Description

Worker

Holotype. TL 4.5, HL 1.04, HW 0.98, CI 94, SL 0.96, SI 98, PW 0.72, AL 1.22.

Mandibles striate, clypeus with a shallow median impression in the anterior margin. Sides of head evenly shallowly convex, the eyes prominent and quite small, maximum diameter c. 0.20. In full-face view the occipital margin broadly and quite deeply concave. Frontal carinae strongly developed and extending back almost to the occipital margin where they merge into the rest of the sculpture. Antennal scrobes poorly developed, represented by a groove below the frontal carinae which is mostly unsculptured but is considerably shorter than the scape. Pronotal corners angulate in dorsal view. Propodeal spines very long, the metapleural teeth triangular, acute and slightly upcurved. Dorsum of petiole longer than broad, the true dorsal surface a narrow strip as the sides of the petiole are convergent dorsally. In profile the dorsal surface of the petiole is strongly convex and meets the anterior face through a shallow curve so that the two are not separated by an angle. Postpetiole strongly convex dorsally. Head reticulate-rugose, more strongly so posteriorly as anteriorly the cross-meshes tend to be reduced or absent, leaving only the longitudinal component. Dorsal ali trunk reticulate-rugose but more loose and disorganized than on the head, the rugae forming sharp raised ridges. Petiole, post petiole and gaster completely unsculptured, smooth and highly polished. Dorsal surfaces of body with numerous erect or suberect hairs, those on the head and alitrunk longer than those on the gaster. The longest head and ali trunk hairs twice as long as the maximum diameter of the eye. Colour light brown, shining.

Paratypes. As holotype, with a range of: TL 4.0-4.6, HL 0.98-1.06, HW 0.88-0.98, CI 90-95, SL 0.84-0.98, SI 95-100, PW 0.68-0.74, AL 1.14-1.22 (12 measured).
