Study of the Chinese species of Copidosoma Ratzeburg, 1844 (Hymenoptera: Encyrtidae)

Twenty-two Chinese species of Copidosoma are studied. Two species, C. baii and C. phalonitae, are described as new to science. Thirteen species are recorded from China for the first time: C. albipes, C. anceus, C. ancharus, C. at-etas, C. boucheanum, C. chalconotum, C. flagellare, C. fuscisquama, C. peticus, C. serricorne, C. subalbicorne, C. terebrator, and C. tibiale. Two synonymies are proposed: C. dailinicum (of C. sosares) and C. heliothis (of C. primulum). A key to species is given and photomicrographs are provided to illustrate morphological characters of the species.
