中国三节叶蜂属一新种(膜翅目,三节叶蜂科)

记述采自中国辽宁的三节叶蜂科1新种:Arge reversinervis sp.nov.。新种隶属于三节叶蜂属rustica-metallica种团,并与分布于日本的Arge abelivora Okutani近似,但新种触角亚端部强烈膨大,腹部和后足股节全部黑色,腹部背板具明显的微细刻纹,后足胫节基部4/5黄白色,各足基跗节大部浅褐色,OOL∶POL∶OCL=18∶11∶8 ,前翅C脉背侧大部暗褐色,R M脉几乎等长于Rs脉第1段, 2Rs室上缘显著短于下缘。新种后头强烈膨大,前翅2Rs室上缘显著短于下缘,腹部背板具明显刻纹,颜面具中纵脊,体具铜色光泽,可与同属已知各种鉴别。模式标本保存于中南林业科技大学模式昆虫标本室。
