Rhachiberothidae, sometimes called thorny lacewings, are a family of winged insects in the order Neuroptera. The family has only 14 extant species in 4 genera found in Sub-Saharan Africa, but has a diverse fossil record extending back to the Early Cretaceous in Lebanon (then part of North Gondwana), Eurasia and North America. Like the closely related Mantispidae members of the group possess raptorial forelegs, which probably only evolved once in the common ancestor of the groups. Long included in the Berothidae (beaded lacewings), they are usually considered a separate family by current authors. Another closely related group are the mantidflies (Mantispidae), and at least some of the probably paraphyletic group of fossil forms collectively called "Mesithonidae" also seem to be quite close.
