This species is known mainly from highland areas in northern Tanzania and southern Kenya (including the Serengeti National Park, Nairobi, Mau Narok and the Kinangop Plateau), but its range is very poorly known. There are also records from Kitende in Uganda and the Marungu Plateau in southeastern Democratic Republic of Congo. It probably occurs at least between 1,200 and 2,500 m asl. Further work is needed to determine the range of this species.
Habitat and Ecology
It is a species of grasslands (including montane grassland) and dry savannahs, favouring open areas with short vegetation, and is extremely successful in grassy meadows. It breeds in any shallow water body, including vleis, flooded depressions, drainage ditches, puddles, small pools, inundated grasslands and shallow pans, especially where grass is growing. It is able adapt to human-modified habitats, and is found in the edges of Nairobi, and near the airport where they call in large choruses from roadside ditches (S. Lötters pers. comm.).
It is abundant around the edges of Nairobi (S. Lötters pers. comm.).
If its ecology is similar to that of Cacosternum boettgeri, it is a generalist that is very unlikely to be significantly threatened.
It occurs in the Serengeti National Park, and presumably other protected areas. More work is needed to determine the limits of its distribution, and to determine the relationship between this species and frogs currently assigned to Cacosternum boettgeri from Ethiopia.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its likely wide distribution, probable tolerance of a broad range of habitats and its presumed large population.
We follow Channing et al. (2005) in separating this species from Cacosternum boettgeri.
