FIGURE 8. Ultrametric time tree obtained from Analysis 5 in Flightless Notaris (Coleoptera: Curculionidae: Brachycerinae: Erirhinini) in Southwest China: monophyly, mtDNA phylogeography and evolution of habitat associations

FIGURE 8. Ultrametric time tree obtained from Analysis 5 by using BEAST software to date evolutionary events of the Notaris + Tournotaris clade. Numbers at nodes and on the scale below are million years before present. Node bars represent 95% confidence interval of the age estimate. Alternating snowflake and sun symbols denote Pleistocene climatic fluctuations.
