Mesonotal lobes completely absent; propodeal lobes in the form of weak convexities; in dorsal view spiracular gibbosities project from sides of propodeum, extending farther than propodeal lobes; spiracle openings face posteriorly; promesonotum uniformly foveate throughout; propodeal suture with longitudinal striae; dorsal face of propodeum longitudinally striate with a few foveae; propodeal suture in the form of an arched constriction, deeper laterally than medially, in profile not impressed, posterior mesonotum and dorsal face of propodeum meeting at very shallow angle; propodeal spines long, directed posteriorly; posterior face of propodeum nearly perpendicular to dorsal face, completely smooth and shining; dorsal face of pronotum broadly rounds into lateral face; lateral face foveate on upper half, grading into longitudinally striate on ventral half; anepisternum striatefoveate; katepisternum longitudinally striate; ventrolateral face of propodeum longitudinally striate; forecoxae striate; hind femur strongly swollen medially, spindle-shaped; outer surfaces of tibiae smooth and shining, with sparse piligerous puncta; posterior face of forefemur smooth and shining.

Petiole subcylindrical, longer than high, anterior face small, smooth and shining, posterodorsal face shallowly convex, rugose-foveate; ventral margin of petiole flat, with a ventrally directed, acute anterior tooth; postpetiole with gently sloping anterior face, a broad, rounded summit, and a more steeply sloping posterior face; anterior face rugose-foveate; posterior face foveate; ventral margin short, with a prominent, acute anterior tooth; first gastral tergite completely smooth and shining; first gastral sternites with anterolateral patches of oblique rugulae, remainder shiny with sparse piligerous puncta; second gastral tergite sublucid with microreticulate sculpture.

Face with fewer than 10 short, stiff setae; pronotum with about 10 short stiff setae along anterior border; mesonotum with six or fewer short stiff setae; dorsal face of propodeum with pair of short, stiff setae on lateral lobes, or these setae absent; petiolar dorsum with two and postpetiolar dorsum with about four longer, stiff setae; first gastral tergite with sparse, extremely short, completely appressed setae, no erect setae of any kind; first gastral sternites with dense, suberect, long pubescence; color entirely shining black.
