Systematic placement of the Norfolk Island psyllid fauna (native taxa in black bold, adventive taxa in red) determined using a maximum likelihood backbone constraint analysis with the mitogenome data from Percy et al. (2018). The two annotated genomes for the endemic species, Acizzia aliceae Percy & Martoni, sp. nov. and Pseudophacopteron aewagriini Percy & Martoni, sp. nov. are illustrated as well as more detailed clade placement for Acizzia spp. (A – Australia, P – Pacific, A-P – Austro-Pacific). Two taxa indicated by [? in grey] are referred to as Glycaspis sp. and Trioza sp. in Maynard et al. (2018) and are considered here to refer to Glycaspis granulata and Powellia vitreoradiata, respectively (see Discussion).
