Biology. Species of Coelophithia were recorded as parasitioids of Lepidoptera ( Lasiocampidae , Noctuidae , Arctiidae and Nymphalidae ), Hymenoptera ( Tenthredinidae and Cephidae ), Diptera ( Cecidomyiidae ) and Coleoptera ( Curculionidae ). In our study, Gypsonoma minutara HÜbner ( Lepidoptera , Tortricidae ) and Pseudaletia separate Walker (Lepdoptera, Noctuidae ) are reported as new host records of the genus from China.

Distribution. China (Inner Mongolia, Hebei, Beijing, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan); Palearctic, Nearctic and Afrotropics Regions.
