Fig. 3

Photomicrographs of Gruberia foissneri spec. nov. from life (ag, iq) and after Hoechst 33342 staining (h). a–g, General right-lateral views to show the different body shapes and ratios of buccal length to body length, arrows mark the cytopharynx, arrowheads indicate the macronucleus. h, Hoechst 33342-stained individual, to show the macronucleus. i, Right lateral view of anterior end of cell, arrow marks the rostral apex. j, Cytoplasm filled with many empty vacuoles. k, Details of adoral zone, arrows mark the conspicuous cilia of the paroral membrane, arrowheads indicate the adoral zone of membranelles. l, Cortical granules (arrows) arranged in 3–5 irregular lines between adjacent somatic kineties. m, Tangential section of the cell to show the thick cortex, arrows mark the rod-shaped cortical granules. n, Rod-shaped mitochondria (?) (arrows) under the cortex. o–q, Various macronucleus shapes (arrows), arrowheads indicate the contracted region. Abbreviation: Ma, macronucleus. Scale bars = 150 μm (ad), 100 μm (e, f), 75 μm (g, h), 20 μm (iq)
