Abstract A new genus and two new species of Dipteromantispidae, an extinct raptorial family of Mantispoidea, are described from mid-Cretaceous (lowermost Cenomanian) Myanmar amber. The forewing of Paradipteromantispa polyneura gen. et sp. nov. possesses trichosors distally, bifurcate humeral veinlet, 1ma-mp connecting RP + MA and MP1, which are distinctive but probably plesiomorphic character states in Dipteromantispidae. The new genus also shares some characters with Dipteromantispa brevisubcosta Makarkin, Yang & Ren, 2013, i.e. the large body size, the medially dilated forewing costal space, and the forewing 1ma-mp distad the first branching point of MP. Kurtodipteromantispa xiai sp. nov. is separated from K. zhuodei Li & Liu, 2020 by the absence of forewing rp-ma and 2ma-mp, and the male genitalia with posterolaterally protruding tergum 9. Based on new materials with well-preserved forelegs, some fine structures on foreleg previously unknown in dipteromantispids are reported. Our finding provides new morphological evidence for understanding the placement of Dipteromantispidae in Mantispoidea.

来自中白垩世缅甸琥珀的新双翅目（昆虫纲：神经翅目：双翅目）

摘要 描述了白垩纪中期（最底层的森诺曼阶）缅甸琥珀中的一个新属和两个新种，即双翅目螳螂亚目已灭绝的猛禽科。Paradipteromantispa polyneura gen 的前翅。等 sp. 十一月 具有远端毛体，分叉肱静脉，1ma-mp 连接 RP + MA 和 MP1，这是 Dipteromantispidae 中独特但可能是拟形的特征状态。该新属与 Dipteromantispa brevisubcosta Makarkin, Yang & Ren, 2013 也有一些共同特征，即体型大，前翅肋间隙向内扩张，前翅 1ma-mp 远离 MP 的第一个分支点。Kurtodipteromantispa xiai sp. 十一月 由于没有前翅 rp-ma 和 2ma-mp，与 K. zhuodei Li & Liu, 2020 分开，和雄性生殖器具有后外侧突出的tergum 9. 基于前肢保存完好的新材料，报告了一些以前在双翅目龙类中未知的前肢精细结构。我们的发现为理解双翅目螳螂科中的位置提供了新的形态学证据。
