Abstract
FIGURE 2. Frontonia paramagna spec. nov. from life (A, B, F, G, I) and after staining with silver carbonate (D, E, H, J, K, M) and silver nitrate (C, L). A. Ventral view of a typical individual; arrow marks the contractile vacuole. B. Dorsal view of a typical individual. C. Arrow indicates the contractile vacuole pore. D. The postoral kineties. E. Arrows mark the somatic kineties. F-G. Photomicrographs of buccal field (arrows), showing vestibular kineties, paroral membrane and peniculi 1, 2, 3. H. To show the argentophilic line (the arrow below) and the paroral membrane (the arrow above). I, J. The spindle-shaped trichocyst. K. The macronucleus. L. Arrow indicates the peniculus 3. M. Photomicrograph of peniculi1, 2, 3 (P1, P2, P3). Scale bars in (B, C) = 200 µm; PM, paroral membrane; VK, vestibular kineties; PK, postoral kineties; Ma, macronucleus
