Bought this as a G.rosea from a petshop, but not so sure anymore. Possibly another Grammostola or Brachypelma?
It is around 2cm legspan.
Any ideas?

I am clueless but I would like to say it resembles an baboon spider.

I am quickly going to post another pic of my unknown looks very similar.

I'm even less clued then Meteor, but I agree, the abdomen shape and markings plus all that webbing makes me think old world. Not entirely sure about the dark patch but doesn't look like urticating hair, and I see no tell tale 'mirror patch' .

I would say its definitely not any brachypelma species...

Looks like 3rd or 4th instar Stromatopelma calceatum to me.
