Figure 1 in Molecular phylogeny and divergence times of Hormaphidinae (Hemiptera: Aphididae) indicate Late Cretaceous tribal diversification
Figure 1. Phylogeny of Hormaphidinae based on nuclear EF-1a sequences. The tree obtained from Bayesian analysis is shown. Numbers above the branches are bootstrap values (> 50) from maximum-parsimony/maximum-likelihood analyses, and the Bayesian posterior probabilities (> 0.90) are shown below the branches. Species including more than one sample are represented by species names with voucher numbers.
