FIGURE 3. Frontonia lynni n. sp. live (A–D), after protargol (J), silver carbonate (F, G, H, K) and silver nitrate impregnation (E, I). (A) Dorsal view. (B) Arrangements of extrusomes and cilia. (C) Buccal area, showing vestibular kineties (arrowhead) and extrusomes (arrow). (D) Dorsal view, showing the contractile vacuole. (E) Buccal area, arrowheads refer to peniculi, arrow marks argentophilic line. (F) Lateral view, showing anterior suture (arrowhead). (G) Lateral view, showing posterior suture (arrow). (H) Infraciliature of oral field, arrow marks postoral kineties, arrowheads indicate vestibular kineties. (I) Silverline system. (J) Lateral view, arrowheads mark ingested diatoms. (K) A part of pellicle, arrowhead refers to a single kinetosome, arrow shows a rest extrusome. Scale bars = 50 µm.
