The type material was collected from a rainforest soil core. The other known sample, a worker, was found at an hypogaeic oil bait.

Borowiec (2009) - This species is most easily separated from its congeners by its peculiar falcate mandibles. These are elongate, somewhat resembling the condition observed in Dorylus, with the narrow masticatory margin equipped with two (excluding apical) well visible teeth and meeting the long basal margin at an obtuse angle, resulting in a wide gap between mandibles and clypeal margin at closure.

Head almost as wide as long, widest at about midlength; sides parallel, slightly convex and converging anteriorly and posteriorly at about one fifth of head length; vertexal margin shallowly concave. Parafrontal ridges completely absent. Mandibles narrow and long; when closed, basal margin separated from anterior clypeal margin by wide gap. Basal margin long, meeting masticatory at obtuse angle; masicatory margin with two blunt teeth basally; remainder of margin elongated into broadly rounded apical tooth. Lateroclypeal tooth a small tubercle. Lateral portion of clypeus poorly developed, consisting only of semi-circular ridge surrounding antennal insertion. Antennae 12-segmented. Palp formula unknown.
Mesosoma moderately stout, rectangular in dorsal view; dorsal surface flattened, bordered at the lateral sides by a distinct angle but with no margin. Openings of propodeal spiracles broadly oval, directed outwardly and upwardly at angle of 45°. Declivous face of propodeum immarginate above propodeal lobes. Propodeal lobes very small. Front femur short, very broad, and laterally compressed. Metatibial gland a whitish, elongate patch of cuticle, little longer than maximum width of hind tibia.
Petiole about as long as wide, with well developed dorsal and posterior faces. Subpetiolar process short and moderately broad; in side view with ventral margin sloping towards posterior end; translucent narrowing present along ventral margin, lamella gradually widening distally.
Abdominal tergite III wide relative to following segment, in side view the whole segment is robust, with developed anterior, perpendicular face.
Pygidial field small, weakly impressed with four teeth on each side.
Mandibles sculptured with widely spaced punctures, interspaces shining. Head with regular punctures, spaced from about half of their diameter on dorsal and anterior lateral surfaces, to wider than diameter in posterior lateral section. Similar sculpture on dorsal surface of mesosoma with longitudinal stripe devoid of sculpturation in middle. All interspaces shining. Lateral sides of mesosoma microreticulate, only area around propodeal spiracle devoid of any sculpture and shining. Sides of petiole microreticulate.
Body pilosity composed of (1) dense, subdecumbent hairs present on head, mesosoma, and abdominal segments and (2) about one and half times longer, subdecumbent to suberect hairs present on the pronotal shoulders, propodeum, petiole, margins of gastral tergites. Outer surface of middle tibiae with two modified peg-like setae.
Color: yellowish-orange with brownish mandibles and genal areas around mandibular insertions.
