Description
Worker major. Length 6.5 to 9 mm. Mandibles short, armed with 6 teeth, the outer border strongly curved, silky, striated, reticulate punctate towards the base. The clypeus without a lobe, without a keel, quite flat, strongly indented in the middle of the anterior border (as in C. marginatus). Frontal area small. Frontal ridges sinuous, strongly diverging. The sides of the clypeus diverge at the front. The head is trapezoidal, quite strongly widened and strongly indented at the back, scarcely longer than its posterior width. The eyes behind the middle. Scapes pass over the occiput by 1/4 to 1/3 of their length. Pronotum depressed, weakly convex, edged in an arc at the front and the anterior part of the sides which make the shoulders very rounded; wider than long. Mesonotum slightly convex, narrow behind, scarcely sub bordered. Basal face of the metanotum (= propodeum) long, narrow, lower at the back, weakly but distinctly concave or in a saddle (much less than ephippium). The declivity is much shorter than the basal face. The node is very thick, as thick at the top as at the bottom, flat at the back, convex in front, quite elevated with the summit convex in all directions. Tibias, cylindrical but slightly channeled, with a range of very short and oblique spines. Very finely and densely reticulate (reticulate-punctate) sub opaque, front of head matte. Gaster with microscopic striations transverse and silky. Pilosity erect, fine, pale yellow, sparse on body, more abundant on the front of the head, distinct on the scapes, none on the tibias. Pubescence extremely short, fine and sparse. Of a yellow rusty red; head and gaster black. Antennae, tarses, and part of the tibias brown. The posterior edges of the segments of the gaster vivid yellow. Worker minor. Head scarcely longer than wide, strongly wider at the back, posterior border almost straight. Clypeus a little more projecting as a rounded lobe but also indented in the middle like the major worker. The scape exceeds the head by 2/5 of its length. Pronotum even more edged and more shouldered than the major worker; mesonotum strongly sub bordered, and its anterior border exceeds by a little the level of the pronotum. In profile the basal face of the metanotum is subrectalinear, without a distinct concavity. In other respects like the major. Bong-Bong, NSW (Froggatt)
