Known only from the Cape Tribulation area. Most samples are of a single worker collected by Berlese funnel from rainforest leafmould or litter. Sympatric with the similarly bicolored Heteroponera rhodopygea at Roaring Meg Creek, and with Heteroponera rhodopygea and Heteroponera wilsoni in the Cape Tribulation area and at Mc Dowall Creek.

Antennal scrobes smooth and shining with slight minute surface rippling. Propodeal declivity smooth and shining, the area reduced in size compared to other species, its borders barely raised; posterior face of petiolar node smooth and shining, merging above with the similarly unsculptured dorsum. Head relatively large and broad; eyes more protrusive in frontal view than in other species. Mesosoma relatively short and dorsally inflated—its profile with an almost semicircular dorsal arc in lateral view. Humeral epaulets well developed. Petiole relatively short and broad in lateral view, approximately as long as high, rounded above in profile.
