A single topology for backbone, a published phylogenomics (AHE) tree: Bybee et al. (2021) Phylogeny and classification of Odonata using targeted genomics. Molecular Phylogenetics and Evolution, 160, 107115. Synthesis constructed by constrained backbone (Chesters, 2019, Syst Entom, 45), using multigene alignment of COI from BOLD, and seven markers from NCBI, homologous to those of: Letsch et al. (2016) Not going with the flow: a comprehensive time-calibrated phylogeny of dragonflies (Anisoptera: Odonata: Insecta) provides evidence for the role of lentic habitats on diversification. Mol Ecol, 25, 1340-1353. Synthesis phylogeny comprises 768 species with single outgroup Baetis_tricaudatus. * If used in a publication, please cite Chesters, Ferrari, Lin, Orr, Staab, Zhu (2023) Launching insectphylo.org; a new hub facilitating construction and use of synthesis molecular phylogenies of insects.
