Abstract
BACKGROUND: The genus Orientoglypta Kuslitzky, 1973 (Hymenoptera, Ichneumonide, Banchinae) is a small taxon of ichneumonid wasps, comprising only three described species worldwide. Currently, there are no documented host records for any species. Prior to this study, Orientoglypta was poorly documented in China, with only a single species, O. lota, previously reported from Taiwan. NEW INFORMATION: Here, we report for the first time the presence of Orientoglypta in mainland China, reporting four new species and one known species: Orientoglypta lota (Chiu, 1965), O. laevis Gong & Chen, sp. nov., O. absenta Gong & Chen, sp. nov., O. densipunctata Gong & Chen, sp. nov. and O. aureocincta Gong & Chen, sp. nov. Additionally, a key to the world species of Orientoglypta is provided.
