Fig. 7. Rebecca billardiae Véron sp. nov. (AC537), flagellate motile and non-motile cells, LM images. A. Gathering angular non-swimming flagellate cells with an S-shaped AF (white arrows). B. Polyhedral free-swimming cell with bilobed lateral golden-brown C, S-shaped AF (white arrow) and posterior beaded filipodium (black arrows). C–D. Cells of various shapes showing sub-apical insertion into a pit (white arrows) of the S-shaped AF. Posterior branched beaded filipodia present at the terminal part of the cell (black arrows). E. Ventral view of an angular free-swimming cell with sub-apical insertion of S-shaped AF into a pit (white arrow). F.
