Hi Rinney. I agree with Mauna. I found a couple sites for Harvestmen in PA. One site only gives the Leiobunum vittatum for PA. <https://www.insectidentification.org/insect-description.asp?identification=Eastern-Harvestman>
The same site also gives the Leiobunum spp. <https://www.insectidentification.org/insect-description.asp?identification=Harvestman>
In either case, I think Leiobunum spp. would be a safe classification.
