摘要：
In this paper, a new species, Megaxyela leucostigma sp. nov., of the genus Megaxyela from Tianmu Mountain, Zhejiang Province, China, is described and it is possibly a new pest of Carya cathayensis. The new species obviously differs from the known species of the same genus by the wings entirely hyaline with milky white pterostigma and veins as well as the apical ovipositor sheath yellowish white. M. leucostigma is sympatric with M. euchroma Blank, Shinohara & Wei, 2017 and they may have the same host of Carya cathayensis of Juglandaceae, but the new species differs from M. euchroma by the narrow apical sheath. The K2P distance between the COⅠ of M. leucostigma and M. euchroma is 10.85%, which is similar to the interspecific distance of other species of the same genus (7.6%-13.5%). A key to Asian species of the genus Megaxyela is provided. © 2021, Editorial Department of Scientia Silvae Sinicae. All right reserved.
