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。In this paper a new species of the genus Scambus Hartig is described, whichis a new naturnal enemy of Rhyacionia pinicolana (Doubleday).
