My guess is a blondi.
Have she moulted since you have her is it a male or female?
I think males tend to be more slender and leggy, at least I think I have read that somewere in here.
Beautiful T anyway.
With only two species in the genus it appears to me that it should be fairly easy to tell them apart. Furthermore the density of leg setation and the relative robustness of the femora are pretty taxonomic if I may say so ;-)
I said that because there where more opinions about what it is. So apparantly it's not so easy. I feed my theraphosa alot less then most people would. That could be the reason that it looks a bit more slender then normal. But i agree with you about it being a apophysis.
