Fig. 4

Photomicrographs of Gruberia foissneri spec. nov. after protargol staining. a, Right-lateral view of a typical specimen. b, Detail of oral apparatus, arrows mark the paroral membrane, arrowheads show the adoral zone of membranelles, double arrowheads indicate the cytopharynx. c, Enlargement of the anterior part of paroral membrane, arrows indicate the fragments consisting of three lines of kinetosomes, arrowheads mark the fragments consisting of two lines of kinetosomes. d, Enlargement of the posterior portion of paroral membrane, arrows mark fragments composed of two rows of kinetosomes, arrowheads indicate the proximal region of the paroral membrane that is not fragmented. e, Ventral view of the adoral zone of membranelles (arrowheads) and paroral membrane (arrows). f, Ventral view of the ciliary pattern, arrows mark the shortened kineties originating from left margin of adoral zone of membranelles or oral cavity, arrowheads mark the shortened kineties interspersed among bipolar kineties. g, Detail of dikinetids, arrows mark ciliated basal body. h, Macronucleus. i, Ventral view of posterior portion adjusted by the invertible function in Photoshop, asterisks mark a conspicuous suture. Abbreviation: Ma, macronucleus. Scale bars = 100 μm (a), 50 μm (b, i), 30 μm (ch)
