Collection records show this species inhabits a range of moist forest habitats and, with most collections having come from litter sampling, is apparently a soil or litter dwelling ant.
Identification
Weber (1942) - The thorax of this ant is like that of many Euponera species yet it has but one well-developed tibial spur on the middle and hind legs.

Description
Worker
Length extended about 2.5 mm. (of thorax 0.75 mm.). Head in front view, excluding mandibles, 1.1 times longer than broad and rectangular with rounded corners, occipital margin impressed, sides subparallel, feebly convex, anterior clypeal margin feebly convex; frontal lobes short, convex, carinae vestigial, frontal groove deep and distinct to middle of head from which it continues faintly to occiput; eyes vestigial, in front of middle of head; mandibles elongate, trigonal, with 8 denticles of irregular development of which two are distinct, and a long, acute apical tooth; antennal scape extends approximately to a level with the occipital corners; terminal funicular joint compressed and apically blunt, 0.08 x 0.24 mm., joints 8-10 squarish. Thorax with epinotum lowered and laterally compressed as in Euponera; from above the pro- and mesonotum appear ovate in outline, the pronotum being broader than long and with all sides strongly convex except for concave surface joining mesonotum; mesoepinotal impression distinct on sides. Petiolar node from above with convex anterior surface and plane posteriorly. 1st gastric segment from above broader than long, narrowed anteriorly, 2d segment larger. Legs of moderate proportions.
Shining, finely punctate. and sparse, upright, longer brownish yellow.
