The 1994 geographical argument, while based on confirmed contemporary distribution patterns, failed to acknowledge that the purported hybridization event likely occurred at least hundreds of thousands, or more probably more than a million years ago; that very different distribution patterns on a geographically and environmentally different terrestrial substrate would have prevailed and that chromosomal rearrangements could have occurred subsequently.

There is no sound current morphological evidence of gene introgression between these taxa in Victoria, or evidence that they hybridize in the area of range overlap, and on these grounds it could be concluded that they represent separate, related, reproductively isolated, apparently parapatrically distributed, but previously allopatrically evolved, sister species. Their separate distinctive karyologies could support this conclusion. However, several known series of specimens from the Melbourne area are believed to evidence colonies containing workers representative of both forms (though the specimen labels do not specify the defining collection circumstances). Such “mixed” colonies are frequent and well confirmed in collections from Tasmania, where their presence was considered by Imai, Taylor

, rather than separate, putatively reproductively-isolated species. The present argument would presumably apply even if mixed colonies are not present in Victoria, in light of the Tasmanian evidence for crossing with introgression—though it is entirely plausible that two parapatrically distributed species/semispecies could experience introgression in some populations but not in others.
