Oligolophus tridens is one of the short-legged harvestmen. They usually spend their life on the ground and do not climb plants, trees or walls. Of all short-legged harvestmen this is probably the most common. Alas, we couldn't find much information on the internet or in our books about this species.
Even though it is extremely likely indeed the animal in the pictures actually is Oligolophus tridens, we can not guarantee this.
