Description

Worker

Holotype. TL 2.7, HL 0.60, HW 0.54, CI 90, SL 0.40, SI 74, PW 0.42, AL 0.72.

Mandibles striate, anterior clypeal margin arcuate and entire, with a narrow but quite conspicuous anterior apron or flange. Frontal carinae weakly developed, only slightly stronger than the cephalic longitudinal sculpture, but extending back well beyond the posterior margins of the eyes and forming the dorsal margins of the shallow but broad antennal scrobes. Maximum diameter of eye c. 0.16, about 0.29 x HW. Propodeal spines short, stout and straight, only slightly longer than the broad, triangular metapleural lobes. Peduncle of petiole downcurved, the node narrowing from base to apex in profile and with the dorsal surface about as long as the tergal portion of the node is high. In dorsal view the petiole node about as broad as long, slightly broader behind than in front. Dorsum of head with irregular, feeble longitudinal rugulae to the level of the posterior margins of the eyes but behind this cross-meshes become numerous and a reticulum is present on the occiput. Ground sculpture of superficial punctulation is quite conspicuous and on the whole the cephalic sculpture has a disorganized appearance. Dorsal alitrunk with a rugoreticulum, the components of which are low and blunted on the promesonotum. Petiole dorsally with weak but fairly conspicuous rugulae present, the postpetiole and gaster unsculptured. All dorsal surfaces of head and body with numerous fine erect or suberect hairs. Antennal scapes with a spaced row of long hairs projecting dorsally and dorsal (outer) faces of hind tibiae with numerous stout erect or suberect hairs. Colour uniform blackish brown, the legs yellowish brown.

Paratype. As holotype but slightly lighter in colour, uniform dark brown, with measurements TL 2.6, HL 0.60, HW 0.56, CI 93, SL 0.40, SI 71, PW 0.42, AL 0.72. Maximum diameter of eye c. 0.16.
