The sting of the Aculeata or stinging wasps is a modified ovipositor; its function (killing or paralyzing prey, defense against predators) and the associated anatomical changes are apomorphic for Aculeata. The change in the purpose of the ovipositor/sting from being primarily an egg laying device to being primarily a weapon has resulted in modification of its handling that is supported by specific morphological adaptations. Here, we focus on the sheaths of the sting (3rd valvulae = gonoplacs) in
