Specimens have been collected from rainforest with many found as a single worker collected by Berlese funnel from leafmould or litter. Sympatric variously with Heteroponera trachypyx, Heteroponera viviennae and Heteroponera wilsoni.

Identification

Closely similar to the allopatric Heteroponera relicta but with the head, mesosoma and node medium-brown and the gaster more brightly orange brown, matching the antennae and legs. Sculpturing of scrobes, propodeal declivity and node posteriorly, and of borders of propodeal declivity as described for H. relicta.
