RV 2043. Australia, Queensland, E of Brisbane, Cape Moreton; dredged, depth 46.8 m. Scale bar is 1 cm.
The intra-specific variability of this species almost seems absent. It is highly recogniseable and should only be compared to Ancillaria cingulata Sowerby, 1830, which is congeneric and which was considered to be synonymous with, or to be a subspecies of the present taxon. The latter taxon remains somewhat smaller, is more slender, and lacks the prominent chestnut supra-sutural coloration starting at the posterior end of the aperture. Furthermore, it has a more western and northern distribution.
