N2 - The Issidae are highly diverse in terms of morphology and species richness. Despite recent efforts, the internal phylogeny and classification of this planthopper family remain controversial. Here, we present a phylogeny of the family inferred with Bayesian and Maximum Likelihood analyses of a nine-gene molecular dataset (4702 bp) and morphological data (35 characters) across a broad sample of taxa (99 terminals). Based on these results, we verify the taxonomic status of the issid subfamilies, tribes and generic complexes. Results revealed a well-supported basal dichotomy of the family into two clades, corresponding to the subfamilies Issinae and Hysteropterinae. Within Issinae, the tribes Issini, Thioniini, Sarimini, Hemisphaeriini, Parahiraciini and Kodaianellini were recovered with high support. Four strongly statistically supported clades were revealed within the subfamily Hysteropterinae, but we refrain from taxonomic decisions in the absence of morphological characters to diagnose the clades A–C. Interestingly, the obtained results are in good agreement with L. Melichar's view on Issidae classification suggested more than a century ago. Our results challenge an early Cretaceous origin of the Issidae and the basal split of the family between Neotropical taxa (Thioniini) and the remaining issids.
