准确的α-分类学是生物学的核心，但基于单一学科的α-分类学总具一定的失败率，而当多学科相互弥补，不仅可以增加物种界定的严密性，而且可加速物种界定及描记的过程。螽斯亚科昆虫是开展行为学、谱系生物地理学及保护生物学等科学研究的理想对象，也是具有重要经济文化价值的景观昆虫。但我国对该亚科的物种分类、区系组成和行为学等方面的研究均较少，在其保护生物学及进化生物学研究方面尚属空白。本项目拟运用整合分类学的原理和方法，综合经典形态学、鸣声和分子生物学特征，基于多分支学科分类结果的一致性或累积性原则，在该亚科物种进行准确界定的基础上，系统深入地开展我国螽斯亚科的分类、区系组成和物种保护价值的研究，并探索重要属（种）的种群分化过程及影响因素。从而阐释我国该亚科物种的多样性分布格局及其形成机制，推动本学科的深入发展，并为进一步生物多样性、行为生态学、进化生物学及保护生物学等方面的研究奠定坚实的基础。

Good alpha taxonomy is the core of biology. Integrating multiple disciplines to solve taxonomic problems helps avoid failure inherent to single discipline, increases rigor in species delimitation, and accelerates the progress of species delimitation and description. Insects of the subfamily Tettigoniinae are ideal objects to study behavior, phylogeography and conservation biology, which also have importantly economic, cultural and ornamental values. Nonetheless, in China, there are few studies on taxonomy, fauna and behavior and no researches on conservation biology and evolutionary biology about the subfamily. Firstly, we will integrate morphological, acoustic and molecular characters to accurately delimit species of the Tettigoniinae in China by “consistence” or “cumulation” approach. Furthermore, we will conduct researches on the taxonomy, the faunal composition and the protection values of the species in China. We will also explore the population differentiation processes of important genera (species) and document factors which affected the population differentiation. Consequently, The project will illustrate the distribution patterns of species and process of species diversification of the subfamily in China, promote the further development of the disciplines, lay a solid foundation for researches on biodiversity, behavioral ecology, evolutionary biology and conservation biology etc..
