Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2004

Justification:
An uncommon endemic species rarely sampled from the shelf edge and slope (253 to 761 m) in its known range from central Mozambique to South Africa. Considered Data Deficient because virtually nothing is known about this skate, which is recorded from only a few specimens. It may, however, be affected by trawling and longline fisheries. This species may be found to be more widespread in deeper waters when these are surveyed more thoroughly in the future, in which case further evaluation will be required.
