|Taxonomic Notes:||This species was redefined, and two new species, Mantidactylus charlotteae and M. zipperi, were described by Vences and Glaw (2004).|
|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Glaw, F. & Vences, M.|
Listed as Endangered because its extent of occurrence (EOO) is 1,851 km2, there is ongoing decline in the extent and quality of the habitat and it occurs in less than five threat-defined locations.
|Previously published Red List assessments:|
|Range Description:||This species is known only from two localities of Andasibe and An'Ala, between 850–900 m asl. Its EOO is 1,851 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is locally abundant. 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:||This terrestrial species is often found near streams, usually in pristine or only slightly disturbed rainforest. It breeds in streams and the eggs are presumably laid on land.|
|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, 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 Analamazaotra Special Reserve.
Habitat protection is required to ensure the survival of the species.
Further research on the distribution and taxonomy of the Chonomantis subgenus is necessary to clarify the distribution of this species. It is likely to occur outside the currently known area, and may in future be down-listed into a lesser threat category. Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
