mind the curve of a snail shell. Only the minor worker has so far been recognized. All records have come from WA, where it appears occasionally in collections from the Kimberley and Pilbara region on the mainland and from Barrow Island, but the species is also likely to occur in the NT. The ecology of this ant is not known. Attempts to sequence its DNA have achieved only limited success with only the wingless gene successfully amplifying. Its closest relation is
