FIGURES 5–. SEM images of Craspedostauros laevissimus (sample 11). 35. External valve view showing the distal raphe endings and the curved central raphe endings. Note the areolae, clearly having one, or no central pore (arrows). 36. External valve view of one apex with bent, and the second apex with almost hooked distal raphe ending. 37. Close up of the central area of the same valve, showing that no central pores are present in cribrate areolae. 38. Close up of the apex of the same valve with the distal raphe ending and areolae. 39. External valve view with bent distal raphe endings. 40. Close up of the central area. Arrows showing the presence of areolae with no central pore or with one central pore, and four or five peripheral pores. 41. Close up of the apex of the same valve showing a cribrate areola with two central pores (arrow). Note also the presence of areolae with four or five peripheral pores, but lacking a central pore, or having only one central pore (black arrows). Scale bars = 5 μm (Figs 35, 36, 39); 1 μm (Figs 37, 38, 41).
