Description
Worker
Holotype. TL 3.1, HL 0.72, HW 0.64, CI 89, SL 0.58, SI 90, PW 0.50, AL 0.90.
Mandibles striate; anterior clypeal margin entire and convex, the anterior apron or flange narrow and inconspicuous. Frontal carinae extending back beyond the level of the eyes but no more strongly developed than the rugular sculpture of the cephalic dorsum, the carinae fading and becoming inseparable from the remaining cephalic sculpture before reaching the occiput. Impressions of antennal scrobes shallow, only feebly developed. Eyes of moderate size, maximum diameter C. 0.14, about 0.22 x HW. Occipital margin shallowly concave in full-face view. Pronotal corners in dorsal view very broadly rounded. Propodeal spines short, about as long as the meta pleural lobes, the spines themselves narrow and acute, slightly elevated; metapleural lobes broadly triangular. Petiole in profile with a narrow, downcurved anterior peduncle, the node shaped as in figure. Petiole node in dorsal view slightly broader than long. Dorsum of head strongly rugulose, the rugulae irregular and meandering, with numerous cross-meshes; occipital region with a disorganized ruguloreticulum. Dorsum of alitrunk reticulate-rugulose. Sides of petiole and postpetiole sculptured and the dorsal surfaces of these segments with traces of sculpture which are better developed on the petiole than the postpetiole. Gaster unsculptured. All dorsal surfaces of head and body with numerous fine hairs of varying length but antennal scapes only with quite dense, short pubescence of about uniform length. Dorsal (outer) surfaces of hind tibiae equipped with a dense coat of short hairs which are erect, suberect or subdecumbent. Colour uniform blackish brown, the appendages pale yellow-brown.
Paratypes. As holotype but showing variation in thickness and length of propodeal spines. In some the spines are slightly longer than the metapleural lobes, in others distinctly shorter. In one specimen the spines are almost as broad basally as they are long, whereas in the others the spines are obviously longer than their basal width. Postpetiole is almost unsculptured in some individuals. Range of dimensions of paratype workers: TL 2.9-3.2, HL 0.68-0.72, HW 0.58-0.64, CI 84-89, SL 0.52-0.58, SI 87-93, PW 0.46-0.52, AL 0.84-0.90 (10 measured). Maximum diameter of eye C. 0.13-0.14, about 0.22-0.24 x HW.
