本文研究了从青岛、中国等地分离到的三种海洋纤毛虫的生活形态和纤毛。与其同源种中华直生辣椒Orthotrochiia Sinica Spec.11月体形细长椭圆形，体内大小约50-60×20-25μm，体细胞运动18-21个，左侧口周运动长度是右侧运动长度的三倍，右侧有两个腹侧可收缩的空泡，有25-32个线虫间连丝。根据目前的观察和前人的描述，对细小轮虫的诊断(Deroux，1976)Chen等人进行了讨论。2011年得到改进：体内细胞大小为30-40×20-35μm，轮廓呈椭圆形；一致的三个右运动，四个左运动和七个后运动；一个可收缩的液泡；海洋生物栖息地。T.recta(Kahl，1923)Chen et al.2011年是基于一个中国人的流行而重新描述的。此外，还提供了一种可供参考的分类检索表和Chlamydonyx trivialis(Fichel，1965)Comb.11月(basionym：Trochiioidestrivialesenchel，1965)。
The present work investigates the living morphology and infraciliature of three marine cyrtophorid ciliates, which were isolated from Qingdao, China. Compared with its congeners, Orthotrochilia sinica spec. nov. can be distinguished by a combination of features: body slender and elliptical in outline, size about 50-60 × 20-25 μm in vivo, 18-21 somatic kineties, the length of the left perioral kinety tre- ble the length of the right one, two ventrally located contractile vacuoles on the right side, and 25-32 nematodesmal rods. Based on current observations and the previous description, the diagnosis of Trochilioides tenuis (Deroux, 1976) Chen et al. 2011 is improved: cell size 30-40 × 20-35 μm in vivo, oval shaped in outline; consistently three right kineties, four left kineties and seven postoral kineties; a single contractile vacuole; marine habitat. A second species of Trochilioides, T. recta (Kahl, 1923) Chen et al. 2011 is re-described based on a Chinese popu- lation. Furthermore, a key to the identifi cation of species of the genus Trochilioides whose infraciliature data are available is supplied, and Chlamydonyx trivialis (Fenchel, 1965) comb. nov. (basionym: Trochilioides trivialis Fenchel, 1965) is suggested.
