A–O Morphology of Heterodeviata nantongensis nov. sp. from life (A–G) and after protargol staining (H–O). A–C Ventral view of a representative individual, arrow in (A) indicates the contractile vacuole and arrow in (C) showing buccal lip. D, E Detail of the anterior end of body, arrow in (D) indicates pharyngeal fibers and arrows in (E) indicate frontal cirri. F Showing the cytoplasm and macronuclear nodules. G Showing granular inclusions and marginal cirri. H, I Ventral (H) and dorsal (I) views of the holotype, denoting infraciliature and nuclear apparatus, arrows show the two dorsal bristles of dorsal kinety 2 and arrowheads denote the caudal cirri. J Dorsal view of the anterior portion of cell, showing the left dorsal kinety and dorsomarginal kinety composed of two dikinetids (arrows). K Details of the oral zone, arrow indicates the parabuccal cirrus and arrowhead marks the buccal cirrus. L Showing the nuclear apparatus, arrows indicate micronuclei. M Details of paroral membrane and endoral membrane. N Arrowhead indicates anterior segment of frontoventral row and arrow indicates posterior segment in a daughter cell just after division. O Showing three caudal cirri behind the dorsal kinety 1, arrows indicate the caudal cirri. DK1, dorsal kinety 1; EM, endoral membrane; FC, frontal cirri; FVR, frontoventral cirral row; LMR1, 2, 3, left marginal row 1, 2, 3; Ma, macronuclear nodules; Mi, micronuclei; PM, paroral membrane; RMR1, 2, right marginal row 1, 2; Scale bars = 60 μm
