Big-headed ants in Lowveld

Observation - Big-headed ants in Lowveld - Southern Africa. Description: Between 1.9 and 2.mm. The major worker about 3.2mm. Spotted 3 individuals foraging on a cement floor, having emerged from a crack. I placed a drop of water with a just a touch of honey dissolved in it to make these small ants stay still for the camera.

Pretty soon the offering was covered in these ants. A single larger ant arrived. I think it is a major worker of the same colony.
Double-node petiole (side view).
Propodeal spines present.
