Listed as Endangered because its extent of occurrence (EOO) is 2,050 km2, it occurs in fewer than five threat-defined locations, and there is ongoing decline in the extent and quality of habitat.
|Previously published Red List assessments:|
|Range Description:||This species was previously known from only three specimens collected in 1949 at 2,600 m asl on the Tsaratanana massif in northern Madagascar, close to the summit, Maromokotro, which is at 2,876 m asl. This species has been confirmed from two further localities: Bemanevika (Bemanevika New Protected Area) and Andrevorevo (COMATSA proposed protected area), between 1,100-2,600 m asl (Rakotoarison et al. 2012). Its distribution seems to be patchy, as it was not recorded in a 2015/16 survey on a forest between Tsaratanana and Bemanevika (Ampotsidy, near Beandrarezona; Scherz et al. unpubl. data), but it is probably restricted to altitudes above 1,100 m asl (M.D. Scherz pers.comm. April 2016). The extent of occurrence (EOO) of its current known range is 2,050 km2.|

|Population:||This species is found in high densities in bamboo forest with relatively large plants (Rakotoarison et al. 2012). 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 tall montane rainforest and bamboo, and is probably not found outside mature forest. It is found almost exclusively found on bamboo, and may benefit from the presence of the nocturnal lemur Daubentonia madagascariensis for the creation of holes in the bamboo (Rakotoarison et al. 2012). It breeds in bamboo stems by larval development (Rakotoarison et al. 2012).|
|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, spread of invasive eucalyptus, livestock grazing, and expanding human settlements. It is potentially susceptible to dry season fires and, as it is a mountain-top species, it might also be at risk from global warming.
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 Bemanevika New Protected Area, Tsaratanana Strict Nature Reserve, and COMATSA proposed protected area.
Habitat protection is required for the Marojejy-Tsaratanana Corridor.
Research on population and trends, life history and ecology, and threats is required for this species. Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
