GENUS: Hylobates

 

The hylobates are the most populous of the gibbon genera.  They all share a diploid chromosome number of 44 and often have a white ring around their face.

 

The hylobates inhabit the south east Asian islands of Borneo, Java and Sumatra, as well as mainland Asia as far north as southernmost China.

 

Their are six species within the hylobate genus which are detailed below.

 

The lar gibbon has notably slim, long and sharp canine teeth.  This gibbon can be found on the Malay peninsula and the island of Sumatra.

 

The agile gibbon generally has a redness to its fur colour (apart from their white brows), and can also be found on the Malay peninsula and Sumatra.  However, some are also resident to parts of the island of Borneo.

 

Muller's bornean gibbon can be found in different areas of Borneo to the agile gibbon.  The female individuals do not have differing fur colour to the males, and the tops of their heads remain notably black.

 

The silvery gibbon lives on the island of Java and display a bluish tint in their fur colour.

 

The pileated gibbon are generally black furred, but the females are much lighter in colour.  They are only found in mainland Asia within Thailand, Cambodia and Laos.

 

Kloss's gibbon lives in the trees of the Mentawai Islands.

 

It is strongly argued that a seventh species exists called hylobates albibarbis, however it is not completely agreed and this gibbon, known as the bornean white-bearded gibbon, has species status in its own right.  It is listed here as a subspecies of hylobates agilis, the agile gibbon.
