Dagger Zigrasimeti BARDEN & GRIMALDI，2013通过独特的下颌骨形式，触角scrobe的存在和巨大的块状头骨，很容易在蚁科的总多样性中识别。白垩纪中期缅甸琥珀中的两个物种目前被归于该属，一个是dealate gyne，另一个是worker。在此，我们描述了两个新的种，从缅甸琥珀的基础上工人：Zigrasimelyhoelldoblerisp. n。和tProtozigrasimidae chauli gen.n. sp.n.，它显示了一套与匕首Zigrasimme有关的准形态。我们还举例说明并提供了一个未放置的立面的描述性草图。根据这两个新分类群的新形态特征，我们编制了剑刺叶蜂族属的检索表。匕首Z保存得很好。霍尔多勃勒里种揭示了zigrasimeciine口器的功能形态学。由于匕首蚁和匕首原蚁的口器具有凶猛的功能，我们通俗地称它们为铁娘子蚁。此外，还讨论了中生代蚁科的翅脉和中体型的演化。我们的工作是一个贡献，更好地了解中生代蚁科和文件的多样性，为家庭的繁衍。
dagger Zigrasimecia BARDEN & GRIMALDI, 2013 is easily identified among the total diversity of the Formicidae by the unique form of the mandibles, presence of an antennal scrobe, and the massive, blocky cranium. Two species from mid-Cretaceous Burmese (Myanmar) amber are currently attributed to the genus, one is a dealate gyne and the other a worker. Herein, we describe two new species from Burmese amber based on workers: Zigrasimecia hoelldobleri sp.n. and tProtozigrasimecia chauli gen.n. sp.n., which display a suite of plesiomorphies which are retained relative to dagger Zigrasimecia. We also illustrate and provide a descriptive sketch of an unplaced elate. With the new morphological characters from the two new taxa, we provide a key to the genera of the dagger Zigrasimeciini. The remarkable preservation of dagger Z. hoelldobleri sp.n. sheds considerable light on the functional morphology of zigrasimeciine mouthparts. Due to the ferocious function of the mouthparts of dagger Zigrasimecia and dagger Protozigrasinlecia, we colloquially dub these the iron maiden ants. Furthermore, we discuss wing venation of Mesozoic Formicidae and evolution of mesosomal form. Our work constitutes a contribution to a better understanding of the Mesozoic Formicidae and documents diversity for the phylogeny of the family.
