The tribe Cotesiini (Hymenoptera:Microgastrinae) is one of the largest groups of Braconidae, including approximately600described species of14genera. The majority of Cotesiini are endoparasitoids of larvae of Lepidoptera while a few species parasitize species of Coleoptera, Diptera and Tenthredinidae (Hymenoptera). Many species of the tribe are very important in natural control of agricultural and forest pests. The species of tribe Cotesiini from China are revised in the present work. This dissertation comprises two parts, general part and taxonomic part.The general part is mainly about taxonomic history of the subfamily Microgastrinae which includes the tribe Cotesiini. In the taxonomic part, about80species in6genera and1subgenus from China are recognized, of which37species are new to science, and1genus and14species are recorded from China for the first time.50previously known species of8genera from China with on specimens available for this study are also noted. Description of the known genus Pseudovenanides Xiao et You,2002is similar to that of the genus Deuterixys Mason,1981, while the types are not checked, so this genus is excluded from the key to genera of tribe Cotesiini from China. Information of diagonostic characters, distribution and hosts are provided for each genus, subgenus and species. Keys to genera, subgenera and species are also provided. In addition, authentically identified species deposited in the Netherlands Centre of Biodiversity Naturalis were checked to confirm the identification of some known species in this study.Types are all deposited in the Parasitic Hymenoptera Collection of Zhejiang University.
