ZooKeys 950: 41–49. https://doi.org/10.3897/ zookeys.950.48795 Abstract Oomyzus flavotibialis sp. nov. is described from Liaoning and Shandong provinces, China. Oomyzus galleru- cae (Fonscolombe) is reported for the first time from China. A key to Chinese species ofOomyzus is provided. Keywords Chalcidoidea, new species, taxonomy, Tetrastichinae Introduction The genus Oomyzus currently contains 26 valid species worldwide (Noyes 2019), with only four species known from China: O. scaposus (Thomson), O. sokolowskii (Kurdju- mov), O. sinensis Sheng & Zhu, and O. hubeiensis Sheng & Zhu (Li 1984; Sheng and Zhu 1998; Wang et al. 1998). Most species of the genus are parasitoids of Coleoptera, Neuroptera, Diptera, and Lepidoptera. They attack larvae or pupae, and even eggs of their hosts, and several species were widely used in classical biological control (Yaseen 1978; Alam 1982; LaSalle 1994; Liu et al.
