Description of four new species of Idris Förster, 1856 (Hymenoptera: Scelionidae) from India

Four new species of Idris Förster, 1856 exhibiting gregarious parasitism, Idris bianor Sushama, Rajmohana & Debnath sp. nov, Idris furvus Sushama, Rajmohana & Debnath sp. nov, Idris hyllus Debnath, Rajmohana & Sushama sp. nov, and Idris longiscapus Debnath, Rajmohana & Sushama sp. nov. are described from India. A molecular phylogenetic analysis based on the mitochondrial cytochrome c oxidase I (mt COI) gene is presented to support species delimitation. The study emphasizes the need for more sampling of the Oriental fauna of Idris, followed by voucher-based integrated taxonomic studies.
