This species is only found in the type locality in an abbey garden (624m asl) in Joffreville and the nearby Fontenay Private Nature Park (720 m asl), Antsiranana II District in Diana Region, northern Madagascar, between 634-720 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). However, it is possible that this species could occur in the dry forest adjacent to Forêt d'Ambre Special Reserve (M.D. Scherz pers. comm. November 2015). Its current extent of occurrence (EOO) is 55 km2.
Habitat and Ecology
This is a terrestrial, forest species. About eight calling males were heard from the same small patch of bamboo in the garden of an abbey in Joffreville, north Madagascar. During the day, at the same site, one female with oocytes and one male were found in a bamboo trunk, together with five juveniles. No further information is available on the natural history and reproduction of this species. It presumably breeds by larval development.
Due to ongoing threats in the extent and quality of habitat, the population is suspected to be decreasing.
Found in the protected area of Forêt d'Ambre Special Reserve, which despite being legally protected, is under high deforestation pressure from agriculture and logging (e.g., Glaw et al. 2012).
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).
Found in Forêt d'Ambre Special Reserve.
Increased protection of dry forest habitat is required.
Research is required on its population status and ecology. Further research is also 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 55 km2, it is only found in one threat-defined location and, despite having some protection, there is ongoing decline in the extent and quality of habitat.
