Description
Worker Major or media. Length 8 mm Mandibles short, obtuse, armed with 6 teeth, finely coriaceous, sub opaque, punctate. Clypeus subkeeled, convex, sublobed. Head strongly widened behind, a little wider than long. Thorax quite like C. marginatus but the back is slightly convex; the declivity face of the metanotum (= propodeum) is high, subvertical, forming with the basal face a rounded angle. Basal face scarcely half as long as the declivity. The node almost square, sharp, the superior border weakly indented. 3 or 4 little barbs on the tibias.

Very glossy; very feebly shagreen. Punctation is superimposed much more finely and weakly than C. walkeri, a little stronger on the front of the head than elsewhere.

Pilosity, pubescence and color as with the preceding specimen [walkeri?] but the limbs and scapes are darker and the and the front of the head except for the articulations of the antennae is reddish. East Wallaby Island Western Australia. M. JJ Walker

This specimen, a close relative of the preceding walkeri? is smaller and more glossy, its form is not well determined. However the form of the thorax, clypeus, wider head, and the node prevent me from making it a simple race.
