Mecaphesa celer
Mecaphesa celer, if the following is a strictly ventral epigynum shot for this spider:



I have not yet posted the epigynum shots I have that best match this one, but I confirmed the ID (or rather, made the ID), from a dissected dorsal epigynum.

Further confirming this, I find that when a female M. celer has any dark coloration on her abdomen, there will at least be two pairs of spots at the anterior dorsum, with the anterior-most spots wider than those just posterior. Yours has that too.

It's also the best match for the location.
