National Status |
Status and Criteria | Least Concern |
Assessment Date | 2014/07/24 |
Assessor(s) | L. von Staden |
Justification | Although rarely recorded in South Africa, it is likely to be overlooked, and not in danger of extinction. It is widespread outside of South Africa. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Northern Cape |
Range | Coastal areas of Angola and Namibia and southwards to the Richtersveld, Northern Cape, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Desert, Succulent Karoo |
Description | Dunes, mountain slopes and dry riverbeds. |
Threats |
| This species is possibly threatened by habitat loss and degradation due to mining and overgrazing, but these threats only impact over a small proportion of its range, and is unlikely to lead to its extinction. |
Population |
This species has been rarely recorded in South Africa, but is suspected to be overlooked, as it occurs in a remote and poorly explored area, much of which is difficult to access due to diamond mining restrictions.
|
Population trend | Stable |
Notes |
| Norlindh (1943) cites a collection from Langebaan in the Western Cape, a disjunction of around 500 km from the nearest other records of this species. It has never since been relocated in this well-collected area, nor anywhere in between, and it is assumed that this record was mislabelled, or represents another taxon. |
