A new polypore fungus beetle species Allostrophus Hsiao, Ślipiński, Yu, Deng and Pang embedded in Upper Cretaceous Burmese amber (Cenomanian, ca. 99 Ma) is described: A. yangi sp. nov.; this new species can be differentiated from its only congener based on its antennomere 11 and fusiform, elongate body. Morphological characters preserved in the inclusion compared to A. cretaceus Hsiao, Ślipiński, Yu, Deng and Pang provide further data for completing the definition of Allostrophus. This new discovery highlights the species diversity of fungivorous beetles during the Cretaceous period, adding evidence that the formerly hypothesized co-diversification between fungus-feeding coleopterans and their food resources originated in the late Mesozoic Era.

白垩纪中部琥珀色真核生物的分类学注释，并描述了一个新物种（鞘翅目，四足纲）

描述了一种新的多孔真菌甲虫种，分别是上白垩纪缅甸琥珀（Cenomanian，约99 Ma）中埋藏的小同种小s，Ślipiński，Yu，Deng和Pang：A. yangi sp。十一月 这种新物种可以根据其仅有的tentenmere 11和梭形细长体与唯一的同类动物区分开。在列入保存形态特征比较A. cretaceus萧，Ślipiński，玉，邓和庞完成的定义提供进一步的数据Allostrophus。这一新发现突出了白垩纪时期的食性甲虫的物种多样性，并增加了证据表明，以前假设的食用真菌的鞘翅目昆虫及其食物资源之间的共同多样化起源于中生代晚期。
