The smallest species of the genus Rajella in this region (58 cm total length (TL), 32 cm disc width (DW)), this skate is endemic to Southern Africa (Namibia and South Africa) in 310 to 520 m, occurring most commonly in areas heavily trawled for hake off the west coast of South Africa. Although there are no data on population size or trends, research trawl surveys indicate it is uncommon. This together with heavy fishing pressure in much of its known range leads this skate to be assessed as Near Threatened with a need for further information on life history, population status and details of specific threats.
