Hypoponera inhabit and nest in leaf litter, the surface layer of soil, downed rotten wood, and soil around plant roots. Nests are typically found by turning objects on the ground, like downed wood and rocks, or through the ripping away of bark found on rotting downed wood or at the base of dead trees. Litter samples in tropical areas, especially in moist forested sites, often contain individuals of this genus. All Hypoponera are thought to be predators of small arthropods but published details about their diet are sparse. A lack of information about other aspects of their biology is also typical for most species.
The genus is most diverse in the tropics. Species found in higher latitudes tend to be more widespread, common and abundant than their tropical and subtropical congeners.
The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

Bolton and Fisher (2011) - It seems probable that sulcatinasis and transvaalensis may eventually prove to be nothing more than two geographical variants of a single species. But because the little material available can be separated by the characters given above, they are maintained as separate for the present.
Bolton and Fisher (2011) - Measurements: HL 0.88, HW 0.74, HS 0.810, SL 0.70, PrW 0.56, WL 1.26, HFL 0.70, PeNL 0.26, PeH 0.58, PeNW 0.40, PeS 0.413. Indices: CI 84, SI 95, PeNI 71, LPeI 45, DPeI 154.
A large, darkly coloured species, very closely related to Hypoponera sulcatinasis and answering the general description of that species, but differing as follows.
1 Dorsum of propodeum weakly sculptured anteriorly; the sculpture fades out posteriorly so that the posterior half is almost smooth. In sulcatinasis the entire propodeal dorsum is uniformly reticulate-punctate.
2 Propodeum without a sharply defined boundary between dorsum and declivity that is brought about by an abrupt loss of sculpture. In sulcatinasis the boundary between propodeal dorsum and declivity is strongly demarcated by the abrupt disappearance of sculpture at the junction of dorsum and declivity.
3 Punctate sculpture of pronotal and mesonotal dorsa weak and superficial; punctures very small and widely separated. In sulcatinasis the punctures on the pronotal and mesonotal dorsa are dense, sharply incised and conspicuous.
4 Metanotal groove with weakly defined anterior and posterior sutures, so that a narrow metanotal sclerite is present on the mesosomal dorsum. In sulcatinasis merely a groove is present.
