Vietnam Primate Conservation Status Review Part 2: LEAF MONKEYS 22 The genetic distances between the other three taxa are within the range typical for those between species, which has led to the conclusion to separate all three taxa as distinct species (Roos & Nadler, 2001). Phylogenetic tree reconstructions carried out on the data set resolve the relationship among the three taxa with high support. P. nigripes branched off first, followed by cinerea and nemaeus. These relationships fit well with the distribution pattern observed in douc langurs. 95 0.1 100 97 96 99 100 100 99 75 52 90 95 100 100 C. guereza T. obscurus T. phayrei T. crepusculus T. francoisi T. poliocephalus poliocephalus T. poliocephalus leucocephalus T. delacouri T. laotum laotum T. laotum hatinhensis T. auratus T. cristatus T. germaini R. avunculus R. roxellana R. bieti P. nigripes P. nemaeus P. cinerea Fig. 2.3-1. 50%-majority-rule consensus tree for the maximum-likelihood method following a molecular clock. Branch lengths are drawn according to the number of substitutions per position with the bar indicating 0.1 substitutions per site. Numbers in the tree indicate bootstrap values in %.
