From the IUCN Red List Species Account:

 

Range Description

This species is known from a single locality in the Sakara Nyumo Forest Reserve in the Livingstone Mountains, at 2010 m asl, in southern Tanzania. Surveys in the Madenge and Mdandu Forest Reserves failed to record the species, so further sampling in the Livingstone Mountains and across the Southern Highland region is required to establish whether it occurs more widely (Loader et al. 2015). Its present extent of occurrence (EOO) is 28 km2.

Habitat and Ecology

This arboreal species occurs in high elevation swamps surrounded by montane rainforest, but it was never found in completely open habitat  (Loader et al. forthcoming (2015)). It is presumed to breed by larval development.

Population

Very little is known about this species' abundance; surveys in 2011 collected 14 specimens at the only known locality  (Loader et al. 2015). However, due to ongoing habitat loss, the species population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

There is continuing loss of its habitat due to the expansion of agriculture, wood extraction, and human settlements.

Conservation Actions

Conservation Actions
It occurs in the Sakara Nyumo Forest Reserve which offers limited protection of its forest habitat.

Conservation Needed
Ongoing protection of its habitat is required.

Research Needed
Further research is needed on the species' population size, distribution and trends, and monitoring of the species population to establish its stability in its small range and in light of ongoing habitat loss.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered as its extent of occurrence (EOO) is limited to 28 km2, it is known from a single threat-defined location, and there is ongoing decline in the quality and extent of its habitat in the Livingstone Mountains of Tanzania.
