Agelenopsis or Barronopsis
Rod Crawford says

"I really don't know much about Coras. I've never seen a live one and
rarely even a preserved one. According to "Spiders of Connecticut"
they have geniculate chelicerae (elbowed, projecting forward before
projecting down, like in Cybaeus), which might help.

That doesn't apply to the present specimen, which is neither one. Its
procurved eyes (visible in the large version of the front view) show
it to be an Agelenopsis or Barronopsis (those are the only 2 genera in
the Agelenini tribe that occur in the SE - here in the west there'd be
several other possibilities)."

I looked through the ones mentioned above and couldnt find a visual

neither can I
We may just have to put this one aside for now, until we can get more info.

Mataltella sp.? Lynnette, I have not had hands on with this genus, and I cannot see the eyes on this photo. Maybe it is 'my' eyes ... as it seems others have commented on the eye pattern.

I looked at this and this to compare.

That certainly seems like it fits as well. I think this one is beyond me.

Johnnyn added this recent eye shot (thanx John). From photo evidence I can state that this spider is very likely Metaltella simoni, family Amphinectidae . This spider is common in Mississippi, though it is not indigenous to the US and there has been concern about displacement of native Amaurobioidae (M. simoni previously classified Amaurobioidae) Titanoeca brunnea .

Size of imported Amaurobioidae M. simoni = 7-9 mm.

Thanks for the effort in id.
I guess I can move to page now,also link above is broken.

Sorry about that,

Lets try a link to the pdf

more info

Let me know if you have any trouble with this one John, and BTW, thank you for this post.

link is good,interesting and thanks again,both You & Lynette

From Rod
I never considered that it might be amaurobioid because it appears to
have projecting, visible-from-above spinnerets, something never seen
in the amaurobiids I'm familiar with. The palp does look similar to
Metaltella. I didn't know Metaltella had procurved eye rows; I've
never seen one and the only description of it I have on hand doesn't
mention that feature, one that I've never seen on any amaurobioid
familiar to me.

Like I'm always telling people, an arachnologist in Seattle is not
necessarily the best person to send your spider photos from Florida,
Vermont, Quebec, Ireland, Australia, etc. to. All these places do have
*local* arachnologists. The spiders I should be looking at are those
from the Pacific NW plus Utah and Alaska.

Male spider
I'm not sure but it reminds me of this one placed in the Coras genus.

That looks close,it appears to be in Amaurobiidae family but im not an
expert and I didnt get a good eye shot.

Could be Amaurobiidae
I think your eye shot is pretty decent. These are both good shots. The only other thing I can think of that is similar is the genus Tegenaria, Family Agelenidae. The eye arrangement of Coras and Tegenaria are fairly similar and so are their general appearance. I also find both in very similar places, making them hard to tell apart.

is glare on the eyes though,I am using a new ringlight and still getting used to it,do you think I should have diffused some?

from what I've experienced it never hurts. I'm not that great with my ringtlight, though.

Also, I cropped and lightened this image for you.
