Two Odontomachus in Mobile area
The uniform dark brown color doesn't fit O. ruginodis, which is in any case not recorded from the area. So, this is more likely O. brunneus or O. haematodus, but which of these species cannot be discerned from this photo - So, back to genus level.

Added later -- Correction, O. ruginodis has expanded to the Mobile area, as shown in the map here http://www.antweb.org/description.do?genus=odontomachus&name=ruginodis&rank=species. I still think this is not it - Note the color of the specimens imaged at the link.

Perhaps, but...
I would rather lean for the - very similar - introduced, and now more common than native O. brunneus, Odontomachus ruginodis. 1rst dorsal segment of the gaster appears to be shining, hairless or almost so, while O. brunneus' is hairy and has a distinct wooly to silky effect.
