Figure 15. Clevelandella sidi sp.nov.in vivo (A, B) and after protargol impregnation (C–H). From SRU (A–H). A, ventral view showing contractile vacuole (white arrowhead) and cilia of adoral membranelles (white arrow). B, ventral view showing contractile vacuole (white arrowhead), adoral membranelles (black arrow), and elevated margin of the cytoproct (white arrow).C–E, the same cell in dorsal view: C, showing somatic infraciliature (asterisk), cytoproct (black arrowhead), and adoral membranelles (white arrow); D, showing cytoproct (black arrowhead) and dorsal kineties (white arrowhead); E, optical section showing excretory antrum within the left protuberance (black arrowheads). F, detail of the macronucleus showing the karyophore (white arrow). G, detail showing the micronucleus (white arrowhead). H, detail of the paroral membrane showing both files of equal length and extending nearly to the posterior end of the peristomial projection (white arrowheads), a feature unique to this species.Asterisk marks the anterior end. Ma, macronucleus.Scale bars:20 µm (A–D) 10 µm (E–G), 5 µm (H, I).
