This species is known from four nearby localities at the southern end of Lake Tanganyika: Kitungulu (Tanzania); Tatanda (Tanzania); Kalambo Falls (Zambia); and Mbala (Zambia). An additional record from Kabanga, Tanzania near the Burundi border was collected in 2007 (A. Channing pers. comm. November 2015). However, surveys in nearby regions (Southern Highlands, Katavi National Park and Mahale) have not recorded this species. This region is poorly surveyed, so the extent of this species' range is unknown and it may occur in other localities. Its extent of occurrence (EOO) is 8,205 km2.
Habitat and Ecology
There is very little information on its habitat and ecology. It was originally found in a remnant of rainforest and has more recently been found in woodland. As with other congeners, it is presumed to breed by larval development.
There is no information on the population status of this species, and only a few specimens are known (see Poynton et al. 2005). However, if it relies on forest habitat declines may be ocurring in the population due to ongoing loss of habitat quality and extent.
There is ongoing decline in the quality and extent of forested habitats throughout the region in which the species is found due to agricultural activities, wood extraction, and expansion of human settlement. However, human population density here is lower than other places in East Africa, so these threats may be less severe.
It is not known from any protected areas.
Careful management and some protection is required for forested habitats in this region.
More information is needed on this species' distribution, population status, natural history and threats.
Red List Status
Listed as Vulnerable due to its extent of occurrence (EOO) of 8,205 km2 constituted of two threat-defined locations, and ongoing decline in the quality and extent of its habitat.
This species was under the generic name Amietophrynus but is now treated under Sclerophrys (Frost 2016).
This is an amended assessment created to account for the change in generic name.
