Here's a paper on the burrow of this specie:

BTW... I've realized that i was confounding the palpi with legs. They're very long and really look like another pair of legs

Rebecca you're right we have the Hebestatis lanthanus here, but i can't find even a single picture to compare with mine... So this remains unknown to me, probably i' should go to Universidad de Costa Rica to ask, i read they have one specimen there... Maybe they can help me
Thanks a lot for your help, at least i think i've got the right direction

Habitat looks like a trap door and there is one exclusive to Costa Rica (hebestatis) but it has a more red hue. Great shot!

Wonderful photo

You could always bait her with a bug, and see if that works. Ive managed to take some good photos of spiders that way. Not very practical, but it works.

Tamir you're right it really seems like a claw! I haven't seen it that way, Cool!
I think is a funnel weaver, but it's really hard to get an ID because she never gets out from her refuge, so i can only see this part of her body, for me is not enough for a confiable ID.
@shebebusynow i think she's creepy because looks like the spiders you see in the most of the horror movies... But i agree, the lack of hair in the legs makes her look more dangerous she probably is

I think what makes it particularly creepy is the lack of hairs on the legs. Seems like most big spiders are also pretty hairy. It really does look more like a claw.

That looks like a funnel weaver. Funnel weavers exist practically everywhere, so you shouldnt rule that you are correct.
