Molecular divergence of Arboridia COI gene. The estimated marginal density function is shown on each node. The clock has been calibrated at node a (minimum 44.4 MYA) and b (17.5–90 MYA). Values of x-axis are MYA. Along the x-axis (periods and epochs): P = Pleistocene, Pli = Pliocene, Q = Quaternary.
