|Taxonomic Notes:||This species was elevated from subspecific to specific status by Vences, Glaw and Böhme (1999). Genetically, it is extremely closely related to Mantella baroni (Perl et al. 2014).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Raxworthy, C.J., Andreone, F. & Glaw, F.|
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species occurs in northern and northeastern Madagascar from Tsaratanana south to Zahamena, at 100-1,240 m asl (Rakotomalala et al. 2001). It has also recently been confirmed from Betampona (Rosa et al. 2012).|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a locally abundant 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 lives on the ground along streams in rainforest and forest edge, but not in severely degraded habitats. It presumably breeds like other species in the genus, with the eggs laid on land and larvae developing in streams.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||This species is found in the international pet trade but in low numbers.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements. It has so far only been traded internationally in very small numbers, but there could be greater demand in the future.
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 Betampona Strict Nature Reserve) and is listed on CITES Appendix II.
Any future trade in this species should be carefully regulated.
Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
