I forgot to list the number of ZTL zoos slow lorises
Pygmy slow lorises (36 ZTL zoos)
Greater slow loris (Nycticebus coucang) (10 ZTL zoos)

Have these been kept with lemurs by other institutions before ?
Several zoos have lemurs and slow lorises

Yes, but with my question I specifically meant institutions which keep these species within the same enclosure like at the Duke lemur center.
It doesn't strike me that this would be a common arrangement for zoos given that the loris is venomous.

ZTL lists species but doesn't note which species share enclosures. I've never seen slow lorises share enclosures with lemurs.

Yes, it strikes me as an odd choice but a zoochatter who had visited Duke and taken the picture stated that the aye-aye were elderly animals and the enclosure large.
Only two zoos keep N. coucang, Berlin Zoo and Prague. There are 9 institutions listed on ZTL with slow loris sensu lato, meaning their animals are either hybrids or of unidentified species. I'd assume the latter is the case, which is strange since one would imagine it wouldn't be overly difficult to figure out which taxa they are.
Additionally, 6 zoos and I think one private collection keeps Bengal Slow Loris, N. bengalensis.
For lorises in general, about 11 zoos keep Grey Slender Loris.

The first ruffed lemur to be born in the UK was a red ruffed lemur X black & white ruffed lemur hybrid.
London Zoo acquired a female black & white ruffed lemur from David Attenborough’s “Zoo Quest to Madagascar” expedition in 1960; nine years later, in 1969, the Jardin des Plantes Menagerie (Paris) loaned a male red ruffed lemur to London Zoo and this pair produced a hybrid youngster in 1972.

What about N. javanicus ?
It is far more endangered than either N.coucang or N.bengalensis and would surely benefit from ex-situ management (there must be quite a lot of reproductively viable individuals in rescue centres in their native range too).
Interesting info , thanks for sharing Tim! I never knew this.
Thanks, Thylo
I noted that both pages listed N. coucang with Berlin Zoo and Prague Zoo on 1 page and 9 zoos (including Berlin Zoo again) on another. I realise that there have been problems with slow loris classification; when I was a boy, there was just 1 species. Many years ago, I went to a talk at London Zoo, where a zookeeper showed a slide of a captive slow loris with a long tail. I don't know if the 9 zoos listed as 'N coucang' genuinely keep this species. I have seen species that are not listed on ZTL and many animals listed in 'Former Holdings' were classified using the taxonomy at the time.

According to ZTL, there are no Javan slow lorises in European zoos. The species was kept in 5 ZTL zoos: ZootierlisteHomepage

Yes, DNA analysis seems to point to there being many more loris species than previously thought just as we have identified with mouse lemurs and galagos (but if I remember correctly with the latter this was identified through analysis of vocalizations in the 90's rather than DNA analysis specifically).

This species would strike me as the most suitable for ex-situ management but I know it is hardly easy when it comes to slow loris and they are quite a difficult group in terms of adaption to captivity (still husbandry is improving and being informed by research though).
I think the Prague animals were actually imported as Javan but turned out to be proper Sunda. The Berlin animals are a more recent acquisition, and I assume were imported in an attempt to maybe start a new program alongside Prague's pair (though those have never bred afaik). I'm not too familiar with the history of the Bengal program in Europe, however I do know Augsburg's original pair were brought in as coucang and later reidentified. The rest of the population could have come in as a result of RSCC and/or Moscow imports looking at ZTL. I'd imagine the three (four) loris species currently being worked with have more or less been stuck to by European zoos simply due to them already being established and therefore a mass import of founders does not need to take place, though I agree that this probably wouldn't be overly difficult to accomplish.

As far as potto go, Europe is down to four zoos but I don't think any are breeding them.
I think the US itself is down to 3-5 zoos with the species as well...

Great shame in my opinion (I really love this species and would like to see it in more European / North American / Australian zoos) but then again it is currently only "near threatened".
I am sure that this current status of the potto will worsen in the future though with climate change, bushmeat hunting and deforestation and this may perhaps lead to more zoos keeping them.
In contrast many species of the Loris and Nyticebus genus are considerably more endangered.

In Japan Ueno Zoo has the Javan Slow Loris.

I imagine that these arrived there as rescues from the pet trade (I know that trafficking of the slow loris to Japan for sale as "pets" is quite an issue) ?
Simon Bearder (https://www.researchgate.net/profile/Simon_Bearder) used galago calls to identify new species. He presented the type specimen of the Rondo galago to London Zoo.
