FIGURES 6–14. Pseudourostyla cristatoides n in Morphology, morphogenesis, and molecular phylogeny of a new brackish water ciliate, Pseudourostyla cristatoides n. sp., from Songjiho lagoon on the coast of East Sea, South Korea

FIGURES 6–14. Pseudourostyla cristatoides n. sp., dividers after protargol impregnation. 6, 7. Ventral view of early dividers, the buccal cirrus (arrowheads) is dedifferentiated, arrows mark basal body patches left of some postoral midventral cirri, and proter's oral primordium (asterisk) develops from a "pocket" of buccal cavity. 8. Ventral view of late early divider, showing forming adoral membranelles, fronto-ventral-transverse cirral (asterisks) and marginal cirral anlagen (left, arrows; right, arrowheads). The posterior cirri of rear corona participate in the fronto-ventral-transverse cirral anlagen. 9–12. Ventral and dorsal views of middle dividers, the leftmost frontal cirrus develops from the anterior end of undulating membranes and migrates posteriorly (asterisks), the dorsal kineties originate by intrakinetal formation (arrows), and the micronuclei are slightly inflated. 13, 14. Ventral and dorsal view of late divider, arrows denote anteriorly migrating frontoterminal cirri. Ma, macronucleus; Mi, micronucleus. Scale bars: 100 μm.
