Figs. 8-10. Scanning electron micrographs of Gambierdiscus australes (RAV-92), sp. nov. Figs. 8, 9. Cells round to ellipsoid. The cell surface is smooth with scattered small pores. Fig. 8. Epithecal view. The Po plate is oriented ventrally. Fig. 9. Hypothecal view. The Ip plate, long and narrow, occupies 30% of the hypotheca width. Fig. 10. The Po plate is a broadly ellipsoid plate, with fish-hook-shaped apical opening surrounded by 31 pores.
