Abstract:

    A checklist of the fairyflies (Hymenoptera: Mymaridae) known from Taiwan is presented, annotated with information on their distribution and host associations. There are 28 genera and 60 named species, among them 13 genera and 33 species are new records for Taiwan. The five new species described here are Acmopolynema berezovskiyi sp. nov., Anagroidea montana sp. nov., Camptoptera jthuberi sp. nov., Mymar alishan sp. nov., and Ooctonus kokozai sp. nov. The male of Eubroncus orientalis Yoshimoto, Kozlov and Trjapitzin, 1972 (the type species of the genus Eubroncus Yoshimoto, Kozlov and Trjapitzin, 1972) is redescribed, and its previously unknown female is described based on specimens from Sulawesi Island, Indonesia; an updated world key to the species of Eubroncus is provided. Eubroncus hani Jin and Li, 2014 syn. nov. is synonymized under Eubroncus indicus Hayat and Khan, 2009, whose male is described here based on specimens from Nepal; the previously-unknown males of Cosmocomoidea tenuis Xu, Lin and Hu, 2016 and Eubroncus tibetanus Jin and Li, 2014 are also described based on specimens from Taiwan and Japan, respectively. As egg parasitoids, some members of the family are important as natural enemies of agricultural pests, such as rice planthoppers and leafhoppers (Hemiptera: Delphacidae and Cicadellidae, respectively); previous records of these in Taiwan are critically analyzed.
