Fig. 1A–P in Morphology and Ontogenesis of a Marine Ciliate, Euplotes balteatus (Dujardin, 1841) Kahl, 1932 (Ciliophora, Euplotida) and Definition of Euplotes wilberti nov. spec.

Fig. 1A–P. Euplotes balteatus from life (A–G, L–N), after protargol (J, K, O, P) and silver nitrate (H, I) impregnation. A – ventral view of a typical individual; B – ventral view of a well-fed specimen; C – dorsal views showing general body shape; D – ventral view to demonstrate the arrangement of cirri; E, F – details of cell (ventral view), arrow and arrowhead in E indicate the left marginal cirri and paroral membrane respectively; arrows in F mark the dorsal cilia; G – arrows denote the transverse cirri; H, I – silverline system on dorsal and ventral sides respectively; J – macronucleus (arrows); K – infraciliature on ventral side; L – ventral view of a representative individual, arrow indicates the contractile vacuole; M – sub-pellicular rod-like structures around dorsal cilia; N – lateral view, to show the flattened body shape; O, P – ventral and dorsal views, to show the infraciliature and nuclear apparatus. CC – caudal cirri, LMC – left marginal cirri, Ma – macronucleus, Mi – micronucleus, PM – paroral membrane. Scale bar: 40 µm.
