Two new mantid lacewing genera and species, Archaeosymphrasis pennyi gen. et sp. nov. and Habrosymphrasis xiai gen. et sp. nov., are described from mid‐Cretaceous Myanmar amber. Phylogenetic analysis recovered the new genera as stem‐group Symphrasinae, sister to the rest of the subfamily. These represent the oldest fossil record of the subfamily Symphrasinae (Neuroptera, Mantispidae) and illuminate the evolutionary history of Symphrasinae, as well as providing insights into the group's historical biogeography. They also provide new evidence for divergence time estimates of extant mantispid subfamilies.

Symphrasinae的干群化石为螳螂科（Insecta，Neuroptera）的早期进化提供了启示

两种新的螳螂lace属和种，古细菌彭妮属。等。十一月 和Habrosymphrasis xiai gen。等。11月，描述于白垩纪中期的缅甸琥珀。系统发育分析将新属恢复为新亚属，是其余亚科的姐妹。这些代表了Symphrasinae亚科（Neuroptera，Mantispidae）的最古老化石记录，阐明了Symphrasinae的进化历史，并提供了对该群体历史生物地理学的见识。他们还为现存的螳螂亚科的发散时间估计提供了新的证据。
