Spider Ant

With unusually long legs and antennae, this narrow-bodied ant looked more like a spider. It moved swiflty actoss the ground with its body held high and occasionally with its abdomen held vertically. The thorax, abdomen and legs were black with a bluish shimmer. The rest of the ant was a reddish brown.
