Figure 3: Dated phylogenetic tree of Metachirus based on cytochrome b gene (Cytb). Colours: red = Guyana Shield, Metachirus nudicaudatus; yellow = Xingu/Tocantins, Metachirus aritanai new species; dark green = Central America and pink = Central/Northwestern Amazonia; orange = Southeastern Amazonia; blue = Eastern Amazonia/Teles Pires River; and light green = Atlantic Forest, Metachirus myosuros; (black = outgroup). Values above nodes represent divergence time in million years and values below nodes the posterior probability. Node bars represent the highest posterior density (HPD) interval of 95%. Time scale in million years.
