综合支序系统学和几何形态学方法重建膜翅目旗腹蜂总科演化谱系图

旗腹蜂总科是膜翅目在侏罗纪大辐射时出现的一个重要类群，延续至今既包含灭绝的化石类群，又具有丰富的现生类群。本项目将以中国，缅甸中生代丰富的旗腹蜂总科昆虫化石为研究对象，着眼于科学研究前沿：（1）开展大量中生代旗腹蜂总科昆虫化石类群的经典分类工作，厘清中国，缅甸中生代旗腹蜂总科的类群构成，修订存疑属种；（2）分析重要形态特征（如蜂腰结构）的演化轨迹与功能形态学；（3）运用支序系统学和几何形态学的原理和方法，结合化石形态数据和现生昆虫的分子数据以及地质历史大环境，分析旗腹蜂总科自中生代至今的系统发育关系，探寻其起源和早期演化问题。本项目如能实施，必将为旗腹蜂总科昆虫化石类群的物种鉴定和分类体系的建立提供翔实的对比资料，为确立旗腹蜂总科早期演化历史提供直接证据。

Evanioidea is an important superfamily of Hymenoptera, appeared during the Jurassic radiation, which includes both extinct and extant taxa of it. This research will focus on the Mesozoic Evanioidea from China and Myanmar, with a view to the leading edge of scientific research: (1) to identify the Mesozoic Evanioidea fossils from China and Myanmar, and revise the controversial taxa; (2) to investigate the evolution and functional morphology of important structures (e.g. wasp-waist structures); (3) to further analyze the phylogeny of fossil Evanioidea through phylogenetic and geometric morphometric principle and methods, and combine the extinct morphological characters and extant DNA data to explore the origin and early evolution of Evanioidea. If this project can be put into practice, it will provide integrated and accurate data for identifying fossil Evanioidea, and provide direct evidence to elucidate its early evolution.
