Wied's Marmoset (Callithrix kuhlii)

This seems to be a quite rare species in captivity, with only 2 other holdings according to Zootierliste, both in North America. I hope it's not just a misidentification.

This is a black-tufted marmoset, so yes a misidentification

Thanks for the comment!
If possible, can you tell me how to distinguish these species from this photo?

@Toki Compare it with this picture:

Wied's marmoset - Wikipedia

There is something of a dark ring around the eyes and the cheeks and the overall pattern just don't fit. A Wied's marmoset would also have less bushy ears. But beware when looking at google images, plenty of misidentifications there too...

@lintworm
Thanks for the information!
It's really helpful!
Yes, this animal does capture those patterns.

And it also looks like there are misidentified images online too...
