This large, darkly coloured species is immediately recognisable by its densely sculptured propodeal dorsum, which is easily the most strongly sculptured in the boerorum group. In the region as a whole the propodeal sculpture of sulcatinasis is approached only by Hypoponera hebes, but that species belongs to the abeillei group.

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.

Bolton and Fisher (2011) - Measurements: HL 0.78–0.82, HW 0.65–0.70, HS 0.715–0.760, SL 0.60–0.65, PrW 0.48–0.54, WL 1.08–1.20, HFL 0.61–0.66, PeNL 0.22–0.24, PeH 0.50–0.56, PeNW 0.36–0.41, PeS 0.360–0.400 (15 measured). Indices: CI 82–85, SI 88–96, PeNI 72–79, LPeI 42–44, DPeI 164–178.
Eyes present, small but distinct, of about 4–6 ommatidia. In full-face view apex of scape, when laid straight back from its insertion, touches or slightly exceeds the midpoint of the posterior margin; SL/HL 0.75–0.80. Reticulate-punctulate sculpture of cephalic dorsum strong and conspicuous. Pronotal dorsum punctate, less densely so than head, the individual punctures distinct and more widely spaced. Lower half of side of pronotum much less densely sculptured than dorsum. Propodeal dorsum reticulate-punctate, the sculpture covering the entire surface; the sculptured dorsum contrasts strongly with the smooth, shining declivity. Mesonotal-mesopleural suture absent to vestigially present, and sometimes with a weak remnant of a transverse suture on the mesopleuron. Metanotal groove distinctly incised on dorsum of mesosoma; mesonotum with a well-defined posterior margin. Propodeal declivity separated from side by an angle or a weak margination, without sharp carinae. Mesopleuron mostly unsculptured but there may be weak sculpture peripherally. Petiole in profile with the anterior and posterior faces of the node usually very weakly convex and weakly convergent dorsally; node distinctly longer just above the anterior tubercle than at the dorsum. Subpetiolar process a lobe with a sharp or blunt ventral angle. Anterior margin of subpetiolar process, near its base, with a conspicuous pit from which a sensory seta arises. Maximum width of first gastral tergite in dorsal view subequal to or slightly greater than the width of the second tergite at its midlength. Base of cinctus of second gastral tergite with strong cross-ribs. Posttergite of second gastral segment, from posterior margin of cinctus to apex, distinctly broader than long. Disc of second gastral tergite reticulate-punctate to microreticulate, the sculpture strong and conspicuous. With first gastral segment in profile its dorsum usually without standing setae except at the apex of the tergite; occasionally one or two very short, inconspicuous setae may be present. Full adult colour dark brown, blackish brown, or mostly black; sometimes with reddish areas.
