Figure 9. Thigmokeronopsis magna nov. spec. from life (A, B, H–J) and after protargol impregnation (C–G, K). (A) A typical specimen, ventral view; (B) schematic, to show the pattern of movement when swimming; (C) four pairs of midventral cirri, to demonstrate the fibre system associated with the cirri; (D) details, to show transverse (arrow) and thigmotactic cirri (arrowhead); (E) ventral view, arrows mark the thigmotactic area; (F) dorsal view of the same cell as in (E), to show the distribution of macronuclei, arrows mark the dorsal kineties; (G) several macronuclear nodules; (H) two different body forms, arrow points to the contractile vacuole; (I) diagram showing the pattern of movement while on the bottom; (J) the third type of movement: cells firmly attached to the bottom, arrows mark the thigmotactic area; (K) anterior portion of ventral side, arrowhead marks the paroral membrane, double-arrowheads indicate the endoral membrane, arrow points to the frontoterminal cirri. Scale bars: 100 Mm (A); 50 Mm (E, F); 150 Mm (H); 40 Mm (K). : Published as part of Wilbert, Norbert & Song, Weibo, 2005, New contributions to the marine benthic ciliates from the Antarctic area, including description of seven new species (Protozoa, Ciliophora), pp. 935-973 in Journal of Natural History 39 (13) on page 957, DOI: 10.1080/00222930400001509, http://zenodo.org/record/4657793
