Justification | Antimima loganii is a poorly known and apparently rare species. Its distribution range is not well known, but occurrence records suggest that it is very small. There is currently one known location, but it is likely an underestimate, as it may be overlooked due to taxonomic uncertainty. It is potentially threatened by overgrazing, and is therefore listed as Vulnerable under criteria D2. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | This species is endemic to Roggeveld Escarpment near Sutherland in the Northern Cape of South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Roggeveld Shale Renosterveld |
Description | It occurs in crevices of sandstone rocks. |
Threats |
| There is ongoing degradation in large parts of the Roggeveld Escarpment due to overgrazing and drought. Field observations of one recently recorded subpopulation did not note grazing impacts, but this subpopulation is potentially vulnerable to increases in grazing pressure. |
Population |
This species is a rare and poorly known species. The type specimen was collected at an unspecified locality near Sutherland, and there is one recent, unconfirmed record from the same area. It may be overlooked due to taxonomic confusion within Antimima, which is in need of taxonomic revision. The population size, structure and trend is not known.
|
Population trend | Unknown |
Notes |
| Antimima is in need of taxonomic revision, with many species that are poorly known due to difficulties in distinguishing them from other closely related species. |
