A new species of the genus Traulia Stål, 1873 namely Traulia xiai sp. nov. is described from China in this paper. The new species is similar to Traulia brachypeza Bi, 1986, but differs from the latter by the short tegmina, reaching the middle of third abdominal tergite only. The new species is also similar to Traulia ornate Shiraki, 1910, but differs from the latter by hind tibia all orange red and furculae of male absent. We think that Traulia yifengensis Wang, Xiangyu & Liu, 1997 is a valid species, not a synonym of Traulia brachypeza Bi, 1985 by Wei & Huang (2012), because the tegmina of Traulia yifengensis is very long, extending over the end of abdomen distinctly. A key to 19 species of this genus from China is also given in this paper. The type specimens are deposited in the National Museum of Natural Science, Taichung, Taiwan, China.
本文描述了采自中国的斯氏菱蝗属（Traulia Stål，1873）一新种，即夏氏菱蝗Traulia xiai sp. nov. 。新种与1986年的短翅斯氏菱蝗Traulia brachypeza Bi相似，但区别在于其短翅仅到达第三腹节背板中部。新种也与1910年的华丽斯氏菱蝗Traulia ornate Shiraki相似，但区别在于其后足胫节全为橙红色且雄性无腹叉。我们认为1997年的宜丰斯氏菱蝗Traulia yifengensis Wang, Xiangyu & Liu是一个有效种，而非如魏和黄（2012）所认为的是1985年短翅斯氏菱蝗的同物异名，因为宜丰斯氏菱蝗的翅非常长，明显超过腹部末端。本文还给出了该属中国19个种的检索表。模式标本保存于中国台湾台中自然科学博物馆。
