Abstract

This study describes Syntomernus ningbonensis sp. nov. (Hymenoptera: Braconidae, Braconinae), a new species of Braconinae reported from China. This parasitoid wasp attacks cynipid gall wasps (Cynipidae) on Rosa multiflora leaves. Adult wasps emerge from host galls between late July and early October, with typically 3–5 conspecific adults emerging from a single gall. Phylogenetic relationships between the new species and S. flavus Morley, as well as other known Syntomernus species were inferred using partial mitochondrial cytochrome c oxidase subunit I (COI) gene sequences. Additionally, a new combination is proposed: S. garugaphagae (Ranjith & Quicke, 2016), comb. nov.
