I don't believe it's a Poecilometis. The proportions are wrong (e.g. large head, wide body), and the membrane (end part of the forewing, black in this sp. and in Poecilometis patruelis) has a different pattern of veins, and they bare white. I had a look online for this one, couldn't find anything matching it. Will keep trying.
I see what you mean Kim.... Hint re comments - if you click on the icon that looks like a square with an "i" at an angle, then you can edit your comments.
Michael M, before I Undo your confirmation, and then Undo my (incorrect) suggestion of Poecilometis patruelis, I'm drawing your attention to Kim P's comments, ie not Poecilometis. Here is a good example of where being able to Undo suggestions is really useful.
A good outcome. I did look at Oncocoris but the specimens ilustrated looked much browner. In fact the common name of one of the species is brown stink bug
