A new species of Berothidae, sp. nov., is described and illustrated from mid-Cretaceous (lowest Cenomanian) Myanmar amber. It is easily distinguished from other species of Berothidae by the configuration of the wing venation including: forewing with distinct areas of infuscation surrounding cross-veins and vein forks, all cross-veins simple prior to ScP-RA fusion, presence of two cross-veins ra-rp; absence of inner or outer graduate series of cross-veins; RP with three branches; and absence of ma-mp cross-veins and cua-cup cross-veins; while hind wing has cross-vein 1r-m absent. The previous diagnoses of Grimaldi, 2000 and Grimaldi, 2000 are quite unclear because some characters occur mosaically in both genera. In order to solve this problem and distinguish from other species in the family, a new key to species of Berothidae from Myanmar amber has been provided and the diagnoses of and have been revised.
描述并图示了一种来自缅甸白垩纪中期（最低赛诺曼阶）琥珀的新扁翅蚁蛉科物种，新物种。它通过翅脉结构很容易与扁翅蚁蛉科的其他物种区分开来，包括：前翅在横脉和脉叉周围有明显的变暗区域，在ScP-RA融合之前所有横脉简单，存在两条横脉ra-rp；没有内部或外部渐变系列的横脉；RP有三个分支；并且没有ma-mp横脉和cua-cup横脉；而后翅没有横脉1r-m。格里马尔迪2000年和格里马尔迪2000年之前的诊断相当不明确，因为有些特征在两个属中呈镶嵌式出现。为了解决这个问题并将其与该科的其他物种区分开来，提供了一个来自缅甸琥珀的扁翅蚁蛉科物种新检索表，并对格里马尔迪属和相关属的诊断进行了修订。
