Previously published Red List assessments:

Geographic Range [top]

Range Description:This species has a very uncertain distribution because of its confused taxonomic status. The type locality "East Betsileo" is presumably in east-central Madagascar, but this is not a specific locality, so no range map can be prepared for this species. Some other specimens have also been assigned to this species (for example, those from Voloina), but it is not clear that this is correct.

Use and Trade [top]

Use and Trade: There is no use and trade information for this species.

Threats [top]

Major Threat(s): The threats to this species are unknown. However, species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd), but no negative effects have been observed within amphibian populations in Madagascar suggesting the Bd strain has a low virulence level (Bletz et al. 2015).

Conservation Actions [top]

Conservation Actions: Conservation Actions
It is not known from any protected areas.

Research Needed
Research is required on taxonomy, population and trends, ecology and threats.  Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
