摘要：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 cox1 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. ? 2022 Chinese Society of Forestry. All rights reserved.
