摘要：
Three new Chinese species of the genus Mesonemoura (Plecoptera: Nemouridae), Mesonemoura dilatata Du & Ji, sp. nov., M. sichuanensis Du & Ji, sp. nov. and M. sinistracurva Du & Wang, sp. nov., are described and illustrated. Mesonemoura dilatata is characterized by the flagellum of the epiproct being long and curved, forming a swollen membranous apex. Mesonemoura sichuanensis is characterized by tergum 9 forming a pair of obtuse angles mid-posteriorly, and by the ventral sclerite of the epiproct being basally broad, 2 x the width of the dorsal sclerite. Mesonemoura sinistracurva is characterized by the presence of a long stylus that curves abruptly to the left as it leaves the tip of the epiproct. A key to the Chinese species of this genus is presented.
