Mandible longitudinally costulate. Scapes relatively long (SI 115-132); when laid straight back in full-face view the apex of the scape very obviously exceeds the posterior margin of the head. With head in full-face view the eyes at the midlength of the side of the head capsule. EL 0.20-0.24 (EL/HW 0.29-0.32). Dorsum of head from level of eyes to posterior margin almost smooth, with only faint, superficial remnants of reticulate or feeble, disorganised punctulate sculpture. Promesonotum in profile convex and swollen, the mesonotum with a long posterior slope that descends to the very feebly indicated metanotal groove. In absolute profile the propodeal dorsum is horizontal, flat to very nearly flat, posteriorly with a bluntly rounded angle. The whole propodeal dorsum is strongly depressed with respect to the highest point of the promesonotum, which is on a considerably higher level. Pronotum with 3-5 pairs of setae; mesonotum with 2-3 pairs; dorsum of propodeum lacks standing setae. Pronotal dorsum usually with weak, superficial reticulate-punctulate sculpture, at least near the midline; sometimes the sculpture reduced to microreticulation, but the surface never entirely smooth and polished. Propodeal dorsum very finely and densely reticulate-punctulate, the sculpture usually more distinct than on the pronotal dorsum. Side of pronotum superficially microreticulate to weakly reticulate-punctulate; mesopleuron and metapleuron finely and densely reticulate-punctate. Metafemur appears strongly incrassate, with MfL 0.88-1.10 (MfL/HW 1.28-1.39, MfL/MfH 3.62-4.15). Petiole with one pair of setae, on its posterior face near the base; postpetiole with setae on its dorsal and posterior faces; first gastral tergite with numerous suberect setae that are shorter than the maximum vertical diameter of the eye. Postpetiole relatively narrow in dorsal view, maximum width 0.20-0.24 (ca 0.30 x HW). Dorsum of postpetiole with very weak reticulate-punctulate or superficial granulate sculpture, sometimes vestigial. First gastral tergite unsculptured, or at most with traces of superficial microreticulate patterning. Entirety of head, mesosoma, petiole, postpetiole, legs and gaster yellow.</paragraph>

TL 6.4-7.1, HL 1.24-1.26, HW 1.16-1.22, CI 94-97, SL 1.02-1.04, SI 84-89, PW 0.88-1.02, WL 2.06-2.14, EL 0.36-0.38 (EL/HW 0.30-0.32), MfL 1.20-1.26 (MfL/HW 1.00-1.07, MfL/MfH 4.20-4.40), maximum dorsal length of mesoscutum 1.00-1.05, maximum width of mesoscutum 0.95-1.07, maximum dorsal width of postpetiole 0.42-0.48 (0.38-0.39 x HW) (5 measured). Head somewhat more strongly sculptured than in worker, and with weak longitudinal costulae in front of the ocelli. Mesoscutum unsculptured except for minute, widely scattered pits; mesoscutellum unsculptured, smooth. Propodeal dorsum with fine transverse costulae, between which are traces of superficial punctulation. Petiole, and postpetiole finely reticulate-punctate. First gastral tergite unsculptured, or with superficial vestiges of faint microreticular patterning. Side of mesosoma mostly smooth, with scattered patches of minute weak punctulae or microreticulation. Propodeum rounded to very bluntly and obtusely angular posteriorly, without a well-defined tooth or dentiform angle between dorsum and declivity. All dorsal surfaces except propodeum with numerous fine setae; propodeum entirely lacks setae. Colour generally as in worker, but apex of each gastral tergite with a darker transverse band.

, together characterised by a 4-segmented antennal club in which funicular segments 8 and 9 are of equal length, uniform yellow colour, and cephalic sculpture that is weak to vestigial. They all have relatively long scapes (SI 115-158), a head that averages relatively narrow (CI 75-84), and long metafemora (MfL/HW 1.25-1.50). Morphologically, these three species are strikingly similar, but their workers can be separated by their relative dimensions, as discussed under
