Justification: Although this skate is apparently rare and likely endemic to the west coast of Africa, most specimens have been caught at depths >700 m during research sampling. Thus commercial trawling is not likely to be impacting this species at present. However, the situation must be re-evaluated as trawl operations expand into deeper waters. Further research on life history of this poorly known species is also required. |

| Population: | Rarely recorded from the slope but size of population unknown, and rarity may be an artifact of limited deeper water sampling in the region to date. |
| Population Trend: |
Unknown
|
| Habitat and Ecology: | A deep slope species, with most specimens taken deeper than 700 m. Nothing is known of the species? biology. Maximum size is >60 cm total length (TL), >36 cm disc width (DW) (Hulley 1988). |
| Systems: | Marine |
| Major Threat(s): | Expansion of deep demersal trawl fisheries in the region. The species is not utilised. |
| Conservation Actions: | No conservation measures in place for this species. Research into life history and the monitoring of bycatch in any expanding deep-water fisheries is required. |
