Popis Jumping plant lice (Hemiptera: Psylloidea) are known for a few deleterious pest species worldwide, yet the phylogeny of the group has been poorly understood until very recently. Here, we reconstruct the higher-level phylogeny for the superfamily Psylloidea based on multilocus DNA sequences, three mitochondrial (COI-tRNAleu-COII, 12S, 16S) and five nuclear (18S, 28S D2, 28S D3, 28S D6–7a, 28S D9–10) gene fragments, using maximum likelihood and Bayesian inference phylogenetic frameworks. Our results are largely congruent with the recent phylogenomic study and partly support prior classification of Psylloidea based mainly on morphology, with the following major exceptions: the family Calophyidae is revealed as polyphyletic, Aphalaridae as paraphyletic with respect to most other taxa of Psylloidea, and Liviidae as paraphyletic with respect to Calophyinae, Psyllidae and Triozidae. Our phylogenetic hypothesis identifies Phacopteronidae and the genus Cecidopsylla Kieffer as the very basal taxa within extant Psylloidea. Sister-group relationships of Rhinocolinae with Togepsyllinae and of Pachypsyllinae with Homotomidae are also suggested. We present specific discussions for each group of interest recovered in our phylogenetic analysis. One nomenclatorial change is proposed: Spanioneura longicauda(Konovalova) comb.n., from Psylla Geoffroy.
