in diameter, short cylindrical in girdle view with several intercalary bands. Valve face is nearly flat. The valve center has one-several areolae surrounded by hyaline ring, rarely it is structureless. Central area contains loculate areolae with internal domed cribra and external foramina, arranged in more or less short radial rows (from 2 to 17 small areolae in row). Central area fultoportulae have never been observed. The striated zone occupies 1/2 to 3/4 the length of the valve radius. Striae,

, are radial, of unequal length, slightly undulate towards the center of the valve. They consist of two rows of small puncta on the valve face surface and of three-five small puncta on the valve margin. The striae are divided by costae dichotomously branched from the central area towards the valve margin. Alveolae are complex and simple. Marginal fultoportulae with three satellite pores are located on all recessed costae within marginal chambers. They are represented by small openings externally. One-several raised rimoportulae are positioned also on the recessed costae internally. They are marked by small round apertures on the external valve surface. Solid conic spines are present irregularly at the valve face/mantle junction.
