The species is known from eight distantly separated localities (Anzahamaru, Betampona, Ifanadiana, Manombo, Marojejy, Ranomafana village, Tampolo, and Tolagnaro) along the east coast of Madagascar between 0-481 m asl (Köhler et al. 2015).
Habitat and Ecology
Similar to Aglyptodactylus chorus, this species occurs in lowland rainforest and individuals are occasionally found in the leaf-litter (Köhler et al. 2015). This is a relatively adaptable species that uses swamps at the forest edge and rice paddies for breeding. The species has been recorded in agricultural areas around villages (F. Glaw pers. comm. November 2015).
This species has an abundant and widespread population. However due to continuing decline in the extent and quality of the habitat, the population is suspected to be decreasing.
Forests within its range are subject to ongoing deforestation, for timber and charcoal production and to make way for rice paddies. In addition, there is regular burning to maintain cattle pasture. However, while it probably depends on the presence of forest habitat, current rates of forest loss may not have a huge impact on the species thanks to its resilience and adaptability to disturbance.
It is found in Manombo Special Reserve, Betampona Strict Nature Reserve, Marojejy National Park, is likely to be found in Ranomafana National Park.
Due to the species adaptability, no specific conservation actions are needed. However, improved protection of remaining forest in this region is required.
Further work is needed to clarify the taxonomy of the species, the limits of its range and its ecological requirements.
Red List Status
Least Concern (LC)
Listed as Least Concern because of its wide distribution, relative adaptability to disturbance, and presumed large population.
This species has been removed from synonymy of Aglyptodactylus madagascariensis (Köhler et al. 2015). A record from Marojejy (Köhler et al. 2015) currently assigned to A. inguinalis is included in this concept, but is expected to be assigned to A. chorus following further study. It is possible this species could be a taxonomic complex with different lineages at Marojejy, Tampolo/Betampona and in the southeast, although further research is required and confirmation of the identity the sub-population in Anzahamaru (type locality) is needed through new collections (Köhler et al. 2015).
