Western Sculptured Pine Borer - Chalcophora angulicollis

Western Sculptured Pine Borer - Chalcophora angulicollis
Thompson Falls, Sanders County, Montana, USA
July 27, 2005
Size: around 30 mm
From my info in the Peterson Field Guide, I would guess this is Chalcophora angulicollis - the largest buprestid in the Western US.

Lumped into C. virginiensis?
One reference I noted in the guide page for C. virginiensis said that C. angulicollis was now lumped into C. virginiensis. I'm certainly no expert.

I don't have a clue
Perhaps Phillip will know for sure.

 
I believe it's a valid name
I can't put my finger on the work that lumped these, but I'm still of the opinion thats its a valid name. See also here under distribution. I see Eric is of another opinion.
I see you've been busy - some nice western material.

 
Correction on lumping/moved to guide
Well, I had noted in the guide page for C. virginiensis that C. angulicollis had been lumped into the former species, quoting Milne. (1) However, consulting that reference, I see no such statement, so I must have misread it originally. I've corrected the guide page and added one for C. angulicollis, and moved this photo there.

Thanks for the quality control.

Note
Patrick,
Bright did indeed lump these in his monograph of Canadian Buprestids - but this wasn't based on a revision (isn't one!) - presumeably he based this on Wellso, et al paper on the Michigan fauna. Evidently, this isn't considered valid anymore - Bellamy and Nelson in American Beetles (1) says there are 5 spp. of Chalcophora for NA - see the references in my previous comment.

 
Just Patrick, not Eric
I just saw that statement about the species being lumped in Milne and Milne's Audubon Guide. (1) I believe they are entomologists, but they do not give references in that popular work. I was just passing that factoid along, certainly I don't have an opinion.
