Thanks Dr. Thayer,
Using Downie and Arnett, from the genus this on keys very directly to P. alumnus Erichson, characterized as "common at lights" and seems to also match the general description well too (6 punctures on the pronotum, dilated tarsi, last 2 sterna notched apically). But given the size of the genus, perhaps there are other species close by?
Thanks again,
