Mexico 2013, from the instagram of Joel Fridman - one of two brothers credited for this production just as 'acrobat'. Joel is the one on the far right - Natan Fridman is presumably the one on the left, Mistoffelees and Munkustrap look to me like first cast Orville Alvarado and Marco Salazar, though I'm not confident enough with that identification to put this photo on their pages.

Judging by this photo, and by Lisette Garzón's comment on about them being evil, these 'acrobats' were henchcats - or doubled as henchcats. The fact that they're only credited as 'acrobat' suggests perhaps that they weren't onstage much? and they don't appear in much footage of the production. Judging by glimpses in backstage footage - and by the dramatic nature of the makeup, which would have taken a while to apply or to remove/disguise - they wore this makeup for all or most of the show. So even if they did appear onstage at other times, they presumably didn't participate much in the ensemble numbers - maybe just for stunts like the trapeze? Will edit this once I've combed through more footage looking for them specifically.
