That's normal for all New World T's. They rub of the urticating hairs with their back legs when they are irritated and want to be left alone. I have an A. seemanni that looks just like that. All of the hairs will return after the next molt. Have you notice that bahavior?
Shes been rubbing off urticating hairs, all new-worlders will do that sometimes. Just dont let the hairs get into your eyes, and wash your hands after handling her (if you do) if your hand starts to itch.
