Description
Worker minor Length 5.5-5.7 mm. A little smaller than the type oetkeri. Mandibles armed with 5 teeth glossy and punctate. Clypeus with an arched anterior lobe, a little trapezoidal, with a median keel. The head is a good fifth or quarter longer than wide, more narrow than the type, sides more distinctly compressed, much less convex and the posterior border is straight and not concave (which demonstrates that with my types of oetkeri of which the posterior border is concave are not genuine minor workers). Eyes are a little smaller more convex. The scapes exceed the posterior border of the head by 2/5 of their length. The thorax has the exact form of oetkeri, but its dorsum is a little less convex, and the angle between the basal face and the declivity is more marked, though rounded. The epinotum is as high and like a blade is as compressed as the type. Node is a little different, as thick at the bottom but not sharp at the summit, a little more convex in front and almost flat behind. Subopaque, densely and a little less finely reticulate compared with the type. Gaster glossy, feebly shagreen. The body is covered with an erect pilosity yellowish and quite abundant,also on the cheeks, pilosity is almost lacking in the type. Limbs have a distinct obliquely raised pubescence like evae but a little weaker. The tibias have small spines almost like the type. Black; mandibles,antennae and limbs red. Tasmania. (Lea) This form is quite embarrassing. It is completely different from evae and lownei by the form of the head which is much longer, by its epinotum which is higher, and by its sculpture; but apart from that it closely resembles evae. Much smaller than michaelseni much more hairy than it with shorter scape, it resembles it a little by the form of the thorax of which the angle is only a little less sharp. I am placing it provisionally with the race oetkeri while waiting until one recognizes or finds the major worker. Perhaps it is a different species.
