This species is known only from São Tomé and Rolas Island, in São Tomé and Príncipe. It occurs from sea level to at least 1,300m asl. It appears to be absent from the drier northern part of the island. There is an unconfirmed report of this species from "Upper Zire", which is likely to refer to another species.
Habitat and Ecology
It lives in soil in all habitats on São Tomé (except dry areas in the north), including coconut plantations, forests, trash piles, sugar cane, degraded areas, rocky areas, and totally denuded land coastal. It is a viviparous species, and is not dependent on water for breeding.
Recent information suggests that it is an abundant species.
It appears not to be a threatened species. It has appeared in the pet trade in the 1990s, but not at a level to constitute a threat to the species.
It occurs in Obo National Park.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although its Extent of Occurrence is much less than 5,000km2, it is common, adaptable, and does not appear to be in decline.
An unconfirmed report of this species has come from "Upper Zaire".
