6th International Congress of DipterologyRecent findings on the fruit flies of Qianghai-Xizang Plateau(Diptera: Tephritidae)Chen, X.-l. & X.-j.WangInstitute of Zoology, Chinese Academy of Sciences, Beijing 100080, ChinaThe Qianghai-Xizang Plateau is known as the roof of the world. Theinsect fauna of Qianghai-Xizang Plateau is very complicated and itsvertical distribution is magnificent. The Plateau attracts a great number ofscientific works over the world by its mystic magnificence.Although the Chinese fauna of fruit flies has been comprehensivelyreviewed in 1996, but recent research on more materials and especiallyfrom the new specimen collected in Qianghai-Xizang Plateau within recentthree years have shown that the diversity of Tephritidae in China is muchrich than we have imagined, especially in this special area. Until now,thirty genera have been recognized, with 64 described species; 4 generaand 17 species are recorded to this region for the first time. Except that, atleast 7 species have high possibility being new to science. The majority ofthe taxa (over 70%) are Oriental, and others, Palearctic.The following research are going on: Firstly, the comprehensivescientific expedition to the Qianghai-Xizang Plateau will be carried on innext two years and more fruit flies will be collected and recognized;Secondly, phylogeographic implications of Cornutrypeta Han et Wang,Stemonocera Rondani and Ortalotrypeta Hendel in this region will becarefully discussed; Lastly, the sudden ascent of Qianghai-Xizang Plateauin relation to the fruit fly fauna of this region will be tentatively studied.Key Words: recent findings, fruit flies, Qianghai-Xizang Plateau, newrecord, new species∗∗∗∗∗∗∗∗∗∗42
