, and morphological examination reveals an uncomfortable array of variation, if this is to be considered a single species. Limited DNA analysis also reveals wide variation in several samples examined. Aside from the fact that the colour of the body can vary from very pale, depigmented yellow all the way through to coal-black, there are considerable differences in the size of the eyes (which can vary from medium-sized and slightly asymmetrical to enormous and protuberant), the length of the antennal scape (from extending to just beyond the posterior margin of the head to extending by at least half its length beyond that margin) and the shape of the propodeum (which varies from broadly protuberant to long and dorsally flattened). Relatively distinctive forms can be found in certain regions; for example, workers collected in the south-west of the continent tend to be pale and very small with narrow head and small eyes, whereas many taken from the mid-west of

. Perhaps the most spectacular morph is one collected from a variety of sites, but generally inland. This ant is honey-coloured, with very elongate scapes, large eyes and a flattened propodeum. However, none of these forms possesses discrete characters that enable it to be recognised as a unique taxon when all populations are considered: that is, intermediate forms connect the clusters of the more distinctive workers, and hours of examination have failed to identify diagnostic features unique to a particular morph. As a consequence, the position taken here is that

is genuinely polymorphic with respect to phenotype and also genetically variable. This position could change, if further molecular analysis reveals unacceptable genetic distance between given populations. However, if such is the case, then workers of the constituent species would have to be regarded as truly cryptic and possibly impervious to separation using morphological characters. For the present, the distinctly asymmetrical eyes placed near the margin of the head in full-face view, the oblique angle between the dorsal and declivitous propodeal surfaces, and the lack of erect or subdecumbent setae on the hind tibiae, sides of head and antennal scape serve to identify the species as understood here.
