Not much to go on but it has a fairly long tail snaking up the branches above its shoulder. Possibly Macaca fascicularis, Long-tailed macaque.


Equatorial lowland rainforest.

I agree, it does look like another one behind it. The pictures were taken from a boat on the river and I did not take any notes as I was too busy taking photos. I have enlarged the pic and there is indeed so there is another one behind. a hand at the end of a long arm and not a tail. The guide listed several species on that trip and I am fairly sure Pig-tailed was among them.

In blowing up the picture it looks like a joint in the appendage behind it. It looks more like an arm with an elbow. Is it possible there was a second one behind it? if that is indeed a tail, you are right. That rules out the Pig-tail. Interesting, challenging, frustrating :-)

The trouble with that is what appears to be a very long tail draped across the branch behind it.

Malcolm. Yes, that is the same list I come up with now. Out of them the only one that it could possibly be, based solely on the hand/food is the Pig-tailed macaque (Macaca nemestrina). But then I was wrong before :-).

Glad you checked it out Malcolm. I now know a little more about the geography of the area as I checked out the ranges too. I don't find any primates with the hairless white hand/foot as in your picture. Hope you can find something. You'd think a primate that large would be easier to identify, but that's what makes it an interesting challenge.

Some Maroon Langurs have greyish hands, on my pics they look pinkish and the body in shadow looks dark grey while that in sunlight appears pale brown.
The following are the only species I can find recorded from Sabah:
Cephalopachus bancanus Western tarsier common name: Kera hantu
Presbytis hosei Hose's langur
Presbytis rubicunda Maroon langur
Trachypithecus cristatus Silvered langur
Nasalis larvatus Proboscis monkey
Macaca nemestrina Pig-tailed macaque
Hylobates muelleri Müller's Bornean gibbon
Pongo pygmaeus Bornean Orangutan .

Hi Tukup, thanks for your suggestion. I have checked the range of the species you suggested and it does not include the island of Borneo where this one was seen. Sabah is part of East Malaysia which is geographically separated from West Malaysia by the South China Sea. I will check the Borneo species list to see if other similar species are present in Sabah.

I would guess it's a White-handed Gibbon or Lar Gibbon (Hylobates lar). While the color of their coats changes, they all have white hands just like in your picture.
