This species ranges from Bagandou, Etoi and Bouchia in southern Central African Republic, east to northeastern Democratic Republic of the Congo as far as Semliki in western Uganda. It was recently also confirmed from Batéké Plateau National Park, Gabon (Zimkus and Larson 2012). This represents the first confirmed country record in Gabon, extending the range of this species over 750 km SW from the holotype locality in Bouchia, Central African Republic. It presumably occurs in northern Congo, but this has not yet been confirmed.
Habitat and Ecology
It is a water-dependent species found in small water holes, pools and shady swamps in lowland forest. It is clearly adaptable, since it has also been found in swamps at the edge of a village. It breeds in still water. In Bouchia it is sympatric with X. andrei, X. fischbergi and S. epitropicalis.
It is abundant in suitable habitat and the population is believed to be stable.
In view of its wide distribution and likely adaptability to altered habitats, this species is unlikely to be seriously threatened. It is harvested for human consumption, and this might have an impact on local populations.
This species occurs in Batéké Plateau National Park in Gabon (Zimkus and Larson 2012), and may occur in the Garamba and Virunga National Parks in Democratic Republic of Congo.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although it is seldom recorded, it has a relatively wide distribution, is tolerant of a degree of habitat modification and has a presumed large population.
This species is a diploid species in the Xenopus fraseri Group (Loumont, 1986).
