The hymenopteran parasitoid complex of the families Eurytomidae and Pteromalidae associated with Lixus subtilis Boheman, 1836 (Coleoptera, Curculionidae) developing on sugar beet is studied in China (Xinjiang region). Eurytoma curculionum Mayr, 1878 (Eurytomidae) was reared from the larvae of Lixus subtilis and recorded for Xinjiang, China, for the first time. A new species, Chlorocytus papahemii sp. nov . (Pteromalidae), a hyperparasitoid of E. curculionum , is described from China. Illustrations and a detailed morphological description of the new species, as well as a redescription of the types of related Chlorocytus species, are provided. An identification key for females of the Chlorocytus harmolitae species is given.
