【摘要】 本研究对东北林业大学昆虫标本室、中国科学院动物研究所、国家动物博物馆的馆藏阔柄跳小蜂属标本,以及本人通过饲养、网扫、黄盘诱集的方法采集的大量阔柄跳小蜂属标本进行了检视。整理和研究了阔柄跳小蜂属Metaphycus标本共计5000余号,其中玻片标本近200号。通过外部形态比较,对中国阔柄跳小蜂属Metaphycus开展了系统分类学研究。论文共分三章,第一章为绪论,介绍了阔柄跳小蜂属的研究历史和国内外研究概况；形态特征以及研究材料与方法。第二章为各论,记述了我国阔柄跳小蜂属32种,其中包括11个新种：棕脊阔柄跳小蜂Metaphycus dorsalis sp. n.,中国阔柄跳小蜂Metaphycus chinensis sp. n.、武氏阔柄跳小蜂Metaphycus wui sp. n.,长鞘阔柄跳小蜂Metaphycus stylatus sp. n.,黑柄阔柄跳小蜂Metaphycus fusiscapus sp. n.,褐翅阔柄跳小蜂Metaphycus fusiformis sp. n.,雅安阔柄跳小蜂Metaphycus yaanensis sp. n.,版纳阔柄跳小蜂Metaphycus bannai sp. n.、盔蚧阔柄跳小蜂Metaphycus corni sp. n.、食蚧阔柄跳小蜂Metaphycus rusciae sp. n.,三角阔柄跳小蜂Metaphycus deltoideus sp. n.;5个中国新记录种并给出了中文名：加蒙阔柄跳小蜂Metaphycus garmon Guerrieri&Noyes,2000、杰氏阔柄跳小蜂Metaphycus gerardi Sugonjaev,1996、亮光阔柄跳小蜂(?)Metaphycus nitens (Kurdjumov,1912)、东方阔柄跳小蜂Metaphycus orientalis (Compere,1924)、黑缘阔柄跳小蜂Metaphycus melanostomatus (Timberlake,1916)。同时详细描述了这些种的外部形态特征、成虫各部位照片和分种检索表。第三章为结论和讨论。本研究是我国阔柄跳小蜂属的首次系统分类研究,由于阔柄跳小蜂昆虫属于天敌昆虫,因此本项研究将对指导农林业生产防治等方面具有重要的意义。所有新种的模式标本均保存在中国科学院动物研究所。更多还原

【Abstract】 Taxonomic studies on Chinese species of the genus Metaphycus was conducted through the examination of nearly5000specimens (include sample slide about200) from the Insect Collections of Northeast Forstry University (NEFU), Institute of Zoology, Chinese Academy of Sciences (IZCAS), National Zoological Museum of China (NZMC), and the specimens collected by host rearing, sweeping, and yellow pan trap by myself in this paper.The paper comprises three parts. In Part I. introduction, the taxonomic history and current situation of studies, characteristics, the materials and methods of study were briefly introduced. In Part II. systematics, thirty species of the Metaphycus were identified, and nine species M. dorsalis sp. n., M. chinensis sp. n., M. wui sp. n., M. stylatus sp. n., M. fusiscapus sp. n., M. fusiformis sp. n., M. yaanensis sp. n., M. bannai sp. n. and M. deltoideus sp. n. were described as new to science; five species, M. garmon Guerrieri&Noyes,2000, M. gerardi Sugonjaev,1996, M, nitens (Kurdjumov,1912), M. orientalis (Compere,1924), M. melanostomatus (Timberlake,1916). Characteristics of all the species were described in detail, providing photos of adult and keys to Chinese species of adult female. Part III was conclusions and discussions.The present study was the first systematic revision of the genus from China. As an important category of natural enemy, most species of the genus are coccid-inhabiting parasites. Therefore, the present study is of significant importance on the guidance of control on agricultural and forestry pests.All the type specimens were deposited in Institute of Zoology, Chinese Academy of Sciences, Beijing, China.更多还原
