Corinnidae - Trachelas
Nice job with the eye arrangement. I haven't created one for this family for my article here. Would it be okay with you if I use yours for now? I think your posterior lateral eyes may be a little low?

C. T. Tranquillus?
...according to this:

it's the only sub sp. I saw in our range...but then, I'm not very good at this, LOL
Not even sure the Guide drills stuff down that specific, but I felt like reading

Coming from you, that's a high compliment!
I'd be honored if you wanted to use my graphic for your chart! I use that all the time to ID the spiders I come across (ever since I completely mis-identified my lynx when I first started posting here)

I think you're right, though, not only are the p. lateral eyes low, I think the whole top row is too close to the bottom row.

The arrangement was traced directly from this shot:
and I think it's the camera angle that distorted the arrangement too much. If you wish to use it, I'd be happy to fix it first.

If it's not that much trouble please fix it. I tried to get into that PDF, but my computer or the site isn't cooperating this morning. I'll have to put it on my list to do.

No problem
I'll fix it and email it to you for approval

No need to email
You can just edit your eye arrangement post and upload the new one. Just let me know when it's ready.

I moved the top row up a bit and then adjusted the posterial laterals up as well.
