Moved from Dendrocoris.

Moving it for now. If someone else comes along and disagrees, feel free to discuss.

All right. I think I keyed this out.

I could have made a mistake though, so please feel more than free to check my work.

Using the genus key that's on the info page here:
http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1319&context=insectamundi&sei-redir=1#search=

1. Vertex of head tumid or flat.
2. Cicatrices contrastingly darkened/cicatrices concolorous with dorsum.
4. Anterolateral pronotal margin thick; head elongate/Anterolateral margins of pronotum thin, compressed; head length about equal to width
5. Head, pronotum, and pleura devoid of dark punctations/Head, pronotum, and pleura with numerous dark punctations

That last couplet points to D. pini. The description of the species in the reference seems to make sense.
Remarks on D. pini from the reference:
"The lack of dark punctations on the dorsum and pleura are diagnostic. As indicated by the name, the host plant is pine. Records of this insect from further east than the states mentioned probably refer to related species."

Interestingly, the placeholder in the guide for D. pini seems to have numerous dark punctations and is from an undisclosed part of the US. I wonder if this is one of those eastern collections that is actually a related species.
Placeholder

What do you think? D. parapini is only recorded from TX/NM too, while D. pini has previous California records.

Wow -

awesome work, thanks Andrew! In an ideal world, you would also have access to a museum with a reference collection of pentatomids, including members of this genus, so that you could have some "gold standard" specimens to compare to... looks good to me though, feel free to move as you see fit, I don't have any experience with keying pentatomids or even the terminology...

Maybe...

Dendrocoris parapini? Info says food plant is Pinyon Pine...

Wow

I bet you're right. What a find.

Thanks -

looks possible, though would apparently be a range extension (known from NM and TX?).
