Description
Worker major. Length, 8.3 mm. Mandibles and anterior border of head black or brownish black; clypeus dark reddish brown; frontal carinae black; insertions of scapes reddish yellow; antennae dark brown with the tip of the funiculus lighter; head thorax and node dull blood red, the epinotum is darker, more brownish; legs reddish brown with tibiae and tarsi darker; first segment of the gaster red, second brownish red, rest of gaster brown. Mandibles with scattered elongated punctures; clypeus finely, densely reticulate punctate; head very finely and densely striate transversely. he striae are joined together to form a wide meshed reticulation. Thorax is striate punctate, on pronotum more transversely arched, and coarser on the meso-epinotum; node transversely finely striated; gaster transversely striate. Hair long, erect, reddish, abundant on mandibles, epinotum, node, gaster. Head slightly longer than broad, with the sides almost straight, and the occipital border straight, corners abrupt. Mandibles thick triangular, with five strong teeth; clypeus large, not carinate, the anterior border rounded and furnished with two large blunt teeth in front; frontal area small, rhomboidal; frontal carinae elevated, very distinct and diverging behind; frontal groove distinct. Scape extends to the posterior border of the head. Eyes moderately large, flat, are placed at the posterior third. Ocelli lacking but there is a pit in place of anterior ocellus. Thorax nearly twice as long as the broadest part which is the pronotum; pronotum nearly twice as broad as long, rounded in front and with feebly convex sides. The promesonotal suture is black and very distinct. Meso-epinotal suture very faint. Meso-epinotum is nearly twice as long as broad in front, narrowed so that it is about a quarter as broad behind as in front. In profile the dorsum of the thorax is flatly convex with the epinotal declivity slightly concave. Node very transverse, from above it presents a very narrow surface. In profile nearly three as high as long, with slightly convex anterior face, which meets the vertical, straight posterior face in a sharp point. Gaster oval. Legs moderately long and strong. Worker minor. Length, 5.1 mm. Color much more brownish and there is considerable variation. Often the posterior part of the head is black, and the dark area varies in extent. The node and legs in some species are very dark brown. Sculpture similar to that of major. The hair is much more noticeable on the thorax, more abundant on the whole body than in case of major. Head as broad as long, slightly broader behind than in front, with the sides and the posterior border almost straight. There are no noticeable teeth on the anterior border of clypeus and the teeth of the mandibles are longer and sharper. The eyes are larger, more convex, placed at the posterior corners of the head. The scape is longer, extending beyond the occiput by half its length. The thorax like that of major, but the pronotum is relatively broader, the meso-epinotum longer and more tapering, appearing to end in a point. the node is thicker in profile, about twice as high as long. Rest as in major. Collected by F. Heigel. Material examined: Twenty minor workers and a major worker. This species is nearest to C. sponsorum Forel, but is larger and different in color. The node of the major is much thinner, the clypeus is more rounded in front and the eyes placed further back. Type locality: Broome, N.W. Australia. Type: Holotype worker major in collection at CSIRO, Canberra.
