Fig. 4A–K in Morphology and Ontogenesis of a Marine Ciliate, Euplotes balteatus (Dujardin, 1841) Kahl, 1932 (Ciliophora, Euplotida) and Definition of Euplotes wilberti nov. spec.

Fig. 4A–K. Euplotes balteatus and Euplotes wilberti nov. spec. from life (A, G), after protargol (D, J, K) and silver nitrate (B, C, E, F, H, I) impregnation. Arrows point to the marginal cirri. A – ventral view of Euplotes balteatus, to show the ventral ciliature (from Kahl 1932); B, C – ventral and dorsal views of Euplotes balteatus, showing the silverline systerm (from Tuffrau 1964); D – Euplotes balteatus, to show variations in the shape of the macronucleus; E, F – ventral and dorsal views showing the silverline system; G–K – Euplotes wilberti nov. spec., to show the live morphology (G), silverline system (H, I), infraciliature (J, K) and macronucleus (K) (from Song and Wilbert 2002). Scale bar: 30 µm.
