Figure 2. Photomicrographs of Sterkiella paratricirrata n. sp. from life (a–h) and after staining with protargol (i–l). (a–d) Ventral views, showing the different body shapes, arrow in (a) marks the contractile vacuole. (e) Ventral view of the posterior portion of a cell, showing transverse cirri. (f) Showing nuclear apparatus. (g, h) Resting cyst, showing the cyst wall (opposed arrowheads in g). Squeezed cyst (h) with cytoplasm released, showing the polygon wrinkles on the surface. (i) Ventral view of the buccal field. (j) Dorsal view shows three caudal cirri (arrow). (k, l) Ventral (k) and dorsal (l) view of the holotype specimen, showing the general cirral pattern, arrowheads in (k) mark the dorsal kineties. Ma, macronuclear nodules; P, paroral; PTVC, pretransverse ventral cirri; PVC, postoral ventral cirri. Scale bars = 15 µm (g, h) and 50 µm (a–d, k, l).
