(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 [24]). 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 [24] and black dots on nodes indicate Bayesian posterior probabilities of > 0.96.
