A new species of Oomyzus Rondani (Hymenoptera, Eulophidae) reared from the pupae of Coccinella septempunctota (Coleoptera, Coccinellidae) in China

Oomyzus spiraculus Song, Fei & Cao sp. nov. (Hymenoptera, Eulophidae) is described and illustrated as a gregarious larval-pupal endoparasitoid of Coccinella septempunctata L. (Coleoptera, Coccinellidae). Differentiation between O. spins ulus and its similar species is discussed and a key to differentiate the female and male of these species is provided. DNA barcodes of O. spiraculus and O. scaposus are analyzed and compared.
