小艳瓢虫亚科昆虫是介壳虫和粉虱类害虫的重要捕食性天敌，也是最原始的瓢虫类群之一，具有重要系统地位和重要经济意义。目前该亚科缺乏全面系统的分类修订，系统发育研究依然空白。本项目拟对我国小艳瓢虫亚科分类和系统发育深入研究，摸清我国该亚科的种类组成，明确鉴别特征，解决疑难属种的鉴定问题,订正各级分类单元，记述新的分类单元。基于形态数据和分子数据，重建属级以上系统发育关系，对高级分类单元进行修订，并进一步确立小艳瓢虫亚科各族在瓢虫科昆虫中的分类地位，完善小艳瓢虫亚科分类系统，提升我国的瓢虫科分类研究水平，为该类瓢虫的引进、保护和利用提供理论基础。

Ladybirds of Sticholotidinae are most important predators of scales and whiteflies, one of the most original ladybird groups, which play important roles in coccinellid phylogeny system and are significant in agricultural economy. At present, the taxonomy of Sticholotidinae lacks detailed revision and the phylogeny is unknown. In this project, the taxonomy and phylogeny of Sticholotidinae will be studied. It would be focus on the following scopes: collect and identify all Chinese species, make certain the morphological characters of each species, revise the taxonomic taxa, describe new genera and species, rebuild the phylogeny tree of Sticholotidinae based on morphological and molecular data, make revisions of each tribe and genera, fix the tribe positions in whole Coccinellidae, and perfect the taxonomic system. It is hoped that this project would elevate the research level of Chinese coccinellid taxonomy, and provide theoretical foundation for introducing, protecting and utilizing Sticholotidinae insects in biological control.
