Solenopsis amblychila, has a lovely golden color, especially in strong sunlight. They are very similar to Solenopsis aurea (the Golden Fire Ant) - in fact, I had originally misidentified these ants as Solenopsis aurea. It is quite difficult to tell the two species apart.
I mainly have found these fellows on cactus extrafloral nectaries.
Solenopsis aurea is often found on cactus extrafloral nectaries, as in these Apple QuickTime videos:
