. Small species (HW 0.47–0.78, HL 0.65–0.93); head longer than broad (CI 0.69–0.85) and eyes strikingly elongate (REL 0.55–0.66). Masticatory margin of mandible with 5–6 teeth; mesial tooth on basal margin about equidistant between apicobasal angle and proximal tooth. Palp formula 5,3 or 4,3. Anterior margin of median clypeal lobe broadly concave, with a weak median protrusion, and with sharp lateral angles. Frontal carinae closely contiguous (FCI 0.010–0.019) and forming a thin anterodorsally elevated ridge, the carinae directed forward onto the median clypeal lobe rather than fusing with the antennal sclerites anterolaterally. Profemur very robust (FI 0.49–0.56). Metanotal groove strongly impressed (

). Dorsal and declivitous faces of propodeum well differentiated; in profile the juncture between the two varying from weakly to strongly angulate, sometimes producing small, paired tubercles. Petiole relatively short (PL/HL 0.35–0.49), longer than high or wide (PLI 0.51– 0.80, PWI 0.48–0.66), and without a well differentiated anterior peduncle; anteroventral petiolar tooth present. Postpetiole broader than long, with small anteroventral tooth. Body sculpture varying from smooth and shining, with scattered fine punctulae, to densely punctulate-coriarious or coriarious-imbricate. Standing pilosity very sparse (MSC 0–2), a single pair or none at all on dorsum of head, mesosoma (pronotum), petiole and postpetiole; absent from the extensor faces of tibiae (HTC 0, MTC 0). Appressed pubescence moderately dense on petiole, postpetiole and abdominal tergite IV, variably so on rest of body. Color varying from brownish-yellow to dark brown, often bicolored.

. Similar to worker except for caste-specific differences. Head more elongate (HL 0.74–0.97, CI 0.62–0.78); median clypeal lobe more protruding; profemur more robust (FI 0.53–0.59); dorsal face of propodeum shorter than declivitous face, the juncture between the two gently rounded, not angulate. Petiole generally more slender than in worker (PL/HL 0.46–0.51, PLI 0.57–0.67, PWI 0.50–0.58). Forewing with 2 submarginal cells, i.e., cross-vein 2rs-m present.

. Relatively small species (HW 0.53–0.69, HL 0.58–0.74; n = 4). Head longer than broad (CI 0.88–0.92); compound eye large, prominent (REL 0.55–0.60, REL2 0.62–0.65). Mandibles with about 6–8 teeth or denticles on masticatory margin. Palp formula as in females. Surface of median clypeal lobe convex, its anterior margin subtriangular in shape (dorsal view) with sides converging medially to a rounded point. Scape short (SI 0.20–0.23). Petiole and postpetiole slender (PLI 0.54–0.59, PWI 0.41–0.49). Posterolateral corners of sternites IV– VIII not notably protruding ventrally. Posterior margin of subgenital plate (sternite IX) broadly convex, lacking conspicuous posteromedial concavity. Posterior margin of pygidium (tergite VIII) convex, directed posteroventrally. Paramere with angulate or rounded posterodorsal extremity, and a low angulate mediodorsal lobe (as seen in lateral view) representing the summit of a well-developed mesial dorsoventral ridge. Aedeagus with somewhat expanded posterodorsal corner; posterior margin with numerous small teeth (10+), preceded by a sinuous carina on the outer face of the aedeaegus, which converges to the posterior margin dorsally.
