Abstract

The first fossil monotypic genus of the subfamily Necrophilinae (Coleoptera, Agyrtidae), Palaeonecrophilus buryaticus gen. et sp. nov., is described from a positive and negative imprint found at the Early Cretaceous Khasurty locality in Western Transbaikalia. The beetle is similar to modern Necrophilinae in the presence of notches on the apical antennomeres and the wide and flattened edges of the pronotum. It is distinguished from the modern species by the strong anterior protrusion of the anterior pronotal angles and the oblique orientation of the metanepisterna. Widely spaced anterior coxae with a process between them distinguish the new species from the representatives of the genus Necrophilus. Palaeonecrophilus presumably fed on carrion, like modern Necrophilus and Zeanecrophilus.

下白垩统卡苏蒂地区的一种新的甲壳纲甲虫（鞘翅目，甲壳纲）

摘要

Necrophilinae（鞘翅目，Agyrtidae）亚科的第一个化石单型属，Palaionecrophilus buryaticus属。等。nov。是从在西贝贝卡利亚西部的早白垩世Khasurty地区发现的正面和负面烙印进行描述的。甲虫类似于现代的嗜肾菌科，在顶端的天线突上有缺口，并且前胸膜的宽而平坦的边缘上。它与现代物种的区别在于前胸膜前角的强力前突和后乳突的倾斜方向。间隔较宽的前髋关节与它们之间的过程将新物种与死灵菌属的代表区分开来。Palaeonecrophilus大概以腐肉为食，就像现代的Necrophilus和Zeanecrophilus。
