Listed as Endangered because its extent of occurrence is 1,446 km2, it occurs in three threat-defined locations, and there is ongoing decline in the quality and extent of its habitat.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is known from a few sites in eastern Madagascar: Vohidrazana at 850 m asl and nearby Analambalo, and a second population tentatively referred to as this species is known from Betampona Strict Nature Reserve at 517 m asl (Rosa et al. 2012), which is included in this taxon for the purposes of this assessment. It is suspected to occur between these two sites and its extent of occurrence (EOO) is 1,446 km2.

Population [top]

Population:It is uncommon and, due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Specimens have been found in old secondary forest vegetation, calling from leaves 2 m or more above the ground. This species is presumed to breed in brooks and streams.
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): Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing and expanding human settlements. Pressure on the forest is especially high at the type locality (Ambavaniasy at a site called Analambalotra) where wood extraction activities by local villages is ongoing (F. Glaw pers. comm. November 2015). The type locality was visited in 2016 and almost no forest was left along the stream at Analambalotra outside Ambavaniasy; the species may even already be extinct at this particular site, highlighting the extreme pace of habitat destruction in the area (D. Edmonds pers. comm. March 2016).

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).

Conservation Actions [top]

Conservation Actions: Conservation Actions
Found within the region of the Betampona Strict Nature Reserve.

Conservation Needed
Further protection of forest habitats in the region is required.

Research Needed
Further research is required to clarify the species' distribution, population size and trends, and is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
