I add some photos. I do not know if it will help or not. They can be frass anytime.

Seems close to Mermessus tridentatus (Eperigone tridentata)
Fits the description and palp diagram in Crosby and Bishop, 1928 pretty closely as far as what is visible in these photos. The description seems to describe the teeth on the lateral edge of the chelicerae as well as the large downcurved frontal tooth. The pattern is a reasonably good match for the drawings in Edwards, 1993 and the photo here - (1).

 
Thank you
I think you have right. It could be Mermessus tridentatus but I'm not enough skill to take the decision to move the photos.
In this case the very distinctive spines on the chelicerae led me to add so many photos. Unfortunately I was not able to catch better the details.

 
I'm waiting for a second opinion
from Laura or Chad, but I do think M. tridentatus is a good fit.

 
The WSC lists ...
34 species in the genus in NA ... I don't think I can be sure of species without a clear shot or at least trying to look over all of them and seeing what can be ruled out, the genus sure looks right though.

I'm sorry for photos. The spider was too small. I don't know if Catalogue of Texas Spider can help a little. Are 10 species of Mermessus in Texas.

 
Usually the most important shot
is a ventral view of the palp which is not easy to photograph on a live specimen and with small spiders it can be hard to get a good photo without a microscope or a very good lens.

male sheetweb spider
but beyond that I don't know. There are quite a few that seem to look like this. Perhaps someone else can tell you more based on your palp images... A good side view of the palp sides can help.

Compare with


If I had to guess I'd say Bathyphantes.

 
The general shape of the palp
reminds me of Erigone or maybe Mermessus. Looks to have some very distinctive spines on the chelicerae, they should help in a diagnosis.
