Zigrasimeciinae is a subfamily of ants, known from the Cretaceous period, originally named as the tribe Zigrasimeciini within the subfamily Sphecomyrminae by Borysenko, 2017,[1] it was elevated to full subfamily in 2020. It contains three described genera.[2] They are sometimes known as iron-maiden ants in reference to their densely spiked mouthparts, reminiscent of an iron maiden torture device, that were likely used to trap prey.[3]Boltonimecia canadensis was described from CampanianCanadian amber out of Alberta, Canada, while the species of Protozigrasimecia and Zigrasimecia are both exclusively known from CenomanianBurmese amber found in Myanmar.[3]
