Figures

Fig. 1A–J. Morphology of Pinacocoleps pulcher (Spiegel, 1926) in vivo (A–C), protargol impregnation (D–G), previous studies (H, I), and closely related congeners (J, K). A. Broad side lateral view of a typical individual. B. Detailed structure of one row of armor plates (arrowhead denotes plate tooth). C. Slender side lateral view. D. Ciliary pattern (apical view). E. Schematic drawing of detailed somatic ciliature and silverlines (arrow indicates parasomal sac and arrowhead indicates basal body of somatic kinetid). F. Ciliary pattern (caudal view). G. Somatic ciliary rows. H, I. P. pulcher (H from Spiegel 1926; I from Kahl 1930). J. P. heteracanthus (from Noland 1937). K. P. arenarius (from Bock, 1952). AO – adoral organelles, AS – anterior spines, CC – caudal cilium, CK – circumoral kineties, COP – circumoral plate, CP – caudal plate, CV – contractile vacuole, TP – tiny pore, Ma – macronucleus, Mi – micronucleus, PC – perioral ciliature, PS – posterior spines, SK – somatic kineties. Scale bars: 30 μm (A, G–K).
