The Zoochat Photographic Guide to Old World Primates

ZTL lists a few pure Chlorocebus as non-(sub)specific, they like to just lump entire populations with only a handful of pure holders as sensu lato as oppose to trying to actually work it out..

Thanks, that is a brilliant photo!

I have just gone through and compiled a list of the species (as recognised in this thread) which do not yet have photos in the Zoochat galleries. There are just over 40 species unrepresented, as listed below. (For comparative purposes, there are about 190 species total in the thread of which about 150 are represented by photos, which is a fantastic percentage). [I will keep this post updated whenever "new" species are added to the galleries - last update: 30 August 2025]

There are 154 species represented by photos (out of about 190 total species in the thread - the species which are currently unrepresented by photos are in the post immediately before this one). There are currently 263 photos in total in the thread, by 87 members. I will keep this tally updated whenever I add/remove/change photos [last update: 30 August 2025].

Are there bonus points available for being in one of the photos as well?

(You'll have to guess which.)
 
This doesn't change the stats for the thread really, but a genetic study was just published wherein the three subspecies of Banded Leaf Monkey Presbytis femoralis were all elevated to full species: Faecal DNA to the rescue: Shotgun sequencing of non-invasive samples reveals two subspecies of Southeast Asian primates to be Critically Endangered species | Scientific Reports

The three species are the Raffles' Leaf Monkey P. femoralis, the Robinson's Leaf Monkey P. robinsoni, and the Sumatran Banded Leaf Monkey P. percura. Of the three species, only one was represented by a photo anyway (P. robinsoni) so the numbers haven't changed.
 
There has been another recent primate split, where the Phayre's Langur Trachypithecus phayrei has become three species. The paper can be read here: Mitogenomic phylogeny of the Asian colobine genus <i>Trachypithecus</i> with special focus on <i>Trachypithecus phayrei</i> (Blyth, 1847) and description of a new species

The western form retains the name T. phayrei; the form in central Burma has been described as a new species, T. popa; and the eastern form (previously the subspecies T. p. shanicus) has been renamed T. melamera.

The only one of these depicted in the galleries is T. melamera, which is a bit annoying because until now every species of Trachypithecus was pictured in the thread.

A photo of one of these three species, the Raffles' Leaf Monkey Presbytis femoralis has recently been added to the gallery, with a photo taken in the wild in Singapore by @Casuarius_casuarius

I neglected to mention an update for this post last year, where a photo of Trachypithecus phayrei had been uploaded by @Junklekitteb from the Bannerghatta Biological Park in India; on page two of the thread in this post: The Zoochat Photographic Guide to Old World Primates

It's not the best photo for showing the species, but it means that the only Trachypithecus not currently represented in the thread is the Popa Langur T. popa from central Burma.

Western Red Colobus Piliocolobus badius
Three subspecies: badius, temminckii, waldronae


The only photos in the Zoochat galleries are of museum specimens.

Just uploaded some photos of subspecies P. b temminckii in the The Gambia Wildlife Gallery ( Western red colobus - Piliocolobus badius temminckii - ZooChat , Western red colobus - Piliocolobus badius temminckii - ZooChat , Western red colobus - Piliocolobus badius temminckii - ZooChat , Western red colobus - Piliocolobus badius temminckii - ZooChat and Western red colobus - Piliocolobus badius temminckii - ZooChat ) so if you want to change the photo of the museum specimen for a photo of a living animal, you can choose yourself.

That's great. I used two of those photos to replace the photo of the taxidermy animal.
 
An amazing new species has been added to the thread, with Myanmar Snub-nosed Monkey Rhinopithecus strykeri by @YuanChang - an event I would never have predicted. This species is probably the one I would have said was the most unlikely Old World primate to ever be represented in the Zoochat galleries (the list of the 50-odd unrepresented species is a few posts up, #144).

The individual is a rescued animal held since 2013 at the Yaojiaping Rescue Station in China. Several excellent photos are in the China Other gallery. The one below is the one I have used in the thread:

I'd have said Piliocolobus waldronae, but it appears you don't recognise that one as a distinct species!

It's a pity that FunkyGibbon left the forum some time ago, as he has photographs of Tapanuli Orangutan - but given the recent discovery that the species occurred in North American (and possibly European) collections into the 1990s there is a decent chance we might be able to unearth a photograph thus.
