This species is known only from Mossamedes District in south-western Angola, although its range is largely unknown.
Habitat and Ecology
It is associated with granitic inselbergs in dry, sandy areas. Its breeding habits are unknown, but reproduction presumably takes place in water.
There is very little information on its population status, and only a few specimens are known, presumably because of lack of herpetological survey work within its range.
There is no direct information on threats to this species.
Its presence has not been confirmed in any protected areas, but it is likely to occur in Iona National Park. Research is needed into the distribution and population status, ecology, use and trade, and threats.
