This species is known only from the type locality and one close by in Montagne d’Ambre National Park, Diana Region, northern Madagascar, between 900-1,050 m asl. It seems to be a local endemic since, despite rather intensive surveys in other areas of northern Madagascar, it has not yet been found elsewhere (Rakotoarison et al. 2015). Its extent of occurrence (EOO) is 299 km2.
Habitat and Ecology
This is a terrestrial, forest species. It has been found during the day and night in a bamboo patch near the entrance office of Montagne d’Ambre National Park. No further information is available on the natural history and reproduction of this species. It presumably breeds by larval development inside of holes in bamboo.
Due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.
Montagne d'Ambre is subject to limited anthropogenic pressure, especially at its edges, so the species is threatened by habitat loss from agricultural activities and logging (Rakotoarison et al. 2015). Fire is also a potential threat to its habitat (M. Scherz pers. comm. November 2015).
It occurs in Montagne d’Ambre National Park.
Continued work to maintain the integrity of park boundaries is required.
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
Listed as Endangered because its extent of occurrence (EOO) is 299 km2, it only occurs in one threat-defined location and, despite occurring in a well protected area, there is ongoing declines in the extent and quality of habitat.
