摘　　要：对簇瘿蚊属Acinacistyla Fedotova & Sidorenko的属征进行修订,编写该属世界分种检索表(雄性),并记述采自贵州、云南、江西和河南四省的该属1新种,命名为短瓣簇瘿蚊Acinacistyla brevilobatasp.Jiaoet Bu,nov.,模式标本保存在南开大学昆虫标本馆。短瓣簇瘿蚊,新种Acinacistyla brevilobata Jiao et Bu,sp.nov.(图1～10)新种与分布于俄罗斯的柔毛簇瘿蚊Acinacistyla papposa Fedotova&Sidorenko在雄成虫外生殖节的抱器基节中基瓣及肛下板等特征相似,但区别明显:1)新种肛下板近端部两侧各着生1个约为肛下板长度1/3的端瓣,且该瓣不具关节状结构,而A.papposa肛下板近端部两侧各着生1个约与肛下板等长、在近基部1/3处具关节状结构的端瓣;2)新种抱器基节中基瓣的较长亚瓣卷曲并缠绕于阳茎;而A.papposa抱器基节中基瓣的较长亚瓣长棍状直立、且并不卷曲缠绕。正模♂,贵州梵净山护国寺(27.5°N,108.4°E;海拔1350m),2002-05-28～29,王新谱马氏网捕。副模:1♂,贵州道真县大沙河仙女洞(29.32°N,107.40°E;海拔600m),2004-05-24,朱卫兵马氏网捕;1♂,云南腾冲整顶(25.01°N,98.30°E;海拔1800m),2002-09-03～05,薛怀君马氏网捕;4♂♂,云南泸水姚家坪(25.59°N,98.49°E;海拔2450m),2002-09-16～18,薛怀君马氏网捕;2♂♂,江西井冈山小溪洞(26.28°N,114.14°E;海拔220m),2002-07-23～27,薛怀君马氏网捕;2♂♂,江西宜丰官山保护区东河站(27.07°N,114.09°E;海拔1000m),2002-07-29～08-01,薛怀君马氏网捕;1♂,河南栾川龙峪湾鸡角尖(33.66°N,111.75°E;海拔1600m),1996-07-13,李军网捕。模式标本保存在南开大学生命科学学院昆虫标本馆。词源:种名brevilobata为一阴性复合拉丁形容词,意为"短瓣的",指该种肛下板近端部两侧各着生1个相对于柔毛簇瘿蚊A.papposa较短的瓣。In this present paper, the genus Acinacistyla is transferred from the supertribe Brachineuridi to the tribe Ledomyiini of the supertribe Lasiopteridi. The generic diagnosis is revised and broadened and a key to males of the genus is given. One new species, A. brevilobata sp. nov. from China is described and illustrated. The type specimens are deposited in the Institute of Entomology, College of Life Sciences, Nankai University, Tianjin, China.
