Morphology of Thigmokeronopsis stoecki based on present population ( Figs 1–7 View Figs 1–7 , Table 1)

Body size in vivo about 140–230 × 70–80 µm; cell highly contractile and shape variable, generally elongated fusiform with anterior slightly narrow and round- ed, and posterior tapered ( Figs 1, 4, 5 View Figs 1–7 ). Cell brownish to dark brown in color. Adoral zone about 40% of cell length. Pellicle flexible and thin, with brightly grassgreen cortical granules (about 2 µm long, red blood cell-shaped) sparsely distributed beneath ( Figs 6, 7 View Figs 1–7 ). Cytoplasm colorless, filled with many tiny lipid droplets. More than 100 macronuclear nodules. Contractile vacuole positioned in anterior two-fifths on left side of cell.

Adoral zone composed of 70–83 membranelles, with its distal end curving strongly posteriad along the right cell margin and extending to about cytostome level. Fifteen to 26 frontal cirri, which are not clearly distinguished from the midventral cirri posteriorly, forming typical curved bicorona. Two frontoterminal, one buccal and five to eight transverse cirri. Midventral complex comprising a total of 32–40 pairs of cirri that are distinctly separated and thus are not arranged in a typical zig-zag pattern, terminating near the transverse cirri. Left and right marginal row with 46–65 and 47–55 cirri respectively, nearly confluent posteriorly. Thigmotactic field (TF) dominant, consisting of 11–15 densely arranged, longitudinal rows of cirri. Three complete dorsal kineties ( Figs 2, 3 View Figs 1–7 ).
