. Valve face is distinctly divided into two zones: a marginal alveolate zone and a transversely undulate, elongated areolate central area. A narrow, irregular hyaline area separates these two zones. Central area is elliptical, symmetrically undulate: elevated and depressed parts are almost equal. Areolae with internal domed cribra and external foramina are arranged mainly irregularly. One valve face fultoportula with two satellite pores internally and a round thickened aperture externally can be seen within the central area, rarely can be absent. Striae,

. Marginal fultoportulae have three satellite pores internally and open by short tubes externally. They are positioned on all recessed costae within alveolar chambers on the internal valve surface. One or two rimoprtulae are sessile internally, and each is located on a costa between two alveolar openings in the pole area. Rimoportulae open by a round apertures externally. Spines can be present on the valve face/mantle junction, but they are often broken.
