    Abstract

    Evidence of incongruence between mitochondrial and nuclear gene trees is now becoming documented with increasing frequency. Among the Old World monkeys, this discordance has been well demonstrated in the Cercopithecinae, but has not yet been investigated in the Colobinae. The mitochondrial relationships between the colobine genera have recently been clarified and cluster Presbytis and Trachypithecus as sister taxa to the exclusion of Semnopithecus. This is incongruent with previous morphological hypotheses that suggest the latter two are sister taxa, and perhaps even congeneric. In addition to analyzing a previously published 10,896 bp mitochondrial dataset, we sequenced and analyzed a 4297 bp fragment of the X-chromosome in order to test the competing mitochondrial and morphological phylogenetic hypotheses. The results from the mitochondrial dataset again support a Presbytis + Trachypithecus group while the X-chromosomal dataset supported a Semnopithecus + Trachypithecus group. A Shimodaira-Hasegawa test performed on both datasets indicates that the mitochondrial and X-chromosomal trees are significantly better at explaining their respective datasets than alternative topologies (p < 0.05). We suggest that differential lineage sorting or ancient hybridization may be the cause of this strong discordance between the mitochondrial and X-chromosomal markers in these taxa.
