钮襀亚科隶属襀翅目、襀科，其稚虫生活在多种水域中，对水质敏感，可作为水资源污染监测的指示生物，因此开展该类昆虫的分类订正及系统发育研究具有重要的实际意义和科学价值。本研究目的在于基本查清我国钮襀亚科的种类组成及区系分布特点，实现对东洋区钮襀亚科分布的全面、准确认识。通过形态和分子特征的研究，获取钮襀亚科系统分类的形态和分子指标体系，规范简明属种特征，建立一批科学上的新分类单元，并对我国早期发表的属种进行考订；同时，应用支序分析法分析该类群的系统发育关系，确定锤襀属和华钮襀属的系统地位以及族级分类单元的划分，修订和完善其分类系统。这些研究成果将促进该亚科乃至整个襀翅目系统分类水平的提升，也为该亚科世界性的修订工作提供重要材料；同时也为世界襀翅目的地理分布、起源和演化研究提供重要的基础数据，为中国动物地理区系和系统进化动物学的研究提供理论依据。

The insects of Acroneuriinae (Plecoptera: Perlidae) live in a variety of the water and can be used as indicative organism for monitoring water pollution due to more sensitive to the water pollution. There will be very important practical significance and scientific value if carrying out researches on taxonomy and phylogeny of this group. This program aims to clear up the species composition and the characteristics of the fauna of Acroneuriinae in China, and to achieve a comprehensive and accurate understanding of acroneuriins distributed in the Oriental region. Based on the studies of the morphological and the molecular characteristics of acroneuriins, the index system for classification system will be obtained, and the characteristic pattern of species and genera of this group will be set up. Based on the characteristic pattern, the new taxa will be established, and early published species of acroneuriins from China will be revised. The phylogenetic relationships of species, genera and tribes will be set up by the method of cladistic analysis. Based on the phylogenetic relationships of Acroneuriinae, the taxonomic status of Claassenia and Sinacroneuria and tribe level taxa will be determined, and the classified system of this group will be revised and perfected. The results of these studies will promote the classification level of Acroneuriinae and even Plecoptera upgrade, and also provides important materials for the world's revised studies of the subfamily. Meanwhile, these results not only provide important research data of the geographical distribution, origin, evolution of Plecoptera all over the world, but also provide theoretical basis for Chinese fauna and systematic evolutionary zoology.
