Diameter of annulus of propodeal spiracle usually greater than the thickness of the propodeal spine at its midlength. Petiole node in profile more or less erect with respect to the peduncle, the node not obviously inclined posteriorly; node often with a defined posterior surface that is differentiated from the oblique dorsum, but in some the dorsum rounded. Sculpture of petiole node conspicuous: in profile with distinct costulae or rugulae that ascend the anterior surface, travserse the sides near the dorsum, and usually overlap onto the posterior surface; in some specimens the costulae extend across the posterior surface. Height of petiole node in posterior view (from midpoint of the dorsal margin of the foramen to the apex) 0.86-1.00 x its maximum width. In dorsal view postpetiole 1.10-1.18 x broader than long; maximum width of postpetiole <1.20 x the length of a propodeal spine; maximum width of postpetiole 0.93-1.07 x the distance between the apices of the propodeal spines. Length of postpetiole node in profile about equal to the height of the segment. Dorsum of postpetiole with weak punctulate sculpture over most or all of the surface, and laterodorsally with longitudinal costulae visible. Full adult colour yellow.</paragraph>

QUEEN (gyne). Ergatoid only known (e.g. CASENT0192035). The single ergatoid specimen available is almost exactly like the worker, but retains a small median ocellus, and is larger than most workers, HL 0.77, HW 0.64, CI 83, SL 0.54, PW 0.49, WL 1.00, MfL 0.68 (1 measured). The relative dimensions of the eye, petiole, and postpetiole are as in the worker. It is possible that the two largest individuals regarded as workers here (HL 0.74-0.76, HW 0.60-0.64, MfL 0.66-0.70) may in fact be ergatoids in which the ocelli are wholly supressed. MfL in these two specimens is decidedly above the range shown otherwise, which is MfL 0.55-0.58. If so, this would parallel the situation seen in
