摘要

在白垩纪中期的缅甸琥珀中发现了多种多样的多面体甲虫，但bupresdae的化石记录相对较少。琥珀中白垩纪的buzdids具有精致的形态细节，对了解特征演化和现存亚科的起源和多样化具有宝贵的价值。在这里，我们报告了一种神秘的宝石甲虫，dicyorachys callidictyus Li, Volkovitsh & Cai gen. et spnov .，基于一个埋藏在缅甸北部白垩纪中期琥珀中的保存完好的标本。dicyorachys不寻常的性状组合与任何已知的bu威信亚科都不一致，因此暂定为bu威信科incertae sedis。•关键

Dictyorachys gen. nov., an enigmatic genus of jewel beetles from mid-Cretaceous amber of northern Myanmar (Coleoptera: Buprestidae)

The midCretaceous Burmese amber has yielded a wide diversity of polyphagan beetles, but the fossil record of Buprestidae is comparatively sparse. Cretaceous buprestids in amber with exquisite morphological details are invaluable for understanding character evolution and the origin and diversification of extant subfamilies. Here we report an enigmatic jewel beetle, Dictyorachys callidictyus Li, Volkovitsh & Cai gen. et sp. nov., based on a well preserved specimen entombed in midCretaceous amber from northern Myanmar. The unusual character combination of Dictyorachys is not consistent with any of the known buprestid subfamilies, which is therefore tentatively classified as Buprestidae incertae sedis . • Key
