Description
Workers 7 to 10mm Major worker. Clypeus subcarined,lobe short and trapezoidal. Mandibles punctate, with a few striations. The head in the case of the major is almost as wide and convex as testaceipes of which it has the same form. A close neighbor of walkeri from which it differs especially by the presence of a lobe on the clypeus. The middle and posterior tibias have a range of strong spines. Pilosity is very sparse. The tibias and scapes are without erect hairs. The metanotum (= propodeum) has, as it were, 3 faces separated indistinctly by curves: a short basal face, then a median face in profile concave in the middle in the case of the major worker, then the declivity. The pronotum, mesonotum and basal face of the metanotum (= propodeum) form together a strong convexity. The node is of moderate thickness. Glossy and weakly shagreen. The head, except the occipital angles, the mesonotum and matanotum are a dark chestnut brown; the abdomen except the base and the occipital angles are a lighter brown; pronotum, node, tarses and antennae yellowish red; the rest of the limbs and the base of the gaster just as the front of the head in the minor worker, pale yellow. The minor worker has a rectangular head with a very distinct posterior border and it has very large eyes. Pera Bore, N.S.Wales (Froggatt) This group constitute a transition from the group maculatus to the Australian group testaceipes, walkeri etc.
