Jiangsu Province is located on the southeast coast of China and lacks high-altitude mountains, with only a few hilly areas mainly distributed in its southern region. In recent years, We investigated the diversity of Plecoptera species in the major mountainous and forested areas of Jiangsu, recording a total of 20 species across 12 genera and five families. In this paper, we examined the materials of Kamimuria from Jiangsu and described a new species, K. liyangensis sp. nov. In addition, detailed English descriptions and colour pictures of K. microda are provided for the first time.
