Listed as Endangered because the extent of occurrence is 795 km2, it is known from fewer than five locations, and there is ongoing decline in the quality and extent of its habitat.
|Previously published Red List assessments:|
|Range Description:||This species is known with certainty only from the Andasibe area in eastern Madagascar. It is probably more widespread, but the limits of its range are unknown. Records from further south appear to be referable to other species. It has been recorded at 800-1,200 m asl and its extent of occurrence (EOO) is 795 km2.|

|Population:||It is locally very abundant within its known range, especially in secondary fern forest. However, due to the ongoing decline of forest habitats in eastern Madagascar, its population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It lives in primary, secondary and degraded forest and low secondary vegetation. While this indicates a degree of resilience, it is never found far from closed forest. It is most often observed on low vegetation far from water. It breeds by direct development and is not associated with water.|
|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.|
While the species is resilient to moderate decline in the quality of its habtiat, it does require the presence of undisturbed forest to survive. It is, therefore, threatened by the loss and degradation of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacture, 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 Andasibe-Mantadia National Park and Analamazaotra Special Reserve.
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).
