摘要：
A new marine peritrich ciliate, Pseudovorticella paracratera n. sp., was isolated from marine waters off the coast of Qingdao, China. The morphology, infraciliature, and silverline system were studied from living and silver-impregnated specimens. It is characterized by a wide conical or inverted bell-shaped body which measures 40–88 μm in length × 64–144 μm in width in vivo, two ventrally located contractile vacuoles, and a wide peristomial lip with closely-spaced, irregular tubercles. The pellicle is tubercular with conspicuous, widely-spaced striations. There are 15–18 transverse silverlines between the peristomial lip and the aboral ciliary wreath and 9–11 between the aboral ciliary wreath and the scopula. The stalk is 8–10 μm wide and about 5–12 times the zooid length. The spasmoneme has numerous conspicuous thecoplasmic granules.
