Solenopsis have shorter appendages, are much shinier, and diagnostically, have 10-jointed antennae with the last 2 segments forming a club (12 and 4 in Aphaenogaster).

 
Thanks a bundle, James,
for the explanation & move !!

Solenopsis sp

 
Good call, Margarethe !
It does look a lot like Solenopsis.
I had noticed the close resemblance, but couldn't find a good match as I somehow overlooked a few species in that genus, and subsequently started leaning toward Aphaenogaster; especially as I couldn't see its thorax spine/spike.

I agree that it resembles Solenopsis better than Aphaenogaster, but which characteristics eliminate Aphaenogaster ?

If is is indeed Solenopsis then it must very likely be Solenopsis xyloni.
