Jumping plant-lice (Hemiptera: Psylloidea) are known for a few deleterious pest species worldwide, yet the phylogeny of the group has been poorly understood. The goal of researching the Korean Psylloidea is to achieve a total overview of the group. The systematic study relies on three main pillars which are i) the taxonomic review of superfamily Psylloidea in the Korean Peninsula, ii) the correction of taxonomic confusions caused by phenetic plasticity and iii) the molecular phylogeny of Psylloidea to elucidate the higher-level phylogenetic relationships among the families and subfamilies of the superfamily Psylloidea. Discussions of the early diversification and evolution of Psylloidea will be presented together with comments on biogeography and host plant association.
