Description

Worker. (Probably minor) Mandibles glossy, finely punctate, armed with only 5 teeth. Clypeus keeled, and forms at the front a short rounded lobe. Frontal area rhombiform transversely. Frontal ridges converge at the front and diverge strongly. Scape exceeds the posterior head by 2/5 of its length. Segments 2 to 10 of the funiculus are of almost equal length, the length is almost twice the thickness. Head a perfect trapeze, strongly enlarged behind, the posterior border and the sides straight (the latter almost), with posterior angles almost sharp, hardly rounded; sides are a little compressed. Eyes strongly convex, situated in the posterior quarter. Pronotum almost flat, (feebly convex) with a sharp border in front and at the side and up to the posterior third of the latter, and with the angles rounded. Mesonotum a little convex, with the dorsum like a trapeze, very narrow behind, without an edge. Sutures distinct, but without any grooving. It continues with a weak convex curve of the pronotum and the mesonotum forming at the front a narrow triangular surface, the epinotum is strongly humped, that is to say convex in front and behind and almost sharp between the anterior dorsal triangle of the basal face and the lower narrow triangle of the subvertical sloping face and is much longer than the basal face, which it joins without a boundary from the aforesaid dorsum. Node rather thick, biconvex, almost sharply cut at the side (a little convex behind). Tibias have a row of sharp spines on their internal border; They are cylindrical. Dull; densely and finely reticulate-punctate. Gaster sub-opaque, densely wrinkled-reticulate transversely; Limbs and scapes feebly chagreen, sparsely punctate and rather glossy. The gaster has sparse punctations raised up, piligerous with little bristles beneath. Pilosity erect fine, of a yellow white, sufficiently abundant on the body, of medium length. Scapes and tibias have an pubescence, adpressed on the scapes, oblique or sub erect on the tibias. Pubescence is yellow and very sparse on the body. Black. Limbs,antennae and mandibles brown. Femurs and borders of the mandibles reddish.

Cape York, Northern Australia (Rowland Turner)

About 29 workers but not one major worker. The latter remains to be discovered. A near neighbor of rubiginosus Mayr, from which it differs in color, sculpture, and a much larger epinotum and much more humped (in case of rubiginosus it has a short and triangular basal face and a declivity compressed and sub-vertical). In his description of rubiginosus Mayr forgot to mention the sharp border of the pronotum. C. evae also has a slight relationship with C. arcuatus Mayr.
