FIGURES 64–71. SEM images of Australoneis frenguelliae comb. nov. 64–65, 67, 69 from sample LPC 15910 (untreated); 66, 70–71 from sample LPC 15908 (treated); 68 from sample LPC 15911 (untreated). RV internal views. 64. Valve with partially broken RVVC, open at one pole (arrow). 66. RV showing raised axial structures and marginal virgae. 68. Tilted valve showing flat virgae at mid-valve and more raised marginal virgae, more prominent towards the margin (arrows). 65. Detail of raised axial structure and marginal virgae. Note undulated RVVC with fimbria-like undulations attached to the virgae (arrowheads) and a second, flat copula (arrow). 67. Detail of valve margin showing broken, hollow RVVC (arrowhead) with "fimbriae" attached to the raised virgae (arrow). 69. Round areolae occluded by hymen perforated by radial slits. 70. Detail of the valve apex showing distal raphe ending with prominent helictoglossa. 71. Detail of the prominent central nodule showing proximal raphe endings bent in opposite directions. Scale bars: 200 nm (Fig. 69), 1 µm (Figs 65, 67, 70–71), 5 µm (Figs 64, 66, 68).
