Looks
more like a Marpissa.
Old specimens may appear dark as a result of scales that rubbed off, but they do not darken with age. This specimen seems to have lost most of the scales on the OQ.

Thanks Jeff,
I confused spines with setae. "Tibia I with two pairs of ventral bulbous setae" was listed here (1) as the defining feature of Thiodina. I have attached the ventral image of this specimen which shows four spines with large bases which led to the confusion. Although there is very little detail, the appearance of the epigynum in this image is consistent with various drawings of Marpissa. Also the dorsal pattern on the abdomen is a good match for various drawings of M. formosa and similiar to this photo.
I have moved images to Salticidae. If you think there is sufficient information to further narrow the ID, please advise and I will move them.

It
does seem to match formosa, but maybe the genus page is good for now.
