摘要海洋缘毛纤毛虫一新种，中华拟涡壳虫Pseudovorticella sinensis n.从青岛市沿岸的对虾养殖池中分离到一株中国对虾新单胞菌。根据活体标本和浸银标本，研究了其形态、纤毛下结构和银线系统。该物种的特征是：（1）一个细长的钟形体，在体内测量为50-60 × 35-45 μm，（2）一个大的，位于腹侧的收缩液泡，（3）一个被一层透明的皮层小泡覆盖的表膜。从口缘区到离口纤毛环的横银线数目为26-32条，从离口纤毛环到气管的横银线数目为12-15条。茎长约160-250 μm，宽约5-6 μm。刺丝体有一排明显的壁质颗粒，直径约0.8 μm。
Abstract A new marine peritrich ciliate, Pseudovorticella sinensis n. sp. was isolated from a shrimp-farming pond in the littoral area of Qingdao, China. The morphology, infraciliature, and silverline system were studied based on living and silver-impregnated specimens. This species is characterized by (1) an elongated bell-shaped body that measures 50–60 × 35–45 μm in vivo, (2) one large, ventrally located contractile vacuole, and (3) a pellicle covered by a layer of transparent, cortical vesicles. The number of transverse silverlines from the peristomial area to the aboral ciliary wreath is 26–32, and from the aboral ciliary wreath to the scopula is 12–15. The stalk measures about 160–250 μm long × 5–6 μm wide. The spasmoneme has one row of conspicuous thecoplasmic granules, which are about 0.8 μm in diameter.
