Arcuphantes arcuatulus? - Arcuphantes arcuatulus -

Cowichan Valley, British Columbia, Canada
November 9, 2012
Size: ~4mm body length

Found on the side of the house. His palps look like a good match for Arcuphantes arcuatulus from Chamberlin & Ivie 1943, as does his chelicera visible in the face shot (albeit the diagram in the paper is a posterior view).

Moved from Spiders.

That's clearly the male. (Unless Rod has come across a new Arcuphantes species that C & I didn't know about. But even that I doubt -- the match to the palp is too close.)

Nice work.

Great, thanks! I think we're on solid ground with this one, though Rod did mention regarding the female that there's a similar species in Oregon. That species might be undescribed, I didn't ask him what it was.

Arcuphantes arcuatulus?

I'll be looking forward to the answer. He certainly has impressive chelicerae.
