Hi Robert, I missed a very obvious detail the first time round. It is not M. gladstoni, proportions are wrong, so that can be eliminated. It turns out it is not M. lakinus either, because the prozona of the pronotum is the same length as the metazona. I should have noticed this right off, but didn't. In M. lakinus the prozona is distinctly longer. This makes it most likely M. femurrubrum, M. sanguinipes, or M. arizonae. It doesn't look at all like the first to me, and I suspect M. sanguinipes is much more likely in this area than M. arizonae. I still might be wrong, but that's my best guess, and I think almost certainly correct. Sorry about earlier confusion.

Learning as I go.

It's one of those females that are such a pain to identify, but it looks like a female long-winged M. lakinus to me. M. occidentalis looks a bit similar, but I think that's less likely both by association with the "normal" short-winged ones in your area, and the minor details of pattern that are more like M. lakinus.
