|Taxonomic Notes:||This species is closely related to Mantella madagascariensis (F. Glaw pers. comm.).|
|Red List Category & Criteria:||Near Threatened ver 3.1|

Listed as Near Threatened because it is close to qualifying for Vulnerable under the B criterion: its extent of occurrence (EOO) is 23,817 km2, it occurs in fewer than 10 threat-defined locations, and there is continuing decline in the extent and quality of its forest habitat in northeastern Madagascar.
|Previously published Red List assessments:|
|Range Description:||This species has been recorded in northeastern Madagascar from Mananara-Nord, south to An'Ala, at 300–950 m Asl. It has also been recorded in Andriakanala in Bemanevika, between 1590–1730 m Asl (Rabearivony et al. 2010), but due to the high altitude of this locality, this record is in need of confirmation and has been excluded from the range map (F. Glaw pers. comm. May 2016). Its EOO is 23,817 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a rare 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 terrestrial species of swampy rainforest, and does not occur in secondary habitats. It breeds in swamps in forest.|
|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 in low numbers (F. Glaw pers. comm. May 2016).|
Its forest habitat is receding due to subsistence agriculture (including livestock grazing), timber extraction, charcoal manufacture, the spread of invasive eucalyptus, and expanding human settlements. It is possible, but unlikely, that over-collecting for commercial and private purposes is a threat, but this requires further investigation.
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 the Reserve De Biosphere De Mananara Nord and the Réserve Spéciale d' Ambatovaky. It is listed on CITES Appendix II.
There is a need for careful regulation of the trade in this species and ongoing protection of its habitat.
The identity of the northernmost record near Bemanevika from Rabearivony et al. (2010) should be taxonomically clarified (F. Glaw pers. comm. May 2016). Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
