摘　　要：记述采自中国北方尖翅蝇属Lonchoptera Meigen 2新种,即纤毛尖翅蝇L.ciliosa,sp.nov.和多鬃尖翅蝇L.multiseta,sp.nov.,讨论了它们与近缘种的区别。并首次记录了亮额尖翅蝇L.nitidifrons Strbol在中国的分布。模式标本保存在中国农业大学昆虫博物馆。Two new species, Lonchoptera ciliosa, sp. nov. and L. multiseta, sp. nov., are described. L. nitidifrons Strobl is recorded from China for the first time. The types are deposited in the Entomological Museum of China Agricultural University, Beijing. 1. Lonchoptera ciliosa, sp. nov. （Figs. 1-7） The new species is somewhat similar to L. orientalis （Kertész）, but it can be separated from the latter by the mesonotum brown without stripes; pregonite weakly incised medially and hairy apically, and postgonite broad and sheet-like with narrower tip. Holotype： ♂, Shanshuping （33°13′N, 107°34′E）, Changqing nature Reserve, Yangxian County, Shaanxi Province, 29-Ⅶ-2006, ZHU Ya-jun; Paratypes： 3♀♀, the same data as holotype. Etymology. The specific epithet name refers to the hairy apex of the pregonite. 2. Lonchoptera multiseta, sp. nov. （Figs. 8-16） The new species is somewhat similar to L. bifurcata （Fallén）, but it can be separated from the latter by the halter dark brown, cercus longer than the epandrium and pregonite with two rows of rather long bristles at middle. Holotype： ♂, Xinglong Mountain （35°79′N, 104°07′E）, Yuzhong, Lanzhou City, Gansu Province, 21-Ⅷ-2007, HUO Shan; Paratypes： 2♂♂, same data as holotype. Etymology. The new species is named for the pregonite having two rows of rather long bristles at middle.
