Description
Summary:FIGURES 5 –56. SEM images of Craspedostauros confusus sp. nov. from the type population (sample 14). 52. Internal valve view. 53. Close up of the central area internally, showing the narrow stauros on a wider hyaline area, the central raphe endings with double helictoglossa and the rounded to elliptic internal areolar openings. Arrow shows an areola with seven central pores, visible internally. 54. Close up of the apex with the pores of cribrate areolae internally (arrows). 55. Close up of the central area of another valve of the same population, showing once again the narrow stauros, the internal central raphe endings with double helictoglossa and rounded internal areolar openings. 56. Close up of the apex with rounded to elliptic and even somewhat irregular in shape internal areolar openings. Scale bars = 5 μm (Fig. 52); 1 μm (Figs 53–56).
