Color dark red brown to black.

Mandible largely smooth and shiny, with very faint striae; clypeus emarginate anteriorly, convex, smooth and shiny; face smooth and shiny; scape with moderately abundant, short, fully appressed pilosity and no erect setae; terminal 2-3 segments of antenna sequentially longer and more densely pubescent, especially terminal two, forming 2-segmented club; face and ventral surface of head with sparse short appressed pubescence and no erect setae; no erect setae projecting from sides of head in full face view.

In lateral view, promesonotum compressed, pronotum short but strongly convex, mesonotum projecting above pronotum and propodeum, dropping steeply to propodeal suture; propodeum with short, weakly differentiated dorsal face; propodeal suture deep, Vshaped, but suture partially obscured in lateral view by small lateral carinulae that bridge suture; propodeal spines short, conical, upturned; side and most of dorsum of mesosoma with faint punctation or weak microareolate sculpture, becoming smooth and shiny on posterior face of propodeum; mesonotum with a pair of short, stiff, erect setae, otherwise erect setae lacking on mesosoma; legs with sparse, fully appressed pubescence.

Petiole in side view subtrapezoideal, with faint microareolate surface sculpture; anteroventral tooth a shallow, obtuse gibbosity, not produced or angulate; dorsal face subrectangular, slightly longer than wide, smooth and shiny, anterolateral portions somewhat produced as lobes, anteromedian region depressed, sides approximately parallel anteriorly, converging posteriorly; postpetiole with small acute ventral tooth, postpetiole in dorsal view bilobed, wider than long, with longitudinal median sulcus, posterior margin emarginate; fourth abdominal tergite with faint microareolate sculpture; pair of stiff setae on posterodorsal petiole, two pairs on postpetiole, and about 20 stiff setae on fourth abdominal tergite.

Queen
Longino (2003) - In lateral profile dorsal face of propodeum sloping obliquely from postscutellum, such that most of propodeum is posterior to scutellum (in contrast to normal queens, in which dorsal face of propodeum drops steeply from postscutellum and much of propodeum appears ventral to scutellum and postscutellum); entire body, including scape, mandible, face, mesosoma, petiole, postpetiole, and fourth abdominal tergite extremely smooth and shiny, glass-like; propodeal spines completely absent; petiole and postpetiole robust, generally similar to worker in shape but completely lacking anteroventral petiolar tooth of any kind; remarkably devoid of erect setae or pubescence, funiculus and terminal segments of tarsi with typical subdecumbent pubescence, but no trace of pubescence or erect setae anywhere else on body; size characters as in Figures.
