摘　　要：记述在华北和华东地区严重危害白蜡的一种膜翅目叶蜂科食叶新害虫:白蜡敛片叶蜂Tomostethus fraxini Niu&Wei,sp.nov.。其单眼后区强烈隆起,宽长比约等于2;触角第3节微长于第4、5节之和;体和足全部黑色,体毛银色;中胸前侧片下部具宽阔裸带;腹部背板具微细刻纹,锯鞘毛黑褐色,伸向后方等,与本属其他种类明显不同。敛片叶蜂属(Tomostethus Konow)在国内也是第一次确定性报道。比较山东种群与北京种群的线粒体基因组差异,确定两地种群属于同一种类。比较白蜡敛片叶蜂与已报道cox 1数据的2种敛片叶蜂之间的cox 1差异,白蜡敛片叶蜂与黑毛敛片叶蜂和黄肩敛片叶蜂的差异十分显著。为便于本属害虫鉴定,编制了敛片叶蜂属世界已知种类检索表。In this paper,a new defoliator of Fraxinus spp.,Tomostethus fraxini Niu&Wei,sp.nov.,which seriously damages ash trees in North and East China,is described.T.fraxini differs from its congeners by the following characteristics:the postocellar area is strongly elevated with about 2 times the broad to long ratio;the third antennomere is slightly longer than the fourth and fifth antennomeres together;the body and legs are entirely black with silver body hairs;mesepisternum with a broad glabrous band in lower third;the abdominal tergites finely coriaceous;the setae on lateral of sheath black brown and extending backwards.Tomostethus Konow is also firstly reported formally in China.The differences in the mitochondrial genomes of the Shandong population and the Beijing population were compared,and the two populations were determined to be the same species.The genetic distances in cox 1 between the new species and the two previously reported Tomostethus spp.were compared.The result showed that the differences between them were very significant.In order to facilitate the identification of the pests of this genus,a key to the world known species of the genus was provided.
