Geographic Range [top]

Range Description:This species orignally recorded from a single swamp in the Udzungwa Scarp Forest Reserve at 1,740 m asl in the Udzungwa Mountains in eastern Tanzania. Surveys conducted between 2013-2015 in the Udzungwa Scarp have found it to be widespread above 1,700 m asl. Its extent of occurrence (EOO) is 171 km2 and is constituted of fewer than fived threat-defined locations.

Population [top]

Population:It is relatively common within its range.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It restricted to swamps in dense montane forest where it breeds by larval development; eggs are laid close to the water on leaves in the swamp.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The main threat to the species is habitat loss caused by agricultural encroachment and small-scale wood extraction.

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in the Udzungwa Scarp Forest Reserve and is the subject of a monitoring program (M. Menegon pers. comm. October 2015). Protection of critical habitat is expected to improve as the Forest Reserve will become a Nature Reserve, which should reduce encroachment (S. Loader pers. comm. October 2015).

Conservation Needed
Ongoing and improved protection of the species habitat is required.

Research Needed
Further research is required to clairfy the species' distribution, population status and additional threats information.
