I thought the dark coloration on the top of the abdomen would make a species ID easy, but even after checking range maps and online images, I can't decide between several possibilities. There is a photo of similar looking specimens posted from El Paso, so the coloration seems rather distinctive and western in TX distribution. No big help there.
