Microgastrine wasps (Hymenoptera: Braconidae) are primary parasitoids of Lepidoptera. Some of them parasitise major economic pests and have been largely used for biocontrol programs. We revise here the fauna of Reunion Island: 34 spe-cies were recorded, belonging to 13 genera. One genus and 18 species are newly described: Dodogaster gen. nov, Apan-teles minatchy sp. nov., A. pashmina sp. nov., A. romei sp. nov., Cotesia xavieri sp. nov., Dolichogenidea ashoka sp. nov., D. broadi sp. nov., D. lumba sp. nov., D. uru sp. nov., D. villemantae sp. nov., Distatrix yunae sp. nov., Dodogaster grangeri sp. nov., Exoryza safranum sp. nov., Glyptapanteles chidra sp. nov., Nyereria ganges sp. nov., N. mayurus sp. nov., Parapanteles covino sp. nov., P. darignac sp. nov. and Wilkinsonellus narangahus sp. nov.. On the remaining 16 species, 12 are new distribution records. Finally, Glyptapanteles antsirabensis (Granger) comb. nov., G. ficus (Granger) comb. nov., G. subandinus (Blanchard) comb. nov., and Venanides curticornis (Granger) comb. nov. are reassigned from the traditionally defined Apanteles genus to these respective genera. A key to all genera and species is provided.

Diversity, host association, and cocoon variability of reared Indian Microgastrinae (Hymenoptera: Braconidae)

Three new species of parasitic wasps (Braconidae: Microgastrinae) from southern India are described and illustrated. Glyptapanteles clanisae sp. nov., a remarkable gregarious endoparasitoid, was bred from the caterpillar of Clanis phalaris Cramer (Lepidoptera: Sphingidae) on the host plant Pongamia pinnata (L.) (Leguminosae) along with a hyperparasitoid, Eurytoma sp. (Eurytomidae). Glyptapanteles trilochae sp. nov., was reared from parasitized caterpillar of Trilocha varians (Walker) (Lepidoptera: Bombycidae) on the host plant Ficus racemosa L. (Moraceae) along with a hyperparasitoid, Paraphylax sp. (Ichneumonidae: Cryptinae). Buluka horni sp. nov. was collected from solitary cocoons of an indeterminate caterpillar feeding on Mangifera indica L. leaves. This study also confirms a host range extension of Indian species of Glyptapanteles to Bombycidae and Sphingidae in addition to the earlier documented families viz., Papilionidae, Nymphalidae, Arctiidae, and Noctuidae.

The unusual species of Cotesia (Hymenoptera, Braconidae, Microgastrinae) with the first tergite narrowing at midlength are reviewed. One new species, Cotesia trabalae sp. n. is described from India and compared with Cotesia pistrinariae (Wilkinson) from Africa, the only other species sharing the same character of all the described species worldwide. The generic placement of these two species, based on molecular and morphological analyses as well as parasitoid biology is discussed.

The Indian fauna of the genus Microplitis Foerster, 1862 is revised. An illustrated key to eight species including the description of one new species, M. murkyi sp. nov., is provided. Six previously described species, namely: M. ajmerensis Rao & Kurian, M. demolitor Wilkinson, M. indicus Marsh, M. manilae Ashmead, M. prodeniae Rao & Kurian, and M. spodopterae Rao & Kurian are elaborated with taxonomical variations and extended distribution. Two species, M. bageshri Sathe, Inamdar & Dawale and M. dipika (Bhatnagar) are considered incertae sedis. A new combination is suggested for Snellenius maculipennis (Szepligeti) which is placed into synonymy with Microplitis. Information on taxonomic history of the genus, diagnostic characters of all the included species, distribution and host relationships are provided.

Eight species of parasitic wasps were bred from various stages of five species of hesperiids viz. Thoressa evershedi (Evans), Pelopidas mathias (Fabricius), Udaspes folus (Cramer), Borbo cinnara (Wallace) and Caltoris sp. inhabiting Western Ghats, Kerala, India. One new species, Dolichogenidea kunhi Gupta & Kalesh, is described and illustrated from Kerala, India, and its relationship with closely allied species is discussed. This new species was bred from parasitized larvae of Thoressa evershedi (Evans) (Lepidoptera: Hesperiidae). Microgastrinae braconid species, Apanteles javensis Rohwer and Cotesia erionotae (Wilkinson) were bred from parasitized larvae of P. mathias and U. folus respectively. Brachymeria habui Özdikmen (Chalcididae) was recorded from pupae of U. folus. Two hyperparasitoids, Eurytoma manilensis Ashmead (Eurytomidae) & Pediobius foveolatus (Crawford) (Eulophidae) were bred from larvae of B. cinnara. Egg parasitoid, Ooencyrtus papilionis Ashmead (Encyrtidae) and pupal parasitoid Brachymeria lasus (Walker) (Chacididae) was recorded from Caltoris sp. Information on the parasitoid distribution, brief diagnosis of each species with a habitus photograph for easy identification, host association, host caterpillars, caterpillar host plants, and taxonomic comments are provided.
