跳小蜂科一中国新记录属及一新种记述

Reports of a new record genus and description of a new species of Encyrtidae(Hymenoptera:Chalcidoidea)from China

【目的】为进一步丰富我国以及海南省生物多样性编目,发掘我国跳小蜂科寄生性天敌资源,在海南省9个市县开展了跳小蜂采集工作。【方法】通过体视显微镜,对在海南省通过黄盘诱集法获得的千余跳小蜂标本进行检视,利用传统分类学方法,以外部形态特征为依据进行分类研究。【结果】鉴定出跳小蜂科1新种,并详细记述了其雌成虫的形态特征,并附特征照片。与相近种进行对比分析,编制了古北区和东洋区种类的分种检索表。【结论】新种命名为海南阔角跳小蜂(Zaplatycerus hainanensis sp.nov.),为该属在我国首次报道。

【Objective】The study aimed to enrich the biodiversity of Hainan Province and China,and explore the resources of parasitic natural enemies,by collecting Encyrtidae among nine cities and counties of Hainan Province.【Method】More than 1000 specimens,collected using a yellow plate trapping in Hainan Province,were examined under stereomicroscope.As a traditional method,morphological characteristics were based for a taxonomic study.【Result】One species was discovered to be new to science.Morphological characteristics of the adult female were described in detail with characteristic photographs.Differences among closely related species were discussed,and a key to Palearctic and Oriental species was provided.【Conclusion】The new species was named as Zaplatycerus hainanensis sp.nov.,and the genus was first recorded in China.
