(A) Neighbor-joining tree of Presbytis taxa based on the acoustic similarity matrix (F values) and (B) their phylogenetic relationships according to mitochondrial sequence data (redrawn from ). In A, colored letters indicate species and numbers corresponding to sampling locations (see Figure 1). In B, branch lengths refer to those obtained from the Bayesian reconstruction in  and black dots on nodes indicate Bayesian posterior probabilities of > 0.96.
