Brown widows are an introduced species in North America. They live worldwide in tropical regions, so it is quite possible that since they are now in the USA, they will spread to all the areas in the US that are warm enough to sustain them. Arizona, New mexico, Louisiana, California.. and all the other southern states with a warm climate will probably be seeing these eventually. But what you have is most certainly a widow spider, and it's either a brown widow, or a morph of black widow or juvenile coloration that I have never seen before. Widows do go through a variety of marking changes as they mature, gradually gaining more black overall, until they retain only the red hourglass, and perhaps a few dots on the back. However, the shape of the hourglass on your specimen is not typical of any of the native North American widow spiders, but is identical to the hourglass on the definite brown widow in this picture:

So I would say that you do have a brown widow.
