Abstract: The species of the Stenus aureolus group occurring in China are revised. Ten species are recognized, of which six are described as new: S. mendaensis sp. nov. from Qinghai, S. aduncus sp. nov. from Sichuan, S. platydentatus sp. nov., S. tenuidentatus sp. nov., S. paratrigonuroides sp. nov., and S. alpigenus sp. nov. from Yunnan. Stenus ambiseminiger Zhao & Zhou, 2006 is transferred from the synonymy with S. trigonuroides Zheng, 1993 to the synonymy with S. aureolus Fauvel, 1875. Stenus aureolus is newly recorded from China (Heilongjiang, Jilin, Neimenggu). New province records are reported for S. trigonuroides (Sichuan, Ningxia, Shaanxi, Qinghai, Gansu). Habitus and diagnostic characters of all species are photographed. A key to Chinese species of the group is provided.
