Hi,
I took these pictures many years ago (august 1984) in Arizona, at Tonto National Monument, east from Phoenix.
Of course they were analogic pictures, now digitalized from prints, and therefore are very bad pictures.
The specimen is an Heteroptera Coreidae.

I think its genus is Acanthocephala.
Do you confirm?

It's possible to identify its species?
Thanks a lot

Leptoglossus fulvicornis, perhaps?

Thanks Tony, it may be.

But why not Acantocephala femorata?

Could be - the hind tibial shape is a better match. I'm not familiar with these species, so don't know the range of colour variation, but the pale terminal antennnomere and the pale mid and fore tibiae of your specimen seemed to match fulvicornis.

According to BugGuide, A. femorata is a species of the Southeast. The common species of Acanthocephala in Arizona is A. thomasi. https://bugguide....view/16124

Thanks, John, for putting me straight!

Thanks, Jonn!
So do you confirm the genus is Acanthocephala, not Leptoglossus...?
Hi,

For Arizona I find A. declivis, here:
