|Taxonomic Notes:||This species is probably a species complex (Perl et al. 2014).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Andreone, F., Glaw, F. & Vences, M.|
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species is recorded from east-central and southeastern Madagascar, at 600-1,100 m asl. Some specimens formerly assigned to this species are now thought to belong to M. brevipalmatus.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a common species. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is a forest floor species living in rainforest, but not in secondary habitats. Its breeding is unknown, but the eggs are probably laid on land with the larvae developing in streams.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements.
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).
This species occurs in several protected areas including Befotaka-Midongy National Park (Bora et al. 2007) and Betampona Strict Nature Reserve (Rosa et al. 2012).
Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
