Fig. 3. A–F in Morphology and Morphogenesis of a Chinese Population of the Soil Urostylid Ciliate, Extraholosticha sylvatica (Foissner, 1982) Li et al., 2017 (Ciliophora, Hypotrichia)

Fig. 3. A–F Morphogenesis of Extraholosticha sylvatica after protargol staining. (A, B) Ventral (A) and dorsal (B) view of a late divider. Arrowheads mark the dorsal kineties anlagen. (C, D) Ventral and dorsal view of a late divider. Note that two frontoterminal cirri (arrows in C), the pretransverse cirri (arrowheads in C), transverse cirri (double-arrowheads) and dorsal kineties anlagen (arrowheads in D) are formed in both the proter and the opisthe, as well as caudal cirri derived from the posterior end of dorsal kinety anlage 5 in both daughter cells (arrows in D). (E, F) Ventral (E) and dorsal (F) view of the same late specimen, to demonstrate that almost all the cirri have arrived their final place. Arrows denote the caudal cirri formed from dorsal kinety anlage 5 and arrowheads mark the dorsal kineties anlagen. DKA, dorsal kineties anlagen; LMA, left marginal anlagen; Ma, macronuclear nodules; Mi, micronuclei; RMA, right marginal anlagen. Scale bars = 75 μm (A–F).
