The leaf-footed bugs and allies make up the superfamily Coreoidea of the true bug infraorder Pentatomomorpha. There are 5 families presently recognized, but the Coreoidea as a whole are part of a close-knit group with the Lygaeoidea and Pyrrhocoroidea and it is likely that these three superfamilies are paraphyletic to a significant extent; they are therefore in need of revision and redelimitation.
