Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii) ver 3.1
Year Published: 2015
Date Assessed: 2013-08-01
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.
Contributor(s): Channing, A., Menegon, M. & Loader, S.
Facilitator/Compiler(s): Morris, E.J.
Listed as Critically Endangered as the forest area is undergoing decline in quality, and the moist valleys at the forest edge are experiencing agricultural encroachment. However, there is still very little known about this species and this should be urgently rectified.
Previously published Red List assessments:
2004 Critically Endangered (CR)

Geographic Range [top]

Range Description: This species is known only from a single forest fragment in the Ukaguru Mountains in eastern Tanzania where the only specimens were collected at 1,840 m asl. It has not been found in other, better-surveyed parts of the Eastern Arc mountain chain, so the extent of occurrence (EOO) has been estimated as 95 km2.
Countries occurrence:
Tanzania, United Republic of
Number of Locations: 1
Lower elevation limit (metres): 1800
Upper elevation limit (metres): 1850

Population [top]

Population: Only four specimens are known and a targeted search in 2007 did not find any specimens (M. Menegon pers. comm. June 2012), but due to ongoing habitat loss its population is suspected to be decreasing.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: The only specimens were collected in moist valleys but are absent from the adjoining drier montane forest (M. Menegon pers. comm. June 2012). It is arboreal. Its breeding is unknown, but the presence of large numbers of pigmented eggs in the only known specimens suggests that it is neither a live-bearer, nor a direct developer. However Channing et al. (2012) suggested that this species may have direct development.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes

Use and Trade [top]

Use and Trade: There is no information on the use or trade of this species.

Threats [top]

Major Threat(s): The forests in the Ukaguru Mountains are poorly protected; they are threatened by agricultural encroachment and human settlement.

Conservation Actions [top]

Conservation Actions: This species occurs in the Mamiwa-Kisara Forest Reserve. Urgent survey work is required to determine the biology and population status and trends of this species and the limits of its range.
