Abstract
This contribution to the taxonomy of Xya Latreille, 1809 (Orthoptera, Tridactyloidea, Tridactylidae) adds descriptions and photographic illustrations of two new species: Xya xishangbanna sp. nov. and Xya yunnanensis sp. nov. from Xishuangbanna, Yunnan Province, China. Xya xishangbanna sp. nov. can be diagnosed by the shiny dark brown hind femora, and the epiproct with a shallow bottom of the middle “v-shaped” crack in the upper part and straight sides; Xya yunnanensis sp. nov. can be diagnosed by the compound eye bearing no narrow band along the inner margin, and the epiproct with the bottom of the side edge with a sharply angled protrusion and a narrow lower anchor-shaped base less than 1/2 the width of the upper one. Distributional information and bionomics for these two new species and photos for the habitat are given. A key to all Chinese species of Xya is provided.
