|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
Listed as Endangered because its extent of occurrence (EOO) is 4,759 km2, it is severely fragmented, occurring to two threat-defined locations, and there is ongoing decline in the extent and quality of its habitat in northeastern Madagascar.
|Previously published Red List assessments:|
|Range Description:||This species occurs in northeastern Madagascar, where it has been recorded from Lohanandroranga (near Bealanana) south of Tsaratanana (Rosa et al. 2014) to Andapa Fivondronana and the Anjanaharibe-Sud Massif. It is also known from near the village of Analalava in the northeast of the Masoala Peninsula (Wolf 2014). Its elevational range is 13-1,250 m asl and its extent of occurrence (EOO) is 4,759 km2.|

|Population:||It appears to be moderately common in suitable habitat, but is severely fragmented and decreasing due to ongoing habitat loss.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is a species of transitional forest and medium altitudes, with tall trees and abundant lichens, mosses and ferns where it appears to be closely associated with screw pines (Pandanus spp.). It has been found in degraded forest, providing that screw pines are still present. On the Masoala Peninsula, it is known from a tiny fragment of littoral forest, which used to stretch all along the eastern coast of Madagascar but has all but vanished and is now restricted to fragments such as this one (Wolf 2014).|
It presumably breeds by larval development in the leaf axils of screw pines.
|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.|
The major threat is habitat loss due to subsistence agriculture, timber extraction, charcoal manufacture, livestock grazing, and expanding human settlements. It is probably particularly sensitive to the collection of screw pines, which are used for making the roofs of huts. Several decades of logging valuable tree species from the genera Dalbergia and Uapaca, and ongoing agricultural exploitation have converted and disturbed the littoral forest habitat on Masoala Pensinsula (Wolf 2014).
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 in Place
It occurs in Anjanaharibe-Sud Special Reserve. The littoral forest fragment is managed by the Malagasy NGO Projet d’Analalava (Wolf 2014).
Improved protection and management of forest habitats is required.
Population and trends, life history and ecology. Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
