|Taxonomic Notes:||This species is probably a complex of at least five cryptic species (M. Vences and F. Andreone pers. comm.). Mantidactylus tricinctus was removed from the synonymy of this species by Glaw and Vences (1999).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Vallan, D. & Glaw, F.|
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This is a widely distributed species in northern and eastern Madagascar, with one record in central Madagascar. Two isolated records from west central and south-central Madagascar need to be confirmed. It occurs between 0-1,600 m asl. The map for this species is provisional as this is an unresolved species complex (F. Glaw pers. comm. May 2016).|

|Population:||It is a locally 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 streamside species in rainforest, including degraded forest and open areas adjacent to forest. It is often associated with wetlands, bogs, stagnant water and seeps, but not fast-flowing streams. It breeds in permanent and temporary pools and in slow-moving water. Knoll et al. (2007) collected one of the benthic larvae "from a puddle beside a footpath on muddy ground".|
|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 numerous protected areas throughout the eastern rainforest belt.
The taxonomy of this species complex is in need of revision (F. Glaw pers. comm. May 2016). Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
