Abstract: A serious invasive pest, Ophelimus maskelli (Ashmead) (Hymenoptera:Eulophidae), occurred in China in recent years. The pest forms many small galls on the leaves of Eucalyptus trees and caused defoliation. For biological control of the pest, investigation of its natural enemy was carried out. An effective parasitoid species, Closterocerus chamaeleon (Girault) (Hymenoptera:Eulophidae), was discovered by rearing the Eucalyptus leaves with galls. It is the first record of the parasitoid in China and thus was morphologically described in detail in the present paper with color photos provided. Meanwhile, the diagnostic characters that distinguish the new parasitoid from other close species in the genus were provided. The parasitoid species originally distributes in Australia and now has invaded into many countries in the world where the trees are cultivated, where the parasitoid is a superior natural enemy for the gall maker pest. Therefore, the parasitoid species could play an important role in managing the pest in China.

Key words: Closterocerus chamaeleon, parasitoid, a new species to China, Ophelimus maskelli, invasive pest
