Thermonectus basillaris - Male
Medford, (~25 miles east of Philadelphia, PA) Burlington County, New Jersey, USA
June 28, 2008
Size: ~9mm
I believe this is Thermonectus basillaris - a first for me. corrections welcome :)

you can see several characteristics of the genus - Metatibal spurs each with apex finely emarginate (Aciliini), further, elytron densely punctate but punctures fine and inconspiciuous, AND mesofemur with hind margin setae longer than width of femur (1).

came to UV light
