FIGURE 2 in Morphology and Molecular Phylogeny of the Soil Ciliate Cyrtohymena seorakensis sp. n. (Ciliophora, Hypotricha, Oxytrichidae)

FIGURE 2. Photomicrographs of Cyrtohymena seorakensis sp. n. from life (A–E), after protargol impregnation (F, G), and in the scanning electron microscope (H–J). A, B. Ventral and lateral view of a free swimming specimen under low magnification, showing the body outline, the distinctly convex dorsal surface (arrows in B), and the brownish color due to the crystals in the cytoplasm. C, D. Dorsal views showing the yellow, randomly scattered cortical granules (arrows). E. Optical section of a cyst showing the thin wall (opposite arrowheads) and the fused macronuclear nodules. F, G. Ventral and dorsal view of the holotype specimen showing the infraciliature and nuclear apparatus. H–J. Ventral views showing the arrangement of frontal-ventraltransverse cirri (H), the shape of the paroral membrane (arrows in H and I), and the invariably four transverse cirri (arrowheads in J). AZM—adoral zone of membranelles; BC—buccal cirrus; CC—caudal cirri; CV—contractile vacuole; DK1–6—dorsal kineties; FC—frontal cirri; LD—lipid droplets; LMR—left marginal row; MA—macronucleus; MI—micronucleus; PF—pharyngeal fibers; PM—paroral membrane; PTC—pretransverse cirri; RMR—right marginal row. Scale bars: 30 μm (A–C, F–H), 20 μm (D, I, J), 10 μm (E).
