Darkling Beetle - Platydema excavatum - male

Darkling Beetle - Platydema excavatum - Male
Earthquake Hollow Conservation Area, Callaway County, Missouri, USA
March 25, 2012
Size: very small - maybe 3-4mm
Found quite a few creatures under the tree bark yesterday, including this one. By far it was the smallest. To the naked eye, the grooved surface was not visable, just looked very shiny and dark. When disturbed they went faster in every direction & re-huddled. Any idea what type of beetle/bug this is?
