Two new bethylid wasps from Cenomanian Burmese amber, one tentatively placed in †Protopristocerinae: Cretapristocera longiscapa gen. & sp. nov. and one in †Holopsenellinae: Megalopsenella pouilloni gen. & sp. nov., are described and illustrated here. They provide new data on the Cretaceous diversity of the family and extend the Cenomanian Burmese amber records to six species. We discuss their systematic placements and provide identification keys to species of †Holopsenellinae and †Protopristocerinae to assist future taxonomic studies. We phylogenetically analyse Bethylidae, adding several fossil taxa to a recent study, suggesting a new hypothesis for the relationships between the different subfamilies. We also address the distribution and underestimated diversity of the family during the Cretaceous and the evolution of the venation of their wings. Finally, we discuss the possible misplacement of the families Plumariidae and †Falsiformicidae.

新的缅甸琥珀化石阐明了甲壳动物黄蜂的进化（膜翅目：Chrysidoidea）

两种新的来自切诺曼尼亚缅甸琥珀的黄蜂黄蜂，其中一种暂定放置在†Protopristocerinae中：Cretapristocera longiscapa gen。＆sp。十一月 †Holopsenellinae中的一个：Megalopsenella pouilloni gen。＆sp。十一月在此进行描述和说明。他们提供了有关该家族白垩纪多样性的新数据，并将塞诺曼尼亚缅甸人的琥珀记录扩展到六个物种。我们讨论了它们的系统放置，并提供了Ho科和and科的物种的识别钥匙，以协助将来的分类学研究。我们在系统发育上分析了乙虫科，在最近的研究中增加了几种化石类群，为不同亚科之间的关系提出了新的假设。我们还讨论了白垩纪时期家庭的分布和低估的多样性以及其翅膀的脉络的演变。最后，我们讨论了P科和科的可能错位。
