Neospintharus Species? https://bugguide.net/node/view/80631
Interesting – it seemed large for Neospintharus.
I could be way off. Itsy Bitsy will help you ID it. I have been out of the loop for a while.
(Sorry, hit the wrong little picture of a thumb.) It is definitely the same shape as Neospintharus, but a lot bigger than the one I got a poor, but at least identifiable shot of awhile back. I’ll post it.
It is similar, I’m not certain. :/
I found some old images of N. trigonum on my PC and have some that look like this. It was a really tiny one though.
Bradley’s book says N. trigonum females are in the range of 4mm TBL, males in the range of 3mm, so I suppose the spider in my photo could be in that range. But the individual in my verified Neospintharus photo was really tiny, <2mm. I guess Theridiidae is as close as we can get?
N. trigonum can look like this. I just don’t want to misfile it if you have reason to think it’s something else.
I re-read Bradley and ran this photo past Prof. Catley for third opinion – he agrees with you guys that it’s Neospintharus, and Bradley’s details certainly accord with what’s visible in the photo. So I’m satisfied, and I appreciate the guidance!
