08E20446E18D51DA86BE6E34B0BEECDF.taxon	description	Description. Size 70 – 90 × 20 – 30 μm in vivo, and 39 – 54 × 16 – 25 μm (average 49 × 19 μm) in protargol preparations; length: width ratio about 2.5: 1 (Table 1). Outline slightly ovate or elliptical, with both ends rounded (Figs 1 A – F, I, J, 2 A, B). Two globular to ellipsoidal macronuclear nodules, anterior nodule about 8 × 5 μm and posterior nodule about 9 × 5 μm in protargol preparations; one micronuclei, about 3 μm in diameter in protargol preparations, located between macronuclear nodules (Fig. 1 C, G, I). Contractile vacuole slightly anterior to mid-body near left margin of the cell, approximately 10 μm in diameter when fully extended (Fig. 1 A, D, E). Cytoplasm colorless, with lipid globules, many irregular crystals and food vacuoles. Adoral zone occupies about 40 % of body length and is composed of 17 – 24 membranelles, with cilia about 13 μm long (Fig. 1 A, B, I; Table 1). Paroral and endoral membrane slightly bent and arranged in parallel (Fig. 1 B, I). All cirri with cilia 8 – 15 μm long in vivo (Figs 1 A, 2 C). Eighteen frontoventral-transverse cirri: three frontal cirri close to the adoral zone of membranelles (Fig. 1 A, B); buccal cirrus near the anterior end of undulating membranes. Three enlarged frontal cirri near the distal portion of the adoral zone, four frontoventral cirri, buccal cirrus near the anterior end of undulating membranes, and three postoral ventral cirri located in the central body, and two pretransverse cirri (Fig. 1 B, I; Table 1). Five rod-shaped transverse cirri, about 25 μm long arranged in a V shape, each with a fringed distal end (Fig. 1 B, H, I; Table 1). One left (10 – 13 cirri) and right (9 – 13 cirri) marginal row, both marginal rows non-confluent posteriorly (Fig. 1 B, I; Table 1). Four dorsal and three dorsomarginal kineties with conspicuously long dorsal cilia 10 – 15 μm long. Dorsomarginal kinety 5 starts near the anterior end of the cell and extends to 2 / 3 of the body. Three caudal cirri located at the ends of dorsal kineties 1, 2, and 4 on the posterior end of the cell (Fig. 1 C, J).	en	Chae, Kyu-Seok, Min, Gi-Sik, Park, Kyung-Min (2025): Morphology and molecular phylogeny of Monomicrocaryon trimarginalis sp. nov.
