Its relationship with other members of the mordax group is not clear. Mandibular dorsum smooth and shining with some punctulae; metacoxal spine present; subpetiolar process anteriorly projected ; gastric tergum 2 with basal one-half longitudinally costulate, the rest smooth and shining; disk of pospetiolar sternum smooth and shining; body black; legs and antennae brown.
