From the IUCN Red List Species Account:


Range Description

This species ranges from Rwanda and Burundi, through eastern and southeastern Democratic Republic of Congo, southern Tanzania, Malawi, Zambia, central Mozambique, Zimbabwe and Angola. The specimens from northern South Africa previously assigned to this species are thought to in fact be Ptychadena porosissima. It is an upland species, occurring at 800-2,300 m asl.

Habitat and Ecology

It is a species of medium- to high-altitude grasslands, in the vicinity of pools, seepages, dambos and permanent sponges, where it presumably breeds. The males call from shallow water. Its adaptability to altered habitats is not known.


It is believed to be reasonably common in suitable habitat. There are no recent confirmed records from South Africa, and the continued existence of this isolated population should be investigated.

Population Trend


Major Threats

There is very little information, but it is widely distributed in a region of low human impact, and so it is unlikely to be significantly threatened, except in local situations.

Conservation Actions

It occurs in many protected areas, including the Upemba National Park in the Democratic Republic of Congo.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution and its presumed large population.
