As part of my ongoing studies of the Callianassidae, Dr G. Poore of the Museum of Victoria, Australia, sent me four small specimens from Tasmania. These specimens, which include two ovigerous females, are closely allied to Callianassa lewtonae from the northern Great Barrier Reef, Queensland, Australia. They differ from that species because the merus of the chelipeds bears a triangular ventral lobe in the larger cheliped and a sharp ventral spine in the smaller cheliped; and the antennular peduncle is much longer than the antennal peduncle. Only Callianassa ceramica, C. arenosa, and C. australiensis have been previously recorded from Tasmanian waters.
