The genus Didymocorypha Wood-Mason, 1877 (Eremiaphilidae, Iridinae) has only been recorded in South Asia, including a sole species D. lanceolata (Fabricius). Here, we firstly extend its distribution to China, with description of one new species D. libaii sp. nov. Didymocorypha libaii sp. nov. lives in an area about 3000 meters above sea level on the southern slope of the Himalayas (Tibet in China), one of the highest-altitude inhabited areas of mantis in the Northern Hemisphere. It is also the first recorded Oriental mantis species in which both sexes are wingless. Life history of the new species, necessary illustrations and ecological images are provided. The distribution of the new Didymocorypha species is discussed and mapped.
