We describe a new genus and species of Histeridae from Upper Cretaceous Burmese amber, Caterino & Maddison, This species represents the third known Cretaceous histerid, which, like the others, is highly distinct and cannot easily be placed to subfamily. It exhibits prosternal characters in common with Saprininae, but other characters appear inconsistent with this possibility. The abdominal venter is strongly concave, and the hind legs are enlarged and modified for grasping. We hypothesize that this represents the earliest example in Histeridae of modifications for phoresy on social insects.
我们描述了一种来自上白垩统缅甸琥珀的埋葬虫科新属新种，卡特里诺与麦迪逊。该物种是已知的第三种白垩纪埋葬虫，与其他物种一样，具有高度独特性，难以轻易归入亚科。它具有与隐翅虫亚科共有的前胸特征，但其他特征似乎与此可能性不一致。腹部腹面强烈凹陷，后腿增大并经过改造以用于抓握。我们推测，这代表了埋葬虫科中最早出现的对社会性昆虫进行携播的形态改变实例。
