Palaeoxenus sinensis Chang, Muona & Teräväinen sp. nov. (Coleoptera, Eucnemidae) is described on the basis of a Cretaceous larva found from the Yixian Formation in Huangbanjigou, Liaoning Province, China. The only previously known member of this clade is a southern Californian endemic, Dohrn's elegant eucnemid beetle (Palaeoxenus dohrni), a species that develops in conifers, especially the incense cedar (Calocedrus decurrens). The new find proves that the highly specialized main eucnemid lineages had evolved 123 Mya, before the main radiation of the angiosperms and probably as an adaptation to development in gymnosperms.
中华古隐翅虫（Palaeoxenus sinensis Chang, Muona & Teräväinen sp. nov.）（鞘翅目，隐翅虫科）是根据在中国辽宁省黄半吉沟义县组发现的一只白垩纪幼虫描述的。该分支此前唯一已知的成员是南加利福尼亚特有的多恩优雅隐翅虫（Palaeoxenus dohrni），这是一种在针叶树，尤其是香脂冷杉（Calocedrus decurrens）中发育的物种。这一新发现证明，高度特化的主要隐翅虫谱系在被子植物主要辐射之前的1.23亿年前就已经进化，可能是对裸子植物发育的一种适应。
