The Philodromus aureolus group is one of the most difficult to identify to species level, and one where many misidentifications have occurred. P. praedatus and longipalpis seem to provide the greatest difficulty and records of these should involve voucher specimens checked by an experienced arachnologists familar with the species. Very careful microscopical examination of adult female epigyne/male palp is essential, and sometimes dissection is required for confirmation.
It is impossible to be sure from your photograph and the small size of the inset epigyne, but it appears to show the arch dividing the epigyne of cespitum. However it simply isn't possible to see enough without a specimen under a microscope.
