Non-type: SAIAB 11125.  South African distribution: Port Shepstone north to KZN border with Mozambique.   Remarks: Accounts by Wallace (1967b, see fig. 15) and Compagno et al. (1989, see illustration on p. 79) described a  Rhinobatos annulatus“Natal” form that was distinguished by large brown spots from the “Cape” form. However, the “Natal” form is actually  Rhinobatos austini, while the “Cape” form, which is now assigned to the genus  Acroteriobatus, has numerous small eyespots on its dorsal surface. Furthermore, the recently described  R. austiniwas also misidentified with  R. holcorhynchusdue to both species having a black teardrop-shaped blotch on the ventral surface of its snout. Recent re-examination of specimens from Mozambiqueand Madagascarhas expanded the known range of  R. austini. This species appears to inhabit a mostly coastal habitat from inshore to 107 m, but mostly less than 75 mdepth, while  R. holcorhynchusappears to occur in deeper water at depths from 75 mto at least 350 m( Séret et al., 2016a; Ebert & Gon, 2017). The illustration in the species account of  R. holcorhynchusin Séret et al. (2016a, see fig. 10.20) is actually  R. austini.  Conservation status: DD (2019). 3072574306 [373,640,1364,1391] SAIAB South Africa -30.833334 Near Port Shepstone 1219 30.483334 Port Shepstone 75 76 SAIAB 75223 1 KwaZulu-Natal holotype 3072574672 SAIAB South Africa South Africa 75 76 SAIAB 75223, SAIAB 186420, SAIAB 193574, SAIAB 11125 2 holotype
