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. phaloniae , are described as new to science. Thirteen species are recorded from China for the first time: C. albipes , C. anceus , C. ancharus , C. aretas , 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.
