The generic data matrix and database of adult morphology of Tenthredinoidea were set up. The polarization of each morphologic character was concluded based on the evolutionary morphology, the inner group comparision and fossils analysis. The generic cladogram of Tenthredinoidea was calculated by PC586 computer using Hennig86 program. A new classification system for Tenthredinoidea was proposed based on the analysis of the cladogram. The tribal cladistic biogeography of the superfamily was analyzed using Diva program.
