Justification:
Listed as Vulnerable because its extent of occurrence (EOO) is estimated to be 9,073 km2, it is known from two threat-defined locations, and there is continuing decline in the extent and quality of its habitat in the Udzungwa Mountains.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is endemic to the Udzungwa Mountains in southern Tanzania where it is known from two localities: Dabaga and Uzungwa Scarp. However, this is a poorly surveyed area and the species' distribution in these grasslands is poorly understood, so the current range map reflects its likely occurrence throughout this area. It occurs between 1,300 and 2,050 m asl and its extent of ocurrence (EOO) has been estimated as 9,073 km2. This species has two threat-defined locations, one of which is threatened by pine afforestation in the grasslands, and the other is threatened with forest disturbance.

Population [top]

Population:It is moderately abundant in suitable habitats.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It is a species of marshy areas in open montane grasslands, and from grassy glades in forest/grassland mosaic. It has been found in pastureland, but it is not clear that in can survive in croplands. As with other congeners it is expected to breed by larval development.
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): Its montane grassland habitat is threatened by afforestation, agricultural expansion, fire, and expanding human settlement.

Conservation Actions [top]

Conservation Actions: Conservation Actions
It is not known from any protected areas.

Conservation Needed
Improved site and grassland habitat protection and management are needed.

Research Needed
Further research is needed on the species distribution, population and taxonomy.
