The valve face is flat to slightly concave and the mantle is quite high without a constriction near the margin. Each intercalary valve possesses two common, long and robust setae, and four short, thin and strongly spirally undulated setae (

). Common setae originate at the valve margin on two opposite sides of each valve, and join with sibling setae after a short basal part. They fuse for a rather long distance (ca. half of the valve diameter) and then diverge equally at an angle of ca. 30° from the apical axis, lying in the apical plane. Spiral setae also have a short basal part but they fuse at a single point and then extend perpendicular to the chain axis lying in the valvar plane (

). The aperture between adjacent cells is distinct, and appears to be elliptical in shape due to the most visible connection between two long sibling setae. Terminal valve possesses only two long common setae extended in the direction of the chain. The two terminal setae slightly differentiate in the curvature, one being more parallel to the chain axis while the other is first more widely curved and then becomes parallel with the same axis.
