Difficult spider Male - Cybaeus reticulatus

From Rod Crawford:

Defintely a Cybaeus and the palp closeup is definitely reticulatus. It's odd, but I would have said from the whole spider photo that the palps were too narrow to be reticulatus, but looked more like eutypus or morosus. All 3 can occur in the same place. But if the closeups are definitely the same specimen, then my first impression stands corrected.

PS to Mandy, most American taxonomists use the left palp and most Europeans use the right. It's easy enough to reverse an image in this wondrous digital age of ours.

If the photographer lives in Grays River presumably he knows Bob Pyle...

Thanks, Rod

After my last mistake with the Tenuiphantes, it was a sigh of relief to hear I got this one right. I thought the same thing, too... the palps in the habitus image look skinny, but I just went with the palp image.

I mentioned the palp reversal because all the descriptions of this species are going to be the left palp. Just thought it would save people a step or two to have them already reversed (as far as I know, the only way to do this is first to copy an image to ones computer, then reverse it... which is avoidable if the photographer is given a heads up). Wasn't trying to split hairs, just thought I was making it quicker/easier for us other volunteers.

Moved from ID Request. I'm not sure if you already had, but I emailed Rod.

Likely Cybaeidae

I can see an apophysis on the palpal patella, which amaurobiids don't have, as far as I know.

Checked some diagrams...

Looks like he is Cybaeus reticulatus, one of the most common species in that genus. Hope Rod can confirm. I reversed the palp shot to help: http://i.imgur.com/elWdb.jpg

Looks like Amaurobiidae
