dc:description"FIGURES 3–8. LM images of the undulating external valve view of Giffenia koreana sp. nov. on the holotype (Figs 3–5) and isotype (Figs 6–8). Fig. 3, 4: The valve face focused on the slightly convex side. Fig. 5: The valve face focused on the slightly concave side, with an uneven central sternum positioned along the apical axis. Figs 6–8: The valve face observed on various focuses. Scale bar: 10 µm.";
dc:description"FIGURES 9–14. SEM images of Giffenia koreana sp. nov. featuring type materials. Fig. 9: A whole cell displaying the thin lip-shaped sternum (arrow), accompanied by numerous alveoli consisting of rows of pores. Fig. 10: The valve face with disrupted rows of pores and the thin lip-shaped sternum (arrow). Fig. 11: Side of the valve showing the continuous, whole raphe slit. Fig. 12: Internal valve face featuring the internal openings of the alveoli. Fig. 13: The valve face with a central thin lip-shaped sternum. Fig. 14: The alveoli with multiseriate pores on the external valve face. Scale bars: 10 µm for Figs 10–12, 14; 20 µm for Figs 9, 13.";
dc:description"FIGURES 15–19. SEM images of Giffenia koreana sp. nov. on the type materials. Fig. 15: A whole cell displaying the central thin lipshaped sternum (arrow), numerous alveoli, and raphe slit. Figs 16–19: A hyaline area between the raphe slit and the alveoli (arrow). Figs 17–19: Valve apex featuring a downturned raphe apex, and with curved alveoli (arrow). Scale bars: 5 µm for Figs 18, 19; 10 µm for Figs 15–17.";
