中国距蟋亚科组系统分类研究（直翅目：蟋蟀科）

距蟋亚科组昆虫生境特殊、生殖隔离机制独特且地理分布复杂多样，是研究生态分布、生殖行为和生物地理学的理想材料，近年来一直受到学者们的广泛关注。但其分类学研究一直较为滞后，尤其在我国长期存在家底资源不清、属种分类混乱和系统发育研究空白等问题。鉴于此，申请人拟在前期工作基础上，通过整合国内和国际相关资源，进一步运用比较形态学的研究方法，从中探索并筛选出种、属级阶元界定的关键形态指标，并对中国距蟋亚科组进行全面修订，厘定已知属种的同物异名和地位归属等分类学问题，发现并描记新单元，阐明其属种多样性与地理分布情况；进而在世界范围内选取代表属，基于形态学数据，利用支序系统学原理和方法，对距蟋亚科组进行系统发育研究，提出相应推断和结论，为该类群乃至蟋蟀科分类系统的完善积累资料，从而有力提高我国在蟋蟀科系统学研究中的国际影响力。

The Podoscirtinae group of Gryllidae lives in different habitat from others and possesses special mechanism of reproductive isolation and diverse geographical distribution. Recently, it has attracted much attention because of being a good material to study the ecological distribution, reproductive behavior and biogragraphy. However, the taxonomy of this group has been lagged behind other studies all the time, especially in the Chinese fauna. In China, we are confronted with the following problems: the poor faunal investigation, few revision work and no phylogenetic study. For this reason, we will further focus on the systematic study of Podoscirtinae group from China in this project, based on our previous study. By the comparative morphology of combined material from demestric and overseas museums, we will explore and obtain the critical characters in defining the genera and species. Based on the latter result, we will revise the known Chinese taxa and clarify the taxonomic problems by the examination of the type specimens, then discover and describe the new taxa of the unsorted material. Furthermore, we will analyse the species diversity and distribution characters of this group from China. Moreover, we will choose some worldwide representive genera of Podascirtinae group and product the phylogenetic tree by the cladistics, which is based on the morphological data, then make a reduction and conclusion on the result. Through this project, we will make a good contribution to knowing the biodiversities of Chinese crikets better and providing some material to perfect the classification of Glyllidae. In the long run, we will enhance our Chinese force in the systematics of crikects in the world.
