Two species, Xenogryllus transversus (Walker, 1869) and Xenogryllus marmoratus (Haan, 1842), were known to reside in China from previous studies. However, the distribution of X. transversus in China derives from misidentification. Specimens from Yunnan Province, misidentified as X. transversus in earlier studies, are recognized as Xenogryllus maichauensis Gorochov, 1992 in this study. Another large Xenogryllus species found from Guangdong Province is identified as X. ululiu Gorochov, 1990. Both species are recorded in China for the first time. In this article, all known species of genus Xenogryllus from China are described and illustrated and a key to Chinese species of Xenogryllus is presented.展开更多
