Size: ~2 mm
Try as I might, I couldn't get a good photo. Found in some leaf litter as Jeff suggested here:

Not exactly one of the the high quality photos he was looking for, but it's interesting nonetheless.

Didion punctatum (Melsheimer)
Det. E. G. Riley, 2012

glad someone looked at it!
I still think it looks like it has too many tarsal segments but the photo quality doesn't allow an accurate count.

Wide-ranging Melsheimer bug
Kinda surprising no one else has shot it...

Wonder if it is related to Tritoma??

Moved from Dusky Lady Beetles.

scymnine or not?
The antennae seem too long and robust - Scymninae species usually have narrow, thread-like antenna. In this photo, the shape appears squared-off towards the rear, not rounded and oval.

It's hard to tell from the photo, but this actually doesn't read as a coccinellid to me. I keep getting more than 3 when I try to count the tarsal segments in the hind leg, too - I adjusted contrast and sharpness in Photoshop to heighten the outlines, and there seem to be at least 4. Coccinellids have a 3-3-3 tarsal formula.

Moved from Ladybird Beetles.

Moved from Beetles.

Scymnini tribe.

for the correction, Boris.

other photos?
any other images of this beetle? There don't seem to be too many with all black pronotum and this elytra coloration. Any head / tail shots might be helpful too.
