Coleps is a common genus of pelagic ciliates in freshwater and brackish water habitats. Classification and phylogeny of Coleps species are, however, still full of confusion. In this study, we investigated Coleps shanghaiensis n. sp., collected from a river in Shanghai, China, by living observation, protargol staining, and molecular methods. Coleps shanghaiensis is about 70-90 µm × 35-55 µm in size, has a barrel-shaped body with three posterior spines, and possesses 21-24 ciliary rows, each composed of two perioral dikinetids and 19-22 monokinetids, and six caudal cilia. In SSU rRNA gene phylogenies, C. shanghaiensis fell within the clade of subspecies of Levicoleps biwae, which questions the validity of the genus Levicoleps. Furthermore, the biogeography of the genus Coleps is discussed.
科尔普斯是淡水和半咸水生境中常见的浮游纤毛虫属。然而，科尔普斯物种的分类和系统发育仍然存在很多混乱。在这项研究中，我们通过活体观察、蛋白银染色和分子方法研究了来自中国上海一条河流的新种上海科尔普斯（Coleps shanghaiensis n. sp.）。上海科尔普斯大小约为 70-90 µm×35-55 µm，身体呈桶形，有三个后刺，拥有 21-24 排纤毛，每排由两个口围双联体和 19-22 个单体组成，还有 6 根尾毛。在 SSU rRNA 基因系统发育中，上海科尔普斯属于 Levicoleps biwae 亚种的分支，这对 Levicoleps 属的有效性提出了质疑。此外，还讨论了科尔普斯属的生物地理学。
