Flat Bug - Aradus robustus

Flat Bug - Aradus robustus
Horner Park, Richmond Hill (N43º52'20.8"W079º24'41.8"elev.190m), York Region, Ontario, Canada
May 25, 2008
Size: 6 mm
Another Aradid for Ontario. This one was found basking on a bare, bark-less trunk, as you can tell from the background (it was extremely cooperative, too.) I wonder if it could possibly be the adult version of this ?
Quite sure it's in the genus Aradus, but do correct me if I'm wrong.

Moved from Aradus.

I agree
I agree, probably Aradus robustus (which is also fairly common)

Aradus robustus
Looks like Aradus robustus, if the scutellum is subpentagonal and not raised behind middle, I can't see it that well, but it matches my specimens perfectly.

The scutellum
in my specimen is not raised behind middle. Matches illustration in Marshall(1) as well.
