Highlights: • Black soldier fly (BSF) is beneficial in various bio-recycling & manure industries. • With copious protein content, BSF is an alternative for fish and animal feed. • Six hymenopteran parasitoids are reported to attack immature of BSF from India. • Two new species Eniacomorpha bouceki, and Calyoza hermetiae are described. Abstract: 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 Bouček 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.
