. The ultrastructure of the external valve view shows a centrally located raphe situated in a narrow axial area (Fig. 23). Terminal fissures are deflected to the dorsal side of the valve at an angle of almost 90° (Fig. 23, 24). Apical pore fields (Figs 23, 24) are present bearing small simple poroids, not bisected by the distal raphe endings (Fig. 24). The proximal raphe endings are deflected to the dorsal side (Fig. 25). The transapical striae are composed of slit-like areolae with apically orientated foramina. There are 3–4 striae that are biseriate at the apices (Fig. 24).
