Thorny lacewings (Rhachiberothidae) are currently distributed only within Africa, whereas they are prevalent in the fossil record of various Cretaceous ambers across the Northern Hemisphere, with a handful of the fossil records from some Eocene European ambers. Four rhachiberothid species in four extinct genera are known from the mid-Cretaceous amber of northern Myanmar. Here, we report further examples of the remarkable palaeodiversity of this group from the same amber deposit, adding the four new fossil genera and seven new species: Acanthoberotha cuspis gen. et sp. nov., Astioberotha falcipes gen. et sp. nov., Stygioberotha siculifera gen. et sp. nov., Uranoberotha chariessa gen. et sp. nov., Creagroparaberotha cuneata sp. nov., Micromantispa galeata sp. nov. and M. spicata sp. nov. Based on a series of well-preserved specimens, we discuss the fine details of the raptorial forelegs and genital segments, which may be important for elucidating the phylogenetic relationships among genera. Our findings reveal an unexpectedly diverse assemblage of thorny lacewings in the Cretaceous System, highlighting the morphologically diverse rhachiberothids in Burmese amber. The discovery of seven additional rhachiberothid species in Myanmar amber suggests the potential for much higher diversity and abundance of the Cretaceous rhachiberothids than previously documented. Furthermore, morphological variation in the raptorial forelegs was found to be extremely diverse among the Burmese amber paraberothines, especially in terms of the size, number and shape of spines (or spine-like setae) on the inner edges of protibia, and the morphological structure of the probasitarsus.

棘轮草lace（Rhachiberothidae）目前仅分布于非洲内部，而在北半球的各种白垩纪琥珀化石记录中也很普遍，其中一些始新世的欧洲琥珀化石记录也很普遍。从缅甸北部的白垩纪中期琥珀中，已知四个灭绝属中的四个横纹梭菌物种。在这里，我们报告了来自同一琥珀矿床的该群体显着的古生物多样性的更多例子，并增加了四个新的化石属和七个新的物种：Acanthoberotha cuspis gen。等。11月，Astioberotha falcipes gen。等。十一月，Stygioberotha siculifera gen。等。十一月，Uranoberotha chariessa gen。等。十一月Creagroparaberotha cuneata sp。十一月，Micromantispa galeata sp.。十一月 和中号。穗状花序sp。十一月 基于一系列保存完好的标本，我们讨论了猛禽前肢和生殖器官的精细细节，这对于阐明属间的系统发育关系可能很重要。我们的发现揭示了白垩纪系统中棘手的lace虫的出乎意料的不同组合，突显了缅甸琥珀中形态多样的横纹梭菌。在缅甸琥珀色中发现的另外7种横纹梭菌物种表明，白垩纪横纹梭菌的多样性和丰度可能比以前记录的更高。此外，在缅甸琥珀色小ber鱼草中，猛禽前肢的形态变异极为不同，尤其是在pro胫骨内侧边缘的棘突（或脊柱状刚毛）的大小，数量和形状方面，
