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).
