Tim Manolis found this small and regionally rare spider in his home and I photographed it a few days later. He tentatively identified it as P. rufus and got confirmation from Rick Vetter. The spider will be given to the California Academy of Sciences for further confirmation and preservation as a specimen. This is likely the northernmost record for this species in North America?

Need an ID on this spider I found in the forest in Pennsylvania on 5/19/2015 near Lake Pymatuning. - Pityohyphantes - Linesville, Crawford County, Pennsylvania, USA
May 19, 2015
Size: Abdomen = ~0.5cm diameter
Found this spider in the woods surrounding a large lake. It builds a 2D horizontal capture web, with some vertical support threads. It sort of resembles a house spider, but the web it makes differs, and the coloration on its back doesn't seem to match. This spider had a brown abdomen that slowly fades to white as you move to the top, yet the top has a sort of arrow-shaped or tire tread patterns. It also had a dark line running anterior-posterior in the center of its prosoma. My field season studying wasps appears to be a flop, and I see these spiders all over. I would like to devise a study with thm this summer, but need help identifying them first!
