Abstract: Objective To provide an overview of current research on Acritochaeta Grimshaw, 1901 in China. Methods The Acritochaeta samples were collected and identified, and literature review and analysis were performed. Results Seven species of the genus Acritochaeta, including the new species of Acritochaeta qingchuanica Qian, Xie et Feng, sp. nov., are recorded in China. Of these species, 3 have the type localities in China, and all of them are endemic species in China. This paper gives a brief introduction of the identification features and ecological habits of the genus. A key and a checklist of all the known species of Acritochaeta in China are also given in this paper. Conclusion The number of species of the genus Acritochaeta is relatively small. However, as China has a vast territory and abundant natural resources, the related study should be carried on. The type specimens of new species are preserved in the Insect Museum of Institute of Plant Physiology and Ecology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai (200032), China.
