| 摘 要： | <正> 寄生甘蔗绵蚜 Oregma lanigera(Zehntner)的蚜茧蜂全世界迄今仅知一种 LipolexisOregma(Galan),是 Gahan 于1932记载在菲律宾巴厘岛采得,国内、外其他地方均未见报道。国内各省蔗区的甘蔗绵蚜为害甚感严重,多年来尚未找到蚜茧蜂。笔者1980年6月在武夷山自然保护区内采到一种寄生甘蔗绵蚜的蚜茧蜂,经鉴定系一新种,是全世界寄生甘蔗绵蚜的第二种,也是该属 Lipolexis 在全世界的第四种。Lipolexis 属已知的3种,与本文增加的1新种,可根据下列检索表鉴定。

| Abstract: | This paper describes a new species,Lipolexis wuyiensis Chen from Bohea Hills of China.This new species can be distinguished from the other three known species of the genus by the following key. Key to the species of Lipolexis Forster(♀♀) 1.Tergite 1 with strongly prominent central bifurcating carina.Coloration mostly brownish-black.——Lipolexis gracilis Forster Tergite 1 without prominent central carina.Coloration mostly yellow——2 2.Tergite 1 with slightly prominent lateral longitudinal carinae.Ovipositor sheaths straight.Tentorio-ocular line equal to 1/5-1/6 of intertentorial line.——Lipolexis scutellaris Mackauer Tergite 1 without prominent lateral longitudinal carinae.——3 3.Ovipositor sheaths prolongated,somewhat dilated at apex,curved down- wards.——Lipolexis oregmae(Gahan). Ovipositor sheaths prolongated and boreral-form,not dilated at apex and not curved downwards.—— ——Lipolexis wuyiensis Chen sp.nov.(Fujian) Lipolexis.wuyiensis Chen,sp.nov. Body:lenth 2.5 mm. Holotype,♀,Bohea hills of Fujian,17 June,1980 from Oregma lanigera (Zehntner),on Phalris arundinacea L.(Chen Jia-hua). Male:Antennae 13 segmented,a little more robust and longer than in female: Tergite 1 with strongly central bifurcating carina.Otherwise like female except sexual characters. Allotype,(?),Topotypical,with same data as the holotype. Paratypes,1(?)15♀♀,Topotypical with holotype;17 June,1980(Chen Jia-hua).5♀♀,29 September,1980(Huang Ju-chang). Deposited at the Fujian Agricultural College. This species differs from Lipolexis oregmae(Gahan)in the shape of ovi- positor sheaths of female genitalia,areola of propodeum pterostigmal Cplora- tion and tergite 1.This species differs from Lipolexis sutellaris Maekauer in the tentorio-oeular line equal to half of intertentorial line and the shape of propodeum. |
