[Display omitted] •The description of one new species of Pteronemobius.•The description of two new species of Metiochodes.•Distributions of Pteronemobius and Metiochodes in China. The article describes three new species of Nemobiinae Saussure, 1877 and Trigonidiinae Saussure, 1874 from Yunnan Province, namely Pteronemobius (Stilbonemobius) alboguttatus Ma & Tao sp. nov., Metiochodes wanzhii Ma & Tao sp. nov. and Metiochodes polycomus Ma & Tao sp. nov.. Among them, P. (S.) alboguttatussp. nov. has a short, rounded shield on the ectoparamere, four internal dorsal spurs on the hind tibia, and many white spots on the head, other morphological characteristics are similar to Pteronemobius (Stilbonemobius) longispinus Gorochov, 1984. Furturemore, M. wanzhiisp. nov. and M. polycomussp. nov. can be distinguished by the number of main veins in the forewing and the shape of the epiphallus and ectoparamere. Here, we provide a detailed description and photos of the new species. LSIDurn:lsid:zoobank.org:pub:099A8DC4-0D79-4390-AC28-44E14899EFD8.
