The collared carpetshark is a poorly understood species of carpetshark of the family Parascylliidae endemic to the waters of eastern Australia between latitudes 26°S and 38°S. It is typically found 55–128 m (180–420 ft) in depth near the floor of rocky reefs on the continental shelf, though its depth range can extend between 20 and 230 m.
