Description
Length 4-7 mm. Worker major. A close neighbor of yerburyi Forel of Ceylon, but head is distinctly narrower in front, shorter and wider behind; mandibles are bigger. The coarse pits at the front of the head are stronger, more abundant and extend to the eyes and on part of the front. Head is excavated behind, the scape, which scarcely reaches the occiput in yerburyi, exceeds it slightly in mackayensis. Mesonotum is not weakly bordered; it is followed by an intermediate segment in a the form of a transverse round swelling which is lacking in yerburyi. The basal face is wider and shorter and hollowed out into a saddle at least as much as in yerburyi. The segments of the gaster have a wide rim of brilliant golden yellow. Thorax is much more convex from front to back. Gaster silky (glistening), sculpture very fine and very dense (striate or wrinkled transversely) otherwise the sculpture is like yerburyi. Pilosity a little more sparse, no where on the tibias. Anterior half of the head,funicles and base of the scapes a testaceous light red; the rest is black, with limbs and the other half of the scapes brown. Worker minor. The head is wider behind than yerburyi; basal face of the metanotum(= propodeum) is wide, profoundly excavated in a saddle. Mesonotum with a margin. The anterior border of the basal face is raised up, which forms a slight meso-metanotal indentation which does not exist with yerburyi. Mandibles and front of the clypeus are the only reddish parts of the head. Otherwise like the major worker. Mackay, Queensland (Turner)
