Figs 5A–N in Morphology of Two Novel Species of Chaenea (Ciliophora, Litostomatea): Chaenea paucistriata spec. nov. and C. sinica spec. nov.

Figs 5A–N. Chaenea sinica spec. nov. in vivo (A–G) and after protargol impregnation (H–N). A, B – typical individuals; C–E – contracted and twisted cells; F, G – rod-shaped extrusomes attached to oral bulge (F) and scattered in cytoplasm (G); H–J – ciliary pattern of anterior body end, showing circumoral kinety, dorsal brush rows 1–4, and nematodesmata; K – middle part of body, showing somatic kineties; L – anterior body end, arrowheads denote the extruded extrusomes outside the oral bulge; M – anterior body end, arrowhead marks cilia of the dorsal brush; N – many scattered macronuclear nodules throughout cytoplasm (arrowheads). B1–4 – dorsal brush rows 1–4, CK – circumoral kinety, CV – contractile vacuole, E – extrusome, N – nematodesmata, SK – somatic kinety. Scales bars: 100 µm.
