BLEPHARISMA UNDULANS STEIN, 1867 View in CoL
( FIGS 1G–J View Figure 1 , 4J–M View Figure 4 , 6E–K; TABLES View Figure 6 1, 4)
The morphology and infraciliature of a South Korean population of this species were recently described in detail ( Lee & Shin, 2009). Therefore, only a brief note of the Qingdao population is documented here.
Description based on Qingdao population Cells about 120–250 × 35–60 μm in vivo, body shape relatively stable: anterior conspicuously pointed, posterior end widely rounded ( Figs 1G View Figure 1 , 4J View Figure 4 ); width to thickness ratio about 2:3. Cells invariably bright pink at low magnification as a result of the presence of cortical granules. Cortical granules about 0.5 μm across, mostly dark rosered in colour although some are white (arrows in Fig. 4M View Figure 4 ), distributed in numerous longitudinal rows between kineties ( Fig. 4J, M View Figure 4 ). Pellicle soft. Peristome narrow, extending to mid-body region ( Figs 1G, I View Figure 1 , 4J, K View Figure 4 ). Paroral membrane difficult to detect in vivo ( Fig. 4J View Figure 4 ). Cytoplasm usually packed with several food vacuoles ( Fig. 4J View Figure 4 ). Two ellipsoidal macronuclear nodules, about 30 × 20 μm in stained individuals, one located in anterior and the other in posterior half of body, nuclear connective strand not detected ( Figs 1G View Figure 1 , 4K View Figure 4 ). Micronucleus not detected. Contractile vacuole c. 15 μm in diameter terminally located ( Figs 1G View Figure 1 , 4J View Figure 4 ). Locomotion mainly by gliding slowly on bottom of Petri dish.
Infraciliature consists entirely of dikinetids. Adoral zone composed of 42–68 membranelles, each of which consist of one short and two long rows of basal bodies. Paroral membrane composed of dikinetids: in anteri- or half only right basal body of each pair is ciliated, in posterior half both pairs are ciliated ( Figs 1H View Figure 1 , 4L View Figure 4 ). Twenty-one to 27 ciliary rows arranged longitudinally ( Fig. 1I, J View Figure 1 ), cilia about 10 μm long in vivo. Amongst these about nine to 12 postoral (right side) rows are shortened, i.e. only 11–16 kineties extend complete length of cell ( Fig. 1I, J View Figure 1 ).
