This species is a microendemic that occurs in Tsaratanana Massif in northern Madagascar, at around 2,021 m asl (Scherz et al. 2015). Its extent of occurrence (EOO) is 1,236 km2, although this is thought to be an overestimation of its range and further studies may restrict its distribution (M.D. Scherz pers. comm. November 2015).
Habitat and Ecology
This species occurs in primary rainforest, where individuals were found under rocks and logs in a dried up spring (Scherz et al. 2015). It presumably breeds by larval development and has non-feeding tadpoles, similar to other species in the genus.
This species is known from 8 specimens. Due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.
This species is under threat from deforestation caused by agriculture activities and logging, particularly around the edges of the forest. The boundaries of Tsaratanana Strict Nature Reserve are ambiguous which makes the management of this area difficult.
This species occurs in the Tsaratanana Strict Nature Reserve.
Improved management of the reserve and the formal protection of the corridor between Tsaratanana and Marojejy is required.
Research is required on the distribution and ecology of this species.
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is 1,236 km2, it is only known from one threat-defined location and there is ongoing decline in the extent and quality of habitat.
