Hymenopteran parasitoids of the black soldier fly (BSF) Hermetia illucens (Linnaeus, 1758) (Diptera, Stratiomyidae), are recorded from southern India. Two new species, Calyoza hermetiae Binoy, & Colombo sp. nov. (Bethylidae, Epyrinae) and Eniacomorpha bouceki Binoy sp. nov. (Chalcididae, Dirhininae) are described and illustrated. Spalangia cameroni Perkins, S. obscura Boucek and S. simplex Perkins (Spalangiidae, Spalangiinae) and Dirhinus anthracia Walker (Chalcididae, Dirhininae) are also reported from BSF and are diagnosed and illustrated. A key to the hymenopteran parasitoids of BSF respectively belonging to Bethylidae (1 sp.), Chalcididae (4 spp.), Diapriidae (1 sp.), Spalangiidae (3 spp.), is provided. This study forms the first record of a host for Calyoza. Finally, the negative impact of these parasitoid assemblages on BSL is discussed.
