摘　　要：金小蜂昆虫是一类重要的寄生性天敌资源,可广泛应用于防控农林牧业的害虫。本文采用形态分类方法和DNA条形码技术,对采自新疆的金小蜂属Pteromalus标本进行研究,发现了青绿金小蜂种团Pteromalus albipennis-Group,并鉴定出3个中国新记录种:长腹青绿金小蜂Pteromalus elevatus(Walker,1834),青绿金小蜂Pteromalus albipennis Walker,1835和类青绿金小蜂Pteromalus temporalis(Graham,1969)。本文对这3种金小蜂作了形态描述,提供了鉴别特征图及ITS2条形码,编制了中国金小蜂属的分种检索表。研究结果将为查明中国金小蜂属本底资源,以及后期开发利用该类群防治新疆本地的农林牧害虫提供前期理论依据,具有重要的理论研究意义和实践指导价值。Pteromalids are an important parasitic natural enemy resource widely used in pest control in agriculture,for⁃estry and pasture.In this study,specimens of Pteromalus collected from Xinjiang were identified by morphological charac⁃terization and DNA barcoding.The Pteromalus albipennis-group,including three new record species from China:P.elevatus(Walker,1834),P.albipennis Walker,1835,and P.temporalis(Graham,1969)was identified.Descriptions,ITS2 barcodes,and morphological pictures for these three species,and a key to all the known Chinese species of Pteromalus,are provided.The investigation of Pteromalus taxonomy in Xinjiang enhances the knowledge of Pteromalus genus in China,and also provides important data for the potential use of these parasitoids to control local pests in Xinjiang.
