A remarkable new genus of Mantispidae (Insecta, Neuroptera) from Cretaceous amber of Myanmar and its implications on raptorial foreleg evolution in Mantispidae

Micromantispa cristata gen. et sp. nov. is described from the Cretaceous amber of Myanmar. This is the smallest mantispid. Its raptorial forelegs are relatively slender, bearing dense spines and setae on femora and tibia. The first tarsal segment has two long spines on the dorsal apical, which is newly observed in the family. The morphological diversity of the prothorax and raptorial forelegs in Mantispidae through the geological history are discussed.
