Ciliates are core components of the structure of and function of aquatic microbial food webs. They play an essential role in the energy flow and material circulation within aquatic ecosystems. However, studies on the taxonomy and biodiversity of freshwater ciliates, especially those in wetlands in China are limited. To address this issue, a project to investigate the freshwater ciliates of the Lake Weishan Wetland, Shandong Province, commenced in 2019. Here, we summarize our findings to date on the diversity of ciliates. A total of 187 ciliate species have been found, 94 of which are identified to species-level, 87 to genus-level, and six to family-level. These species show a high morphological diversity and represent five classes, i.e., Heterotrichea, Litostomatea, Prostomatea, Oligohymenophorea, and Spirotrichea. The largest number of species documented are oligohymenophoreans. A comprehensive database of these ciliates, including morphological data, gene sequences, microscope slide specimens and a DNA bank, has been established. In the present study, we provide an annotated checklist of retrieved ciliates as well as information on the sequences of published species. Most of these species are recorded in China for the first time and more than 20% are tentatively identified as new to science. Additionally, an investigation of environmental DNA revealed that the ciliate species diversity in Lake Weishan Wetland is higher than previously supposed.

纤毛虫是水生微生物食物网结构和功能的核心组成部分。它们在水生生态系统的能量流动和物质循环中起着至关重要的作用。然而，关于淡水纤毛虫的分类学和生物多样性的研究，特别是中国湿地的淡水纤毛虫研究有限。为了解决这个问题，一项调查山东省微山湖湿地淡水纤毛虫的项目于2019年启动。在此，我们总结了迄今为止关于纤毛虫多样性的研究结果。共发现187种纤毛虫，其中94种已鉴定到种级，87种鉴定到属级，6种鉴定到科级。这些物种表现出高度的形态多样性，分属于五个纲，即异毛纲、膜口纲、前口纲、寡膜纲和旋毛纲。记录的物种数量最多的是寡膜纲。已经建立了一个关于这些纤毛虫的综合数据库，包括形态学数据、基因序列、显微镜载玻片标本和一个DNA库。在本研究中，我们提供了检索到的纤毛虫的注释清单以及已发表物种的序列信息。这些物种大多数是首次在中国被记录，超过20%被初步鉴定为科学新物种。此外，对环境DNA的调查显示，微山湖湿地的纤毛虫物种多样性比以前认为的要高。
