so what is she then?

That's a way of looking at things I hadn't considered. I guess to me, a beastman is defined as a sentient species whose physical traits more resemble animals than hyur.

But then, who knows what those goblins look like under their masks!

You only have to see Miqo'te to see that half beast half human is a little wrong to describe beast tribes, even more if Yugiri is indeed an half dragon or lizard race. And you don't have to looks like a beast to be called a beast or a monster.

post limit so :
EDIT FOR BELOW :

I don't see any representative of Yugiri's race living around Limsa, Ul'dah or Gridania, except Yugiri herself (who's a refugee).
There's also moogles in every cities.
And the reason the Amal'jaa got kicked out is mostly because when the whole Empire/Primal summoning started, it started to get a little... tense between them and the other. Before that, they were accepted just like Goblins and Qiqirns.

What I mean to say in the end is, the difference between a beasttribe and one of the 5 races isn't simply "they are accepted in city-states".

Because Yugiri's race isn't known by the city-states, so it's neither a beast tribe nor a human race. And there is a huge difference between accepted and being part of a city, a little like living someplace but not having the nationality, not being considered as a citizen of this place.
