Fig. 1–8 in New Paramecium (Ciliophora, Oligohymenophorea) congeners shape our view on its biodiversity

Fig. 1–8 General shape and cortex construction of P. boetschlii sp. nov. 1–2 Ventral 1 and dorsal 2 views of the same cell. Ampoules of contractile vacuoles (CV) and its pores (wedge-tailed arrows in Fig. 2) as well as the macronucleus (MA) and the micronucleus (large arrow in Fig. 1) are visible. 3 Deciliated cell (found by chance) from the ventral view. Position of oral aperture (OA), anterial suture (arrowhead) and cytoproct (C) are shown. 4–8 Impregnated cells: ventral 4 and dorsal 5 side of different cells and its details; quadrulus (Q), cytoproct (C) and pores of contractile vacuole (PCV). 6 Buccal overture with buccal ciliature: endoral membrane (EM) and quadrulus (Q). 7 Two pores of the same contractile vacuole. 8 Cytoproct region. 1–3 Living cells, DIC contrast. 4–8 Silver nitrate impregnation. Bars 50 μm (1–3), 25 μm (4, 5), 10 μm (6, 8), 5 μm (7)
