FIGURE 2. Photomicrograph of Urosomoida sejongensis n. sp. in vivo (A–J) and after protargol impregnation (K, L). A, B. Ventral and dorsal view. Arrow denotes contractile vacuole. C, D. Lateral views. E. Dorsal view showing contractile vacuole (arrow) with dorsal bristles (DB). F. Ventral view with overall cirral arrangement. G. Ventral view with nuclear apparatus and ring-shaped structures (inserts). H. Ventral view of oral apparatus. I. Nuclear apparatus showing 1 micronucleus between 2 macronuclear nodules. J. Cortical granules (arrowhead). K, L. Dorsal and ventral view of holotype specimen, respectively. AZM—adoral zone of membranelles; BC—buccal cirrus; CC—caudal cirri; DK—dorsal kineties; DM—dorsomarginal kinety; FC—frontal cirri; FVC—frontoventral cirri; LMR—left marginal cirral row; Ma—macronuclear nodules; Mi—micronucleus; PTVC—pretransverse ventral cirri; PVC—postoral ventral cirri; RMR—right marginal cirral row; TC—transverse cirri. Scale bars: 50 µm (in A, E, K), 5 µm (in I, J).
