Abstract

<br> A new species of<br> Diglyphus<br> Walker,<br> D. albifemur<br> Liu, Hansson &amp; Guo, sp. nov., is described based on extensive material from China collected from 2016 to 2024. The entire material included here has been reared from agromyzid leafminers (Diptera, Agromyzidae), mainly from<br> Phytomyza vitalbae<br> Kaltenbach, mining leaves of<br> Clematis orientalis<br> L. The new species is morphologically similar to the European species<br> D. clematidis<br> Navone &amp; Hansson and shares the same host plant genus (<br> Clematis<br> ) but can be distinguished by several diagnostic features detailed herein. Mitochondrial cytochrome c oxidase subunit I (COI) sequences of the new species are provided. The identification key to Chinese<br> Diglyphus<br> species by Zhu et al. (2000) was extended to incorporate the new species and all other Chinese species described since that publication.<br>
