Depends on what you mean by place.Which of the various setting specific races do you think deserve a place in 5e?
I also believe that they exist in at least two settings already, yes? FR and Dark Sun.I wish I could have voted for the ThriKreen more than once. There is not other insect based race and they are just so darn cool thematically. But thats just personnel biase, I can imagine saying that for most settings they are inappropriate.
Thri-Kreen are pretty neat too, groups I've been in have used the stats but labelled them Aspis for non Dark Sun games. Roughly the same bug confused by the fleshy people and their waysI wish I could have voted for the ThriKreen more than once.
