From the IUCN Red List Species Account:


Range Description

This species is known from isolated records from southern Cameroon, southern Congo, and eastern Democratic Republic of Congo. The type locality is an unspecified locality in Cameroon; there are more recent Cameroonian records attributed to this species from Mount Manenguba and from Mount Nkolodon near Yaounde. In eastern Democratic Republic of Congo, there are records from Virunga National Park (Laurent 1972) and from the town of Beni. Its occurrence in Gabon, Equatorial Guinea, and Central African Republic is not confirmed; attempts to map its distribution for this assessment however assume that it is found in the intervening areas between the known localities, in the forest zone north of the Congo River. However, Amiet (pers. comm.) points out that Arthroleptis tuberosus, when better understood, might prove to be a montane species, in which case the attempts made at mapping its range so far are clearly wrong. In any case, the specimens from eastern Democratic Republic of Congo were never found in the field, and so their assignation to A. tuberosus is doubtful. It is also possible that animals from Cameroon currently referred to as A. adelphus are in fact A. tuberosus. The confusion surrounding this species will only be resolved by more fieldwork in the central African rainforests, with a particular focus on its calls.

Habitat and Ecology

This is presumably a forest species, living on the forest floor in montane and perhaps lowland forests, which presumably breeds by direct development.


There is no information on its population status, pending clarification of its taxonomic status.

Population Trend


Major Threats

It is expected to be declining because of forest loss due to agricultural development and logging.

Conservation Actions

This species is said to occur in Virunga National Park and probably also in other protected areas.

Taxonomic Notes

There are major taxonomic problems with the genus Arthroleptis through much of Africa. In many cases, the available names can be referred only to museum specimens, not to animals in the field. This is because the identification of these species frequently depends more on their vocalizations than their morphology. The specimens currently referred to as Arthroleptis adelphus might possibly belong to this species (J.-L. Amiet pers. comm.).
