This species is known from northeast Madagascar, where four subpopulations have been recorded between Toamasina and Tanaramé, including Anamalazoatra/Mantadia National Park (Vences et al. 2010). The species has a known extent of occurrence of 745 km2, but the precise limits of its range are poorly-assessed (Vences et al. 2010). It is currently known from sites between 770 and 1,000 m asl (M. Vences pers. comm. December 2010).
Habitat and Ecology
This is an arboreal frog of mid-elevation rainforest, which has been recorded from around 935 m above sea level. It is thought to breed by larval development in small water bodies. Calling males have been found in water-filled tree holes, which may represent reproductive habitat as they do for A. boulengerii (Vences et al. 2010).
No population status information is currently available for this species (M. Vences pers. comm. December 2010).
There is no information on major threats to this species. Its ability to tolerate habitat modification is poorly understood (Vences et al. 2010). This frog is known from too few records to establish whether agricultural encroachment into Anamalazoatra or ongoing rural development represent threats to this species (M. Vences pers. comm. December 2010).
The frog is known from at least one national protected area, Anamalazoatra/Mantadia National Park, in which it has been recorded from sites separated by ca 5 km (M. Vences pers. comm. December 2010). It has also been reported from the Mitsinjo private reserve near Andasibe Village (M. Vences pers. comm. December 2010). No species-specific conservation measures are known to be in place for this species. More information is needed on this species' distribution, population status, natural history and threats.
Red List Status
Data Deficient (DD)
Listed as Data Deficient as it has only recently been recognized as a distinct species, and more research is needed into its extent of occurrence, area of occupancy and tolerance of threatening processes.
Originally described as Mantella pollicaris by Boettger (1913), and later synonymised with A. boulengerii (Noble & Parker 1926). Removed from this synonymy by Vences et al. (2010) on the basis of molecular and acoustic data.
