【摘要】 沟胫天牛族(Lamiini Latreille 1825)是天牛科(Cerambycidae)沟胫天牛亚科(Lamiinae)中最大的族之一,很多种类是农林生产上的重要害虫。本文介绍了沟胫天牛族昆虫的经济重要性和国内外分类研究现状,分别研究了传统的外部形态特征、后翅翅脉特征,并对我国沟胫天牛族昆虫的区系进行了较细致的研究,主要研究结果如下:1.分类研究本研究整理了中国沟胫天牛族57属246种和亚种,描述了51属171种和亚种的成虫外部形态特征,其中根据标本鉴定和文献资料记载,新增加沟胫天牛族昆虫9属23种的中文外部形态描述和31种沟胫天牛族昆虫的分类历史资料,是目前我国沟胫天牛族昆虫成虫外部形态特征最全面的资料。编制了沟胫天牛族分属检索表和12属分种检索表。2.后翅翅脉研究本论文认为采用Kukalova and Lawrence(1993)的鞘翅目翅脉模式系统和命名法能更好的命名沟胫天牛族昆虫的后翅翅脉。比较研究了28属65种本族昆虫的后翅翅脉特征,并做了详细地描述。结果发现沟胫天牛族昆虫的后翅翅脉特征在族级以上具有分类学意义;但不具有属级和种级的分类学意义,仅可作为分类鉴定时的一种辅助参考。新增加拍摄了4属10种本族昆虫的后翅照片。3.中国沟胫天牛族区系研究本文对中国沟胫天牛族昆虫区系组成进行了研究,基本摸清了中国沟胫天牛族昆虫的分布。到2007年为止,我国已记录的沟胫天牛族昆虫有57属246种和亚种。由于调查的局限性,很多本族昆虫种类有待发现,各个种的分布情况也有待核实和补充。本论文仅就我国已记载的沟胫天牛族昆虫的区系分布进行了初步讨论,结果发现本族种类十分丰富,在两大界均有分布,但东洋界占绝对优势,南方区系成分占总数的85%以上。沟胫天牛族昆虫在我国7个区均有分布,而华南区最为丰富。根据区系研究结果,形成了中国沟胫天牛族昆虫名录。更多还原

【Abstract】 Lamiini is one of the biggest tribes in Lamiinae (Coleoptera: Cerambycidae) and many species are serious pests in agriculture and foresty. The dissertation introduces the economic significance and the study progress on Lamiini. Based on the shortage of study on Lamiini of China, the dissertation put emphasis on the external morphology, hind wing veinations and the fauna of Lamiini in China. Results are the followings:1. Study on external morphology of Lamiini adultThe dissertation recordes 57 genera and 246 species and subspecies of Lamiini distributed in our country and describes 51 genera and 171 species and subspecies adult. 9 genera and 23 species are firstly described in Chinese and classification histories of 31 species are added. Keys for genera and species are given in this thesis too.2. Study on venations of hind wingThe nomenature of Polyphaga in Coleoptera given by Kukalova and Lawrence in 1993 is suitable to name hind wing venations of tribe Lamiini. The dissertation carefully describes the hind wing venations and takes photos to all studied hind wings. 28 genera 65 species are described in the dissertation and 4 genera and 10 species are described firstly. Hind wing venation is stable in level tribe classification but not stable in level genus and species classification. So, hind wing venations can only be used to distinguish look-like species but not to establish the system of tribe Lamiini.3. The fauna of Lamiini in China I studied the fauna of Lamiini in China, give the list of tribe Lamiini distributing in China and known the constitute and distribution of species. Up to now, there are 57 genera and 246 species and subspecies in China. But many species of Lamiini are not found and these distributions of known species should be completed and justified. Lamiini distributes in the Palearctic Realm and the Oriental Realm, but mainly in the Oriental Realm (more than 85%). Lamiini distributes in the 7 zoogeographical regions of China.更多还原
