From the IUCN Red List Species Account:


Range Description

This species is known only from Montagne d’Ambre National Park, Diana Region, northern Madagascar, between 1,246-1,306 m asl.  It seems to be a local endemic since it has not yet been found elsewhere despite rather intensive surveys in other areas of northern Madagascar (Rakotoarison et al. 2015). Its extent of occurrence (EOO) is 30 km2.

Habitat and Ecology

This species is found in primary montane rainforest. The holotype was found during the day with metamorphosing tadpoles in a tree hole in highland forest. Regularly observed calling, typically from low perches of ca. 100–150 cm above ground level on leaves, but in a few cases also from higher perches of above 2 m from the ground (Rakotoarison et al. 2015). It presumably breeds by larval development inside tree holes. An ovigerous female that was found contained 21 eggs.


Due to ongoing decline in the quality and extent of its habitat, the population is suspected to be decreasing at an unknown rate.

Population Trend


Major Threats

As this species does not occur near the forest edges of Montagne d'Ambre National Park, it is probably at low risk of large-scale habitat loss from agricultural activities and logging. However the two known localities of this species show signs of recent and ongoing anthropogenic habitat modification on a smaller scale (A. Rakotoarison pers. comm. November 2015).

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

Conservation Actions
Found in Montagne d’Ambre National Park.

Conservation Needed
Continued work to maintain the integrity of park boundaries is required.

Research Needed
Further research is required on its population status 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).

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because its extent of occurrence (EOO) is 30 km2, it is only known from one threat-defined location and there are ongoing declines in the extent and quality of habitat.
