Integrated taxonomy unveils three new species of Foenobethylus (Hymenoptera, Bethylidae) from China

Species of the genus Foenobethylus Kieffer, 1913 are parasitoids wasps rarely collected and are only found in the Oriental region. In this study, based on both morphological and molecular evidence, we describe three new species from China: F. robusta Li & Chen, sp. nov., F. xinglongsensis Wang & Chen, sp. nov., and F. yunkaishanensis Chen & Luo, sp. nov. An updated key to species of the genus is provided. Additionally, the phylogenetic relationships between Foenobethylus and other three morphologically similar genera are discussed based on the analyses of COI and 28S genes
