Figure 14. Photomicrographs of (A–I) Strombidium apolatum nov. spec. and (J–N) Heterostentor shenae after protargol impregnation. (A) Dorsal view, to show the gap between the equatorial and ventral kinety (arrow); (B) dorsal view, black arrow marks the macronucleus, whereas the white one indicates the end of ventral kinety; (C) ventral view, white and black arrows point to the kinety-gap and macronucleus, respectively; (D, H) macronucleus; (E) dorsal view, to show the equatorial kinety and the girdle (arrows); (F) ventral view, arrowheads mark the inconspicuous buccal membranelles, whereas the arrow points to the cytopharynx; (G) ventral view, focusing at surface level, arrow indicates the newly formed oral primordium, arrowheads mark the equatorial kinety; (I) ventral view, to show the girdle (black arrows) and the equatorial kinety (white arrows); (J) dorsal side of anterior portion, to show the adoral zone of membranelles; (K, M) ventral view, arrow indicates the proximal end of adoral zone of membranelles, while the arrowheads in (K) mark the suture, where some kineties are shortened; (L) to show some irregularly arranged membranelles (arrows); (N) caudal view, to show the thigmotactic area, where the basal bodies are densely arranged (arrows).
