South African distribution:?Endemic. Confirmed along the west coast from at least Langebaan (WC) to off the Transkei coast (EC) and possibly to central KZN, but records from outside this region should be carefully checked.
Remarks: The range for A. annulatus is poorly defined since it has frequently been misidentified with other South African guitarfish species, including A. blochii , A. leucospilus , A. ocellatus , and R. austini . In addition, records of this species outside South Africa also require confirmation. The species may eventually prove to be a South African endemic.
Conservation status: VU (2020).
