享誉全球的中侏罗世燕辽生物群和早白垩世热河生物群是典型的中生代特异埋藏生物群，产出了大量保存精美的昆虫化石。中生代昆虫化石为研究昆虫的早期演化、生物地理学和行为学等提供了重要材料。隐翅虫科隶属于鞘翅目，目前是动物界中最大的一个科。隐翅虫科是一个古老的甲虫类群，在中生代较为繁盛。燕辽生物群和热河生物群都产出了大批隐翅虫化石标本。然而我国中生代隐翅虫的研究程度还不高，重要科学意义还有待发掘，因此两个生物群中隐翅虫的对比研究亟待开展。在现有的研究基础上，综合多种研究手段，将化石与现代昆虫证据相结合，对隐翅虫化石进行分类系统学研究，并探讨某些类群生物地理学演化规律。通过对某些类群细节特征的深入研究，揭示其行为学特征和与周围环境的协同演化关系。最后通过对两个生物群中隐翅虫组合特征的对比分析，以及与中、新生代其他生物群中隐翅虫组成的对比研究，推断隐翅虫科这一超大类群在长期地质历史中自然历史演化过程。

The famous Middle Jurassic Yanliao biota and Early Cretaceous Jehol biota are typical Mesozoic terrestrial exceptional faunas, which have yielded a huge number of beautifully preserved fossil insects. Mesozoic insects can provide significant information about the early evolution, biogeography and behavior of modern insects. Staphylinidae (Coleoptera) is currently the largest group of animal kingdom. It is also an ancient group that thrived in the Mesozoic. The Yanliao and Jehol biotas have yielded numerous fossil staphylinids, but most of them remain to be studied and more significant implications to be revealed. A comparative study of staphylinids from those biotas is badly needed. Based on achieved progress, a combination of several techniques, and a comparison between extinct and extant faunas, fossil staphylinids would be systematically studied, and their biogeographic implications are discussed. The co-evolutionary relationships of certain staphylinids and environment could be revealed by detailed studies of fine structures of these fossils. Based on the staphylinid assemblages of both biotas, plus fossils from other Mesozoic and Cenozoic biotas, the natural history of Staphylinidae in the long-term geological time could be refined.
