Most specimens have been collected from rainforest litter samples, with the few exceptions being those obtained from "stick brushings" and under a stone.

Worker: Similar to the generally more southerly distributed Heteroponera leae. Salient differences are: (1) propodeal and petiolar denticles larger and more sharply acute; (2) reflexure of second gastral segment more pronounced – in side view the profile is less evenly arched than in H. leae, with a tightly curved median section; (3) first gastral tergite more-or-less evenly sculptured with coarse semi-foveate punctate-rugosity, the raised elements forming a somewhat longitudinally biased reticulum; (4) second gastral tergite similarly, but more finely punctate-rugose, the longitudinal component clearly evident, but much less well-developed than in H. leae; the whole more reticulate than in H. leae.
Queen: Appropriate characters consistent with those of the workers. Propodeal and petiolar spines a little less prominent. Gastral reflexure and sculpturation as in worker.

The gyne was formerly alate, as evidenced by the presence of torn wing stubs. She thus resembles those described for the Neotropical species Heteroponera dentinodis and Heteroponera inermis. Some other species, like Heteroponera relicta and Heteroponera brounii, have wingless ergatoid queens with reduced mesosomal structure. Gamergate reproductives (mated workers) have not been reported for any Heteroponera species.
