Clytus ________? - Xylotrechus insignis

Clytus ________? - Xylotrechus insignis
South of Redcrest about a tenth of a mile from the South Fork of the Eel River, Humboldt County, California, USA
June 28, 2009
Size: Maybe 15mm
My first impression as I saw it fly was that it was a wasp. I was amazed when it landed and I saw it was a beetle. It is very similar to Clytus planifrons but the yellow markings extend along the entire front edge of the wing covers.

nice, nice! it does look like a Clytus -- rather fancy one, too
don't see a satisfactory match yet [complete band across elytral base seems peculiar] -- will ask around, i scarcely know them

It looks closest to
Clytus planifrons (LeConte).

I had been pondering...
...whether it might be C. marginicollis, mostly because there was a similar looking image in the guide which was also posted from CA. Then, I checked the Info page and it states that C. marginicollis is an east coast species. Could you take a look at this image and make sure that it has been identified correctly and is not actually C. planifrons?

thanks--
we've got just 2 images of planifrons, none with a hint of this solid basal band across the scutellum

I agree
that this is Xylotrechus insignis. They're damn close though.
