Occurrence of the ground beetle tribe Nebriini in the Baltic amber forest is confirmed. The nebriine taxon Archaeonebria inexspectata gen. n., sp. n., is described and imaged based on four fossil specimens preserved in the Eocene Baltic amber using light microscopy and X-ray micro-computed tomography. The new taxon shares likely synapomorphies with the amphipacific genus Nippononebria and is therefore proposed as its sister group. The occurrence of Archaeonebria in the Baltic amber forests supports previous assumptions that these forests grew under temperate, at least warm-temperate, climatic conditions.
已证实步甲族 Nebriini 在波罗的海琥珀森林中的存在。基于保存在始新世波罗的海琥珀中的四个化石标本，利用光学显微镜和 X 射线显微计算机断层扫描技术，对星云步甲类分类单元 Archaeonebria inexspectata 进行了描述并成像，该分类单元为新属新种。新分类单元可能与泛太平洋属 Nippononebria 具有共同衍征，因此被提议作为其姐妹群。Archaeonebria 在波罗的海琥珀森林中的出现支持了此前的假设，即这些森林生长在温带，至少是暖温带的气候条件下。
