Although reconstruction of the phylogeny of Hemiptera has progressed tremendously over the past two decades, some higher-level relationships remain poorly resolved. Here, we investigated the Hemiptera higher-level relationships using full mitochondrial genome data from 357 ingroup species, representing the most comprehensive sampling yet undertaken for reconstructing the phylogeny of this group. In this study, 92 mitochondrial genomes were newly determined. Various data treatment methods and substitution models were applied to tree reconstructions. Effects of compositional heterogeneity, rate heterogeneity, model adequacy and taxon sampling on support values and topological stability were explored. Phylogenetic analyses (1) confirmed the monophyly of Hemiptera under site-heterogeneous model, (2) placed Sternorrhyncha as sister to all other Hemiptera, (3) recovered Coccoidea as the sister taxon of Aphidoidea, followed successively by Aleyrodoidea and Psylloidea, and (4) indicated that the grouping of Coleorrhyncha and Fulgoromorpha was the result of long-branch attraction effect.
