Listed as Endangered because its extent of occurrence is estimated to be 467 km2, it is considered to occur in four threat-defined locations, its population is considered to be severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in central Eastern Arc region.
Previously published Red List assessments:
2008 Endangered (EN)

Geographic Range [top]

Range Description: This species was described from the Ukaguru Mountains in eastern Tanzania between 1,500 and 1,900 m asl. Surveys have extended its distribution to the Rubeho, Nguu and Nguru Mountains; however, it is considered unlikely to occur much outside of its currently known range (S. Loader pers. comm. June 2012). It is estimated to occur in four threat-defined locations, and taking range as a proxy for extent of occurrence (EOO), this is estimated to be 467 km2.
Countries occurrence:
Tanzania, United Republic of
Number of Locations: 4
Lower elevation limit (metres): 1500
Upper elevation limit (metres): 1900

Population [top]

Population: The species is locally common; repeated surveys in its known areas have always recorded a small number of individuals (S. Loader pers. comm. June 2012). Its population is considered to be severely fragmented (S. Loader pers. comm. June 2012).
Current Population Trend: Unknown
Additional data:
Population severely fragmented: Yes

Habitat and Ecology [top]

Habitat and Ecology: All records are from leaf litter in montane forest. It probably cannot tolerate forest clearance. It presumably breeds by direct development, like other members of its genus, without any dependence on water.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The forest blocks where the species occurs are protected but relatively limited; it is very probably adversely affected by ongoing forest loss, especially due to subsistence small-scale agriculture, and pole cutting and logging (S. Loader pers. comm. June 2012).

Conservation Actions [top]

Conservation Actions: It occurs in Mkingu, a proposed Nature Reserve (Nguru), in addition to several other forest reserves across its distribution (S. Loader pers. comm. June 2012). These reserves are relatively well protected in comparison to other protected areas in the region, but there is still a need for increased protection and improved management (S. Loader pers. comm. June 2012). More information is needed on this species' distribution, population status and natural history, as well as clarification of its taxonomic identity.
