Worker
Bolton (1982) - TL 2.3-2.5, HL 0.60-0.62, HW 0.49-0.50, CI 81-82, SL 0.34-0.35, SI 69-70, PW 0.35-0.36, AL 0.66-0.68 (2 measured).

Mandibles extremely finely and delicately superficially shagreened, almost smooth. Median portion of clypeus with anterior margin evenly arcuate-convex, with a narrow cuticular apron. Median clypeal carina vestigial to absent. Frontal carinae and antennal scrobes absent, the scapes short. Maximum diameter of eye 0.12-0.13, about 0.24-0.26 x HW and with 7-8 ommatidia in the longest row. With the head in full-face view the sides narrower in front of the eyes than behind and somewhat convergent anteriorly. Behind the eyes the sides very slightly convex and rounding into the occipital corners, the occipital margin itself very feebly impressed medially to almost straight. With the alitrunk in profile the promesonotum shallowly convex, the metanotal groove impressed and the propodeum convex, more strongly so than the promesonotum. Propodeal spines broadly triangular and stout, about as long as their basal width. Propodeal declivity concave between the spines and the rounded low metapleural lobes. In dorsal view the alitrunk with the pronotal shoulders obtusely and bluntly rounded, the promesonotum narrowing to the metanotal groove. Behind this the sides of the propodeum diverge to about the level of the spiracle, pass through an obtuse angle and then converge again to the bases of the spines. Petiole in dorsal view with a tubercle at either side of the node and the posterior margin of the node with a much smaller and inconspicuous pair of tubercles. Petiole in profile with a short anterior peduncle which has a small triangular process ventrally. Dorsal surfaces of head, alitrunk, petiole and postpetiole finely densely sharply reticulate-punctate, the promesonotum and head also with traces of fine rugular sculpture. First gastral tergite basally with very delicate superficial shagreening. All dorsal surfaces of head and body with numerous very short blunt hairs; legs and scapes without standing hairs. Colour uniform yellow.
