What arthropod is in the picture?
It is not a pseudoscorpion as those would have 8 legs and then the two front large pincers. This is most likely a kind a jumping spider where the two large front legs count as two of the 8 legs.
Depending on your geography (not given in the question), this looks to resemble a jumping spider in the genus Chalcolecta (or some regional variant of that based on where you are). Hard to see any detail (like eyes and body segments) from your photos. But have a look at some of these and see if any of them match your specimen. Here are some pics of C.prensitans and C.simon.
