Lioponera clarki

Brown (1975) - In Australia, a raid of L. clarki was observed in 1951 in open eucalypt woodland at Berrimah, near Darwin, Northern Territory, over bare soil against a nest of a small Iridomyrmex in bright morning sunlight. This raid was very loose and involved only 3 or 4 Lioponera workers while I watched it, so it may have been the final stages of an action begun much earlier.

Identification
Heterick (2009) - Lioponera clarki is distinguished by the lack of a dorsolateral cephalic carina curving towards the eye, lack of ocelli and a wide node with posterior angles that in dorsal view extend laterally beyond its anterior margin.
