锹甲属Lucanus Scopoli是锹甲科昆虫的最典型代表。其形态复杂、行为特殊、分布广泛、亚种分化普遍，是研究物种形成与分化的良好素材，且在北半球跨欧亚—美洲大陆间断分布，是研究昆虫地理格局演化的理想模型。本项目以该属为研究对象，从其在全球尺度下的现有地理格局入手，充分利用其在中国区域的丰富物种资源，整合分析形态、分子、地理、化石、古今地质、气候变迁等多源数据，重建其系统发育，以探明该属种间及种下的亲缘关系，揭示其遗传变异、谱系分化及物种形成机制，阐释其现有间断地理格局的演化机理。相关结果不仅将切实解决该属的疑难分类问题，也将为全面认识甲虫的多样性形成、理解北半球甲虫区系的时空演化格局提供更多科学参考，并为开展这类观赏昆虫的生态保育提供必要的基础数据。

Lucanus Scopoli is the most recognized stag beetles as the type genus of Lucanidae. Members of this genus have sophisticated variation, amazing sexual selection behavior, world-wide distribution and numerous subspecies differentiation. Thanks to the traits, these beetles are perfect examples for discovering speciation mechanism. Also, they distributed disjunctly between the Eurasia and American continent. So Lucanus could be an ideal model for biogeographic study. In this project, we selected this genus as subjects to reveal their speciation mechanism and explain why they are presented the current biogeographical pattern. Mult-genes are sequenced for carrying out the phylogeny work. An integrated approach is used to analyze the morphological, molecular, fossil, historic geography, geology and climate data comprehensively. Our aim is to clarify the problematic species group, to explain the speciation mechanisms, to deeply explore the evolutionary history of beetles in the Northern Hemisphere, and to provide useful data for these popular beetles’ conservation.
