The genus Philodromus is a member of the Thomisidae, which includes Xysticus cristatus , for example. Unlike Xyticus sp. the members of genus Philodromus pursue their prey more actively, as opposed to lying in wait. To help with mobility, Philodromus sp. has tufts (scopulae) on all four pairs of legs. The photo is of a male of the species.

Note the scopula hairs below the visible claw, and compare this with the much reduced scopula on Xysticus cristatus||Pedipalp of a female Philodromus cespitum. The single claw can just be made out among the scopula hairs to the left of the image, about 1/3rd of the way up.|
