by piles and funnels. The massive funnelled plug is surrounded by a spiral interlocular space (spiral canal). The trochospire consists of 2-2.5 whorls and is composed by slightly rectangular chambers, which are higher than wider. There are at least 12-13 chambers in the last whorl. The small proloculus is 30 mm in diameter. Shell diameter varies from 1.1 to 1.2 mm, while the height varies between 0.71 and 0.77 mm; the average D/H ratio is approximately 1.46. The intraseptal interlocular space is present along the straight septa. The spiral canal is restricted by the successive tooth-plates. [details]
