|Taxonomic Notes:||This species was removed from the synonymy of Gephyromantis decaryi by Glaw and Vences (2000).|
|Red List Category & Criteria:||Near Threatened ver 3.1|

|Facilitator/Compiler(s):||Luedtke, J. & Hobin, L.|
Listed as Near Threatened because its extent of occurrence is 24,088 km2, and the extent and quality of its habitat are declining, thus making the species close to qualifying for Vulnerable.
|Previously published Red List assessments:|
|Range Description:||This species occurs in the Ranomafana area, south through the Andringitra Mountains to the Chaines Anosyennes, in southeastern Madagascar. It has been recorded at 800-1,500m asl and possibly also occurs lower than this. Its extent of occurrence (EOO) is 24,088 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a locally abundant species. However due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits rainforest leaflitter and is not tied to water. It also occurs in secondary fern vegetation. Breeding presumably takes place by direct development.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, the invasive spread of eucalyptus, livestock grazing and expanding human settlements.
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).
It occurs in Ranomafana National Park, Andringitra National Park, and Midongy du Sud National Park.
Improved protection and management of forests throughout the region is required, including within the boundaries of protected areas.
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).
