摘要
首次报道跃姬蜂属Xenoschesis Förster,1869在四川、甘肃、青海的分布,并报道该属1新种:红斑跃姬蜂Xenoschesis(Polycinetis)rufimacula Li,sp.nov..该新种与黑跃姬蜂Xenoschesis(Polycinetis)melana Sheng,Sun&Li,2020相似,与后者的区别主要是:侧单眼间距约为单复眼间距的1.2倍,中胸侧板中央纵向呈细粒状表面,腹部第1节背板长约为端宽的2.0倍,腹部第2节~第4节背板红色、腹板红褐色;黑跃姬蜂的侧单眼间距约为单复眼间距的0.9倍,中胸侧板中央光滑无粒点,腹部第1节背板长约为端宽的1.7倍,腹部全部黑色.详细描述了该种的形态特征,提供了鉴定特征图.模式标本保存于国家林业和草原局生物灾害防控中心昆虫博物馆.

In this study,Xenoschesis Förster,1869 was first discovered from Sichuan,Gansu and Qinghai provinces and a new species,Xenoschesis(Polycinetis)rufimacula Li,sp.nov.was identified.This new species is similar to X.(Polyci-netis)melana Sheng,Sun&Li,2020,but can be distinguished from the latter by the following combinations of charac-ters:postocellar line approximately 1.2×as long as ocular-ocellar line;median portion of mesopleuron with fine leathery texture;tergite 1 approximately 2.0×as long as apical width;tergites 2-4 red,sternites 2-4 reddish brown.X.(Polyci-netis)melana:postocellar line approximately 0.9×as long as ocular-ocellar line;median portion of mesopleuron smooth;tergite 1 approximately 1.7×as long as apical width;metasoma black.The illustration and description are provided.The specimens examined are deposited in the insect museum,Center for Biological Disaster Prevention and Control,National Forestry and Grassland Administration.
