Theraphosa are pretty obvious once you know what to look for, males have a black triangular patch of hairs between the first pair of book lungs (which would also be situated much closer together).

Yeah, definitely female, the dark triangular patch seen on males is visible quite early on (around 3" give or take IIRC) and gets more obvious as they put on size, if you google "Theraphosa stirmi male ventral" or check the link below then you'll see what I mean.
