Description
Worker major Length 7.4-7.6 mm. Much smaller, than discors For. and even like the augustinota For. The head is also much narrower and longer. Mandibles with 7 teeth. Thorax more weakly and evenly convex as with discors. The node lower and thicker. The tibia have no trace of barbs on them and are thinner. The body is quite smooth and glossy, only very weakly and finely wrinkled. The back of the head is only very weakly concave. The scape extends beyond the posterior margin of the head by more than a quarter, almost a third of its length. No trace of upstanding or flat lying hair is visible on the legs and scapes as with discors. The upstanding covering of hair is very sparse on the body, several hairs on the clypeus and cheeks. The flat lying pubescence is very sparse throughout, brownish yellow, limbs reddish yellow. Worker minor Length 4.9-6 mm. The head is 1.5 times longer than wide, weakly convex sides, somewhat narrowed in front and behind, somewhat more behind than in front, with a distinct, even somewhat edged posterior margin. Eyes only a little behind the middle. The lobe of the clypeus forms a right angle, as with the major worker; the clypeus has only a suggestion of a keel. The scape extends over the back of the head by more than half its length. Quite bright reddish yellow with a light brownish gaster. Yarrabah, Malanda (Queensland). The head of the specimen from Malanda (worker minor) has a distinct posterior margin, as the one from Yarraba.
