This species has been known for quite some time to be from extreme western Democratic Republic of Congo, north of the estuary of the Congo River. However, it has also recently been discovered in south-western Gabon in Petit Loango National Park and the Reserve de Faune de la Moukalaba-Dougoua (Burger pers. comm.). It presumably occurs in the intervening parts of Congo and the Cabinda enclave of Angola. In Gabon it has been found from sea level up to 110m asl.
Habitat and Ecology
This species has been found in pristine lowland rainforest, in secondary (but fairly well regenerated) forest, in small forest patches in savannah, and in forest along the savannah-forest ecotone. Its breeding habits are unknown, but assuming that its biology is similar to that of other members of its genus, the eggs are presumably laid in subterranean nests in which the larvae hatch, and from where they subsequently move into permanent and temporary water bodies to develop.
This is probably a common species, but because of its secretive and fossorial habits it is probably often overlooked. Most recent records have been from pitfall traps.
There is very little information on threats to this species, bu the limited available data do not indicate any immediate threats.
It is known from two protected areas in Gabon: Petit Loango National Park and the Reserve de Faune de la Moukalaba-Dougoua.
Red List Status
Data Deficient (DD)
This species is listed as Data Deficient in view of the absence of recent information on its status and ecological requirements, and due to uncertainty as to the limits of its Extent of Occurrence.
