An Annotated Checklist of Mymaridae (Hymenoptera: Chalcidoidea) in Taiwan, with Descriptions of Five New Species

台灣纓小蜂科(膜翅目:小蜂總科)名錄記述暨五新種描述

摘要


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.

本文有關台灣產膜翅目纓小蜂科名錄,包括每物種的分布與寄主訊息,總計28屬60種,其中13屬33種為新紀錄,以及Acmopolynema berezovskiyi sp. n., Anagroidea montana sp. n., Camptoptera jthuberi sp. n., Mymar alishan sp. n.與Ooctonus kokozai sp. n.等5個新種。本文也將Eubroncus Yoshimoto, Kozlov and Trjapitzin, 1972之模式種─Eubroncus orientalis Yoshimoto, Kozlov and Trjapitzin, 1972,進行雄成蟲重新描述,並以採自印尼蘇拉威西島的一件雌成蟲標本,進行首次描述。隨文檢附Eubroncus屬的物種檢索表,其中Eubroncus hani Jin and Li, 2014為Eubroncus indicus Hayat and Khan, 2009的新異名,該物種係以採自尼泊爾的雄成蟲標本為描述依據;本文另就Cosmocomoidea tenuis Xu, Lin and Hu, 2016與Eubroncus tibetanus Jin and Li, 2014,分別檢查來自台灣與日本的雄成蟲標本,進行描述。纓小蜂科為卵寄生蜂類,其某些成員為半翅目稻蝨科與葉蟬科等農業害蟲的重要天敵,在台灣之往昔記錄中對此等蟲種已有嚴謹之分析。
