Whole valve view showing striae in trough–like openings in the center, but with individual areolae at the dorsal and ventral margins. Scale bar = 1 μm. 32, 33. Center of the valve showing areolae in one (Fig. 32) or two rows (Fig. 33) at the dorsal and ventral portions of the valve as well as in trough-like lines in the center. Scale bars = 1 μm. 34.
