Schematic drawings of Gruberia foissneri spec. nov. from life (a, b, d, f, g) and after protargol staining (c, e, h, i). a, Right-lateral view of a typical individual. b, Various individuals to show different body shapes and ratios of buccal length to body length. c, Pattern of the adoral zone of membranelles (red) and paroral membrane (green), arrows show fragments with three rows of kinetosomes. d, Cortical granules distributed between the ciliary rows. e, Various macronuclear shapes, arrows mark the contracted regions. f, Schematic drawing of a tangential section of the cortex, arrow marks the cortical granules, arrowhead indicates the rod-shaped mitochondria (?). g, Rod-shaped mitochondria (?) regularly arranged underneath cortex, arrowheads indicate the position of somatic kineties. h, Schematic drawing of the adoral membranelles and paroral membrane, green indicates adoral membranelles that enter the oral opening, arrows mark the anterior fragments consisting of two or three rows of kinetosomes, arrowheads show the shortened somatic kineties along the left margin of the adoral zone of membranelles. i, Ventral view to show the infraciliature and sausage-shaped macronucleus. Scale bars = 135 μm (a), 110 μm (i)
