this angle shows the posterior elytral spot reaching the epipleuron, and the hind tibia appears straight, not curved as in sayi.

See comments by Guy Hanley here and here. In photos of sayi in the Guide and at Cedar Creek, the posterior elytral spot doesn't reach the epipleuron, as it does in my specimen.

you're right...interesting...this specimen resembles either N. hybridus or N. obscurus, both of which I have specimens of in my collection and are pictured in the guide (from Calgary, AB). But where you found it is puzzling as neither species occurs in NB- both species have been described in a couple of reference sources as occuring in the Great Plains region which includes parts of AB.

Cannot be N. sayi because looks to me like the tibia are straight, only two species that fit what I see as straight tibia, all orange epipleuron, orange antennae, either N. hybridus or N. investigator Way to tell them apart is hybridus has stout setae on the humeral area extending to base of epipleural ridge, investigator setae end well before base of epipleural ridge. I cannot see the setae enough to tell for sure, but my guess based on elytral pattern, overall shape of pronotum, and location would be N. investigator not a big deal as far as distribution, I have half a dozen new state records from this summer alone....Most likely there have been specimens collected, just mis-identified.
