Core gene phylogenies of Pariaconus psyllids. Topological congruence detected among the best approximately-maximum-likelihood trees generated for the insect nuclear genes, Carsonella and entire mitogenome sequences. Branches are shaded by the major Pariaconus species groups ohialoha (blue), minutus (black), and bicoloratus (red) and sample datasets generated here are labeled to the left. An additional published Pariaconus mitogenome (Percy et al. 2018) and outgroup RefSeq mitogenomes from Triozidae psyllids (n = 4) are included in the mitogenome phylogeny. Adjacent to each node statistical support values ≥ 50 from FastTree are shown above and RAxML-ng bootstrap scores are shown below. Inset box shows estimated ages for nodes on the Carsonella phylogeny based on the split between the bicoloratus species group and the others occurring between 3 and 3.5MYA
