FIGURES 8–15 in Small-sized and discoid species of the genus Cocconeiopsis (Bacillariophyta) on Holothuria atra (Juan de Nova, Mozambique Channel)
FIGURES 8–15: Cocconeiopsis juandenovensis sp. nov. (SEM) from "JDN2 Holothuria atra". Fig. 8: External view of central raphe endings, curved in opposite side. Fig. 9: Note elevated virgae and well identifiable areola at each end of stria. Fig. 10: External view of one apex and terminal raphe ending. Fig. 11: marginal row composed of one areola toped by a horse-shoe shaped marginal areola. This marginal group of areolae is well separated from the rest of the stria by a hyaline rim (arrow). Fig. 12: Note short slits randomly scattered on stria with no well identifiable areolae. Fig. 13: Detail of horse-shoe shaped marginal areolae (arrow). Figs 14, 15: cingulum composed of several narrow open bands (arrows). Scale bars = 0.6 µm (Fig. 15); 0.5 µm (Figs 8–12); 0.4 µm (Fig. 14); 0.3 µm (Fig. 13).
FIGURES 16–20 in Small-sized and discoid species of the genus Cocconeiopsis (Bacillariophyta) on Holothuria atra (Juan de Nova, Mozambique Channel)
FIGURES 16–20: Cocconeiopsis juandenovensis sp. nov. (SEM) from "JDN2 Holothuria atra". Internal views. Fig. 16: Complete valve with helictoglossae (arrows). Fig. 17: Tilted apex of the valve illustrated in Fig. 16. Note virgae (short arrows), marginal rim (long arrow), and marginal row of areolae. Figs 18, 19: Note reticulate structure (short arrows) and marginal rim (long arrow). Fig. 20: Detail of edge of valvocopula, slightly undulated (short arrows). Scale bars = 2 µm (Fig. 16); 0.7 µm (Fig. 17); 0.4 µm (Figs 18–20).
FIGURES 45–47 in Small-sized and discoid species of the genus Cocconeiopsis (Bacillariophyta) on Holothuria atra (Juan de Nova, Mozambique Channel)
FIGURES 45–47: (?)Cocconeiopsis sp. (SEM) from "JDN2 Holothuria atra". Internal views. Fig. 45: Valve broken along the raphe (arrows). Fig. 46, detail of Fig. 45, marginal rim (long arrow) with fimbriate ornamentation, minute pores on a cingular band (small arrows). Fig. 47: Valve slightly asymmetrical with helictoglossae (arrows) and marginal fimbriate ornamentation. Scale bars = 4 µm (Fig. 47); 3 µm (Fig. 45); 0.5 µm (Fig. 46).
FIGURES 32–33 in Small-sized and discoid species of the genus Cocconeiopsis (Bacillariophyta) on Holothuria atra (Juan de Nova, Mozambique Channel)
FIGURES 32–33: Cocconeiopsis discoides sp. nov. (SEM) from "JDN2 Holothuria atra". Internal views. Fig. 32: detail of Fig. 33, cingulum composed of several low bands, apparently un-perforated, virgae marginally elevated and ornamented by pearls, presence of a pearl (long arrows) between each marginal areola (short arrows). Fig. 33: Complete valve with helictoglossae (arrow) and radiate striae. Scale bars = 3 µm (Fig. 33); 1 µm (Fig. 32).

FIGURES 2–7: Cocconeiopsis juandenovensis sp. nov. (SEM) from "JDN2 Holothuria atra". Figs 2–5: Fig. 5: illustration of holotype specimen). External views of valve. Figs 6, 7: details of central area. Note areolae well identifiable at the end of each stria (long arrows in Fig. 7) and difficult to observe, or absent, on stria (Fig. 7, short arrows).
