A new species Xya leshanensis sp. nov. of the genus Xya Latreille, 1809 from Sichuan, China is described in this paper. It is similar to Xya nitobei (Shiraki, 1913), but differs from latter by apical part of antennae joint almost as same as basal part in width; width of pronotum 1.25 times its length; hind wing long, extending over the end of abdomen distinctly; hind femur with four small yellowish-white spots on upper side; epiproct with a pair of large spines laterally directed on posterior angle, apical half narrow distinctly. Type specimens are deposited in the College of Life Science, Leshan Normal University, Leshan 614004, China.
本文描述了采自中国四川的癞蝗属（Xya Latreille，1809）一新种——乐山癞蝗（Xya leshanensis sp. nov.）。它与日本癞蝗（Xya nitobei (Shiraki, 1913)）相似，但与后者的区别在于：触角节顶端部分的宽度几乎与基部相同；前胸背板宽度为其长度的1.25倍；后翅长，明显超过腹部末端；后足股节上侧有四个小黄白色斑点；肛上板后角有一对侧向的大刺，顶端半部明显变窄。模式标本保存于乐山师范学院生命科学学院，中国乐山614004。
