Reddish/Brown Beetle found near Salmon Arm British Columbia - Scaphinotus angusticollis

Reddish/Brown Beetle found near Salmon Arm British Columbia - Scaphinotus angusticollis
Salmon Arm, Saskatchewan, Canada
August 12, 2009
Size: 1.5 - 2 inches
We found this beetle near a waterfall in the mountains in British Columbia near Salmon Arm and Merrit. The reddish brown part of the body was very shiny and has a very dark stripe going down the middle. It didn't fly or move. It was about three inches long from the tip of its antennae to the end of its body. Never seen anything like it before. Hoping someone else can help us figure it out.

The narrow head
and pronotum set the Scaphinotus apart from other Ground Beetles. These features allow him to reach deeply into the shell of snails, his prefered prey.

The species?
I moved this to angusticollis because we clearly already had some look-alikes in that guide page. However, there are also several that look quite different and even have notes on them that they don't quite fit. We should probably move a whole bunch of them to genus level until a specialist can figure it out.
By the way, was this one really shiny or maybe just wet? (We have another one from Alaska with a similar note.)

For the record,
Scaphinotus angusticollis is reported by Lindroth (1961) to have elytra colored blackish to rusty red. Also interestingly, the catalogue by Bousquet & Larochelle (1993) lists no known species of Scaphinotus species in Saskatchewan. I will have to think more about being able to identify this species based on just the one photo presented here.

Geography error by submitter.
Top line says "British Columbia" correctly; second line says incorrectly "Saskatchewan". I discovered this discrepancy first today. So why did readers (especially the submitter) not question my original reference to "Saskatchewan"? Disappointed.
