中文摘要： 树甲族为拟步甲科中物种多样性较为丰富的一个类群，目前，由于研究基础差、栖息环境特殊、物种表型相似和树甲属物种数量庞大等特点，造成其本底不清、疑难种多和种类界定困难；树甲族属间系统发育关系、中国树甲属种团划分及其划分标准的研究也近乎空白，我国该类群虽有零散报道，但总体上缺乏全国性的系统研究。本项目以中国树甲族昆虫为研究对象，在广泛采集和借阅标本、核对模式标本的基础上，应用比较形态学和支序系统学等现代理论和方法，填补物种多样性研究的不足，并使其种类界定明朗化；在此基础上对中国树甲族属间的进化关系和分类地位、树甲属种团划分及其划分标准等问题进行合理地阐述和揭示。本研究对于澄清中国树甲族系统学研究中存在的混乱问题具有重要意义，同时也可为世界树甲族昆虫的研究奠定坚实基础。

英文摘要： The species diversity of the tribe Stenochiini is rather rich in the family Tenebrionidae, currently, there are some problems of uncertain numbers of the species, so many doubtful species and difficulty of the species identification because of the weak basis of research, the special habitats, similar phenotype of species and large quantity species of the genus Strongylium; the research of the phylogenetic relationship among the genus, species-group division of Chinese Strongylium and the diagnosis of species-group division hasn’t been done, a systematics of all Chinese Stenochiini is needed although some work has already been done. In the project, we attempt to deal with Chinese species of Stenochiini, then supplement species diversity data, reveal the classification status and phylogenetic relationship among the genus of Stenochiini. But all these researches must be based on specimens collection and borrow, and type specimen examination. Besides the consultion of comparative morphology, evolutionary taxonomy, species-group division of Strongylium and the the diagnosis of species-group division are necessary. The project is very important for clarifying taxonomic confusion of the tribe Stenochiini from China and laying the foundation for the study of global Stenochiini.
