It presumably breeds by larval development.
Numerous specimens were heard in the evening in dense primary forest directly next to Camp Simpona at Marojejy National Park (Glaw et al. 2012). The population is therefore assumed to be relatively abundant. The trend of the population is unknown, but it could be decreasing if it occurs within the mapped area and where habitat loss is occurring.
Intensive illegal wood extraction of rosewood species within Marojejy National Park that followed the 2009 political crisis of Madagascar caused concerns for the survival of rainforest–restricted species, such as this one. However, while illegal rosewood logging has probably ceased, wood extraction currently taking place in the Park seems to occur at lower elevations and is not thought to have reached elevations where this species has been recorded; along the boundaries of Marojejy deforestation is taking place to clear land for agriculture (F. Glaw 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).
This species occurs in Marojejy National Park.
Improved protection of forests in the region is required.
Further research is required to clarify the species' distribution, population size and trends, and it is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
Red List Status
Listed as Endangered because the extent of occurrence is 780 km2, it is known from fewer than five threat-defined locations and there is continuing decline in the extent and quality of its habitat.
Referred to by Glaw and Vences (2007) as Platypelis sp. aff. mavomavo 2, by Wollenberg et al. (2008) and as Platypelis sp. 4 by Vieites et al. (2009).
