Description

A new species of Diglyphus Walker, D. albifemur Liu, Hansson & 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 Phytomyza vitalbae Kaltenbach, mining leaves of Clematis orientalis L. The new species is morphologically similar to the European species D. clematidis Navone & Hansson and shares the same host plant genus (Clematis) 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 Diglyphus species by Zhu et al. (2000) was extended to incorporate the new species and all other Chinese species described since that publication.
