One new genus and three new species of Pamphiliidae, gen. et sp. nov., sp. nov., and sp. nov. are described and illustrated. All of them were collected from the Lower Cretaceous Yixian Formation in Duolun County, Inner Mongolia, China. The new genus is established based on the following characters: body surface without punctations; forewing with pterostigma lanceolate and sclerotized around the margins; angle between 1-M and 1-Cu nearly 90°; cell 1mcu long and obviously longer than length of pterostigma. In most cases, the ap-Cu is present, and its length varied. Additionally, we revise the diagnostic characteristics of Juralydinae based on the new specimens. New findings enhance our understanding of the wing venation characteristics of fossil pamphiliids and expand the diversity of Pamphiliidae in the Mesozoic.
描述并图示了叶蜂科的一个新属及三个新物种，即新属、新物种1、新物种2和新物种3。它们均采自中国内蒙古多伦县下白垩统义县组。新属基于以下特征建立：体表无刻点；前翅具披针形翅痣，边缘硬化；1-M与1-Cu之间的夹角近90°；1mcu室长，明显长于翅痣长度。多数情况下，ap-Cu存在，其长度可变。此外，我们根据新标本修订了侏罗叶蜂亚科的鉴别特征。新发现增进了我们对化石叶蜂翅脉特征的理解，并扩大了中生代叶蜂科的多样性。
