Scanning electron micrographs (SEM) of Auranticordis quadriverberis n. gen. et sp. A. An anterior view of the cell showing the anterior apex (arrowhead), ventral groove (double arrowhead) and flagella (arrow) (Bar = 10 μm). B. A higher magnification view of the anterior end of the cell (arrowhead) showing the flagella (arrow) within the ventral groove (double arrowhead) (Bar = 2 μm). C. High magnification view of the ridges showing several tiny pores (arrowheads) in the grooves (Bar = 1 μm). D. High magnification view of secreted mucus (arrowheads) (Bar = 0.5 μm). E. High magnification view of the ventral groove showing all four flagella (arrows) bundled together and covered in hairs (Bar = 0.5 μm).
