Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2017
Date Assessed: 2017-01-03
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Luedtke, J.
Contributor(s): Andreone, F., Glaw, F., Scherz, M.D. & Vences, M.

Listed as Endangered because the species is currently only known from the Andringitra Massif with an extent of occurrence (EOO) of 1,313 km2, which represents fewer than five threat-defined locations, and there is ongoing habitat loss outside the Andringitra National Park.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species has been reliably identified only from the Andringitra Massif, between 1,400–2,000 m Asl. Further research might show it to occur more widely, but the EOO of its current known range is 1,313 km2.

Population [top]

Population:There is no information on its abundance and the population trend is unknown.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species requires clean streams, usually in forest, and above the tree line in montane grassland. It probably does not occur in degraded habitats. It breeds in streams 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 records of this species being utilized.

Threats [top]

Major Threat(s): All currently known records are within a protected area, but if it occurs more widely, its habitat is probably being impacted by overgrazing and fires (which are likely to be too frequent).

Species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd), however currently there have been no negative effects observed within amphibian populations in Madagascar suggesting the Bd strain has a low virulence level (Bletz et al. 2015). High-altitude species are known to be more vulnerable to Bd, so this species is more likely than some others to be at risk on Madagascar (F. Glaw pers. comm. May 2016).

Conservation Actions: Conservation Actions
This species occurs in the Andringitra National Park.

Research Needed
Research is needed to determine its geographic range and ecological requirements. Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
