Fig. 3 in Morphology of Three Aloricate Choreotrich ciliates, Including Description of a New Species Parastrombidinopsis costalis sp. n. (Ciliophora, Choreotrichia), and phylogeny of the genus Parastrombidinopsis

Fig. 3. Photomicrographs of Parastrombidinopsis costalis sp. n. from life (A–F, J) and after protargol staining (G–I, K–N), (A–E, G–J, L, M) from Zhuhai population, and (F, K, N) from Sanya population. (A–C) Ventral-left, ventral, left-lateral views of one individual, arrows mark the dorsal ridge. (D, E) Ventral-left, ventral-right views of one individual; arrows mark the dorsal ridge. (F) Ventral-right view of one individual, arrow marks the dorsal ridge. (G, H) Ventral and dorsal views of one specimen, showing the somatic ciliature. (I) Ventral view of oral ciliature; arrow marks buccal membranelle. (J) Bases of oral membranelles; arrow marks buccal membranelle. (L) An early divider; arrow marks the oral primordium. (M) Two macronuclei. (K, N) Ventral and dorsal views of one specimen, showing the somatic ciliature. CM, collar membranelles; Ma, macronucleus; SK, somatic kinety. Scale bars: 25 μm (A, D); 20 μm (F); 3 μm (J).
