Further molecular studies, however, suggested they are outside the clade Mecopterida (containing the Diptera and Lepidoptera), but found no strong evidence for affinity with any other extant group.
Porén, posteriores estudos moleculares suxeriron que estaban fóra do clado dos Mecopterida (que contén a Diptera e Lepidoptera), pero non encontraron fortes evidencias de afinidades con ningún outro grupo actual.
