Abstract: Following studies of the aculeate families Bethylidae, Chrysididae, Formicidae, and Apidae, we report here the Diapriidae, the fifth hymenopteran family from the middle Miocene Zhangpu amber of China. A fossil species belonging to Trichopria Ashmead, 1893 is described and figured from a male specimen. The new extinct species, Trichopria electrosinica n. sp., is characterized by the subround and hypognathous head, the flagellomeres each with 6–8 long setae, the metanotum with longitudinal keels, the petiole two times longer than wide and carinate, and the fore basitarsomere with a row of setae along the inner margin. Trichopria is one of the largest diapriid genus, with some species used in pest control program against fruit flies, but Trichopria electrosinica n. sp. is its first described fossil species. Its absence in older and long-known deposits is indicative of the disparate Diapriidae fossil record. Its occurrence in both China and Dominican Republic during the Miocene suggests that the genus was already widespread at that time.
