To ascertain the validity of this claim and the taxonomic status of these gibbons, we collected twenty-eight samples (faecal, blood and tissue) from various populations of H. hoolock and the alleged Indian H. leuconedys (HL-I). Using DNA isolated from these samples, phylogenetic trees were constructed using D-loop and COI markers. Genetic analysis showed that there are no individuals of H. leuconedys or any separate sub-species found in India, especially between these rivers, and all individuals are part of Hoolock hoolock population. We also performed whole mitochondrial analysis which showed a new topology of gibbon divergence where Hoolock is the first genus to split, ahead of all the three other genera. Our estimates put gibbon divergence in the four genera to have occurred 5.95 mya, and the split between H. hoolock and H. leuconedys 1.06 mya. The finding would be helpful for both in situ and ex situ management of these populations of gibbons. } }
