I don't know to what particular specie belongs this ant, but looking at this older post of a wasp's jaw it's easy to understand that both ants and wasps belong to the same Superfamily: the Vespoidea from the order Hymenoptera.

This picture from Montserrat's monastery comes from the combination of the two pictures you can find below. To get it I used a photoshop gradient mask to softly transition from one image to the other. This allows me to preserve the best exposed areas from both images.
