Thanks Chad
Hope I didn't seem like I was trying to rush you, I just wasn't sure if you realized there wasn't a page for it or if you weren't positive with the ID.

This might be
Ceraticelus atriceps or the similar C. fissiceps. I don't have my Paquin & Duperre 2003 handy.

Looks like C. atriceps
The diagrams are very similar but this is different than the C. fissiceps female I posted recently and it lacks the schlerotized plate on the dorsal side of the abdomen that is apparently characteristic of C. fissiceps females.

Yes
That was why I suggested C. atriceps first. I call this pair the "squinty vikings"--at least that's what the epigyna look like to me.

Are we sure enough to make a page for this?
This is a new species for the guide.

On hold
John, I want to take some time and double-check your spider with my resources before doing so. Once I do that, if confirmed, I'll create and move the images.

Thanks
I also have what I think is a Tmarus minutus, I asked Laura to take a look but would like your input also.

LOL, I see ...
two squirrels!

Yep
I can definitely see those, Rorschach test in an epigynum...:)
