I was going to say the same thing but didn't want to post first for fear of being labeled a noob (which would be rightfully so)first guess is P.lugardi.
How much did you pay for it?
I'm seconding this for now... until we get better pics. I really doubt it's a Pterinochilus.It looks like Chilobrachys to me .
I agree. I have one and they are pretty nasty. Watch those fingers!!! lolLooks like Chilobrachys Huahini. Give it some nice soft peat or cocofiber to dig around in. Keep the tank humid and keep your fingers out. I read they can obtain a 9" legspan. Never had one myself but would like to one day. Enjoy her/him.
