摘要: 宽背曲姬蜂[Scambus(Scambus)latustergus]是曲姬蜂属Scambus Hartig的一个新种,是寄生樟子松梢小卷蛾幼虫的一种新天敌。本新种与短角曲姬蜂[Scambus(S-cambus)brevicornis Grav.]和球象曲姬蜂[Scambus(Scambus)sudeticus Grow.]对樟子松梢小卷蛾幼虫的寄生率达44.4%,占整个幼虫期天敌的90%以上,因此这三种姬蜂在生物防治上很有应用价值。模式标本保存在中国科学院动物研究所。

Abstract: In this paper a new species of the genus Scambus Hartig is described, whichis a new naturnal enemy of Rhyacionia pinicolana (Doubleday). The typespecimens are preserved in the Institute of Zoology, Academia smica. Scambus(Scambus) latustergus Wang sp. nov. Female : Front wing 8 mm long, Male : Front wing 5mm long This species is similar to Scambus (Scambus)buolianea Hartig and Scambus(Scambus) detrita Holmgren, but may be separated from the former by : the bodymore big, front wing 8 mm long and stigma light yellow, the abdominal ter-gite 2 with even punctures, front femur of male with wide and deep hollow,and from the latter by : the abdominal tergite 1 clearly broader than long,hind tarsus not swollen, ovipositor 1.2 times as long as abdomen, thoraciclength of male 1.5 times as its height. Holotype : Hulun Buir League, Nei Mongol. Aut. Reg. 17, Ⅶ. 1989;Allotype : locality ditto, 20, Ⅶ. 1989; paratypes : 19, 4, ditto.
