| Summary: | FIGURES 23–32. Orthoseira groenlandica Goeyers, Kochman-Kędziora & Van de Vijver, sp. nov. SEM pictures taken from the holotype material (BR-2801, Qeqertarsuaq, Greenland, sample DM27). 23. Frustule in girdle view showing the structure of the cingulum. 24. Entire girdle band. 25. SEM external view of a valve in oblique view showing the step in the mantle (arrows). Fig. 26. SEM external view of a valve in oblique view lacking the step in the mantle. 27–29. Three external views of an entire valve. Note the typical siliceous scales in the valve center, the marginal ring of ridges and the scattered, short teeth-like spines. 30. SEM external oblique detail showing the irregular valve face ornamentation with papillae, thin spines and siliceous plates in the valve center. 31. SEM external detail of the marginal spines. Note the granulate surface structure of the girdle band. 32. SEM external detail of the surface structure in the central area obscuring the view on the carinoportulae. Scale bars = 10 µm (Figs 23–31), 1 µm (Fig. 32).
