slug eater - Sphaeroderus stenostomus

slug eater - Sphaeroderus stenostomus
Mt. Washington, Coos County, New Hampshire, USA
Size: about 13 mm
Found in the splintered end of a Balsam Fir log. This image is actually two merged to get more parts in focus. This beetle was one of the many collateral benefits in my Forest Service-approved search for Py*tho str*ictus.

Sphaeroderus subspecies - three in NH
I'm curious as to what key you used? I am aware of three subspecies of Sphaeroderus reported in NH --- 1: S. canadensis canadensis, 2: S. nitidicollis brevoorti, 3: S. stenostomus lecontei. The image appears to show more than 11 striae per elytron which would preclude (1) and a distinct non-pitted convexity lateral to each basal fovea of pronotum would preclude (2). Your image is not unlike (3) which I see commonly in WI. Images can be deceiving as you know. See images of all three under Tribe Cychrini

 
I'm posting more images that might help decide subspecies.
I agree that number three seems likeliest as well.

 
Sphaeroderus stenostomus lecontei
Nice clear extra images which settle Sphaeroderus stenostomus lecontei in my mind.

 
Thank you, Peter.
I'll move it there.
