Abstract: The phylogeny of 19 genera of Deltocephalinae leafhoppers was analyzed based on 50 adult morphological characters combined with nucleotide sequences of the mitochondrial 16S rDNA and nuclear 28S D2 rDNA genes. One species of Typhlocybinae was included as outgroup. Parsimonian, distance and Bayesian methods were used to estimate the phylogenetic relationships. The topology of the phylogenetic trees generated with different methods was quite similar. We partially resolved the morphologically defined tribes and the relationships among 19 genera of Deltocephalinae. The genus Macrosteles was well supported to occupy a basal position in the study, so the most primary tribe in Deltocephalinae might be Macrostelini. The phylogenetic analysis trees put all genera of Deltocephalini but Nakaharanus onto a single lineage. The genus Balclutha, corresponding to the tribe Balcluthini, remains unsolved in our analyses. The Euscelini might be a polyphyletic group in the analysis. Analytical result recovered Athysanini and Paralimnini as monophyletic clades. The clade Phlogotettix and Scaphoideus-Nakaharanus was constantly resolved using different methods. We suggested that Scaphoideus, Nakaharanus and Phlogotettix should be included in or into Scaphoideini. But the results resolved poorly the taxonomic status of Xestocephalini overall.
