Figure 4 in Re-evaluation of the systematic position of the order Prostomatida (Protista: Ciliophora), with the establishment of two new genera and two new species

Figure 4. Drawing (A–E) and photomicrographs (F–L) of Parametacystis pulchra gen. nov., sp. nov. from life (A, D, F–H) and after protargol staining (B, C, E, I–L). A, lateral view of a representative individual, showing general appearance of body and protruding caudal vacuole (arrow). B, C, side view of the holotype specimen, showing ciliary pattern of the cell and circumoral kinety (arrowheads). D, showing the pattern of the silverline system and cortical granules. E, ciliary pattern of the anterior portion of the cell, showing the circumoral kinety (CK) and the perioral kineties (PK). F, showing the protruding caudal vacuole (arrow). G, lateral view of a slightly contracted individual, showing the furrows in ectoplasm (arrowheads). H, compressed individual, showing the pattern of the silverline system and cortical granules (arrows). I, lateral view of holotype specimen, showing ciliary pattern and macronucleus (Ma). J, showing the macronucleus and micronucleus (arrow). K, L, showing the circumoral kinety (arrowheads) and perioral kineties (arrows). Scale bars: 20 μm.
