Moved from Limonius.

Moved, Limonius sp.
Check to see if nimbatus or definitus gets in the PNW. My sources are not handy at the moment. Def something in that group.

Moved from Click Beetles.

Well this really is an intere
Well this really is an interesting beast.

Using the Al Dhafer (2009) key it does indeed fit the the nimbatus/ definitus group. The only real option on this coast is the very variable L. ornatulus. Now if I had not dissected the male genitalia I would have found the following image and been happy with that species.

However, the aedeagus pictured of L. oranatulus is very different in that both the parameres and the aedeagus have rounded tips. The image itself is not great but it is clear to see it does not look like the one I have here. All the other characters fit including some rather odd changes in puncture density and size.

There is an image of L.ornatulus at the Spencer Collection that can be seen here. In that picture you can see the parameres and aedeagus tips and they appear to match what I have pictured and not those illustrated in Al Dhafer.

If I follow the key in Van Dyke I get to L. maculicollis which was lumped in the L. ornatulus.

Could there be more than one species in L. ornatulus? Or perhaps there is more variation in the male genitalia then the one image in the paper can show.

could be...
Al Dhafer's work, well, leaves some things to be desired. The image above (that I moved) was a tentative ID based on general morphology. I am at work now, does Al Dhafer's work mention anything in synonymy with ornatulus? Perhaps something that should not be a synonym? I cannot access the link above, whatever site it's one is blocked at my work?!? I'll have to investigate at another time.

The link does not work for me either. Here is a link to all the Elateridae in the collection. If you scroll to L. ornatulus the dorsal image is the one I was referring to.

Al Dhafer synonymized L. maculicollis. I have not found any reference to the male genitalia of that species but I wonder if that is the beast I have and that it is different from L. ornatulus.

Thanks Blaine
Both of those are eastern species. I'll try and spend some time with the key and see if I can find what it might be from out this way.
