@BenWilly I kind of figured that myself but wanted other opinions. She was sold to me as a B.Albo. I didn’t think anything of it until she started to get a bit bigger and more coloring started to show up.
Definitely not an albopilosum.
I was going to guess baumgarteni, but the carapace is throwing me off too. The carapace on my baumgarteni female didn't start to darken up until she reached about 2". Before that, it was still very light.
I suppose it can darken up earlier than that, though.
