FIGURE 3 in Morphology and Molecular Phylogeny of the Soil Ciliate Cyrtohymena seorakensis sp. n. (Ciliophora, Hypotricha, Oxytrichidae)

FIGURE 3. Line drawings of protargol-impregnated dividing specimens of Cyrtohymena seorakensis sp. n. Parental cirri and dorsal bristles drawn as outlines, newly formed structure are in black. A, B. Ventral and dorsal view of a mid-divider specimen, showing the frontal-ventral-transverse anlagen (arrows), the undulating membranes anlagen (arrowheads), and the dorsal kineties 1–3 anlagen. Note the fusion of the macronuclear nodules. C, D. Ventral and dorsal view of late divider, showing the frontal-ventral-transverse cirri migrate to their original locations, the dorsomarginal kineties (kineties 5 and 6) anlagen originate very close to the right marginal cirral row, and the new caudal cirri. Note the opisthe has 14 frontal-ventral-transverse cirri differing from all other cells in the preparations (~50 non-dividing cells). E, F. Ventral and dorsal view of very late divider, showing the frontal-ventral-transverse cirri already in their specific locations, the fragmentation of kinety 3 producing kinety 4 (arrows) posteriorly. CC—caudal cirri; DK1–6—dorsal kineties; DM—dorsomarginal kineties; LMR—left marginal row; MA—macronucleus; MI—micronucleus; OP—oral primordium; RMR—right marginal row; TC—transverse cirri. Scale bars: 30 μm.
