Black Trunk Ant

Size about 10-11mm, found on Dragon Fruit, moving fast but rarely using its wings. This animal might not be a winged ant. It is certainly a Hymenoptera. Its body form and big compound eyes point towards a wasp. Its mandibles have obviously been transformed into a sucking trunk. Happy to get any suggestions for this species proper identification. This gallery almost certainly will be removed and the animal renamed, when or rather if I can get a better idea of what exactly it is.
