From the IUCN Red List Species Account:

 

Range Description

This species is endemic to Montagne des Français at 260 m asl in northern Madagascar (Köhler et al. 2010). Its extent of occurrence (EOO) is 65 km2.

Habitat and Ecology

The species range is characterized by tsingy formations with wooded areas. Adults were recorded deep inside a cave on top of karstic outcrop and during the day individuals were seen next to small, shallow filled puddles. The species appears to be restricted to these karstic formations as they have not been found in any other surrounding habitat (Köhler et al. 2010).

Population

This species is known from only a few specimens from a single cave.

Population Trend

unknown

Major Threats

Because the species is restricted to caves and cracks in the karst formations, ongoing deforestation and fires lit to manage pasture do not present a major threat. However, the effects of habitat loss and degradation on the ecosytem could impact the species.

Conservation Actions

Conservation Action
This species occurs in the Montagne des Français new protected area.

Conservation Needed

It may be relatively sheltered from ongoing threats, but deforestation of surrounding areas may have unintentional ecosystem effects which may impact this species and should be monitored. Improved protection and management of the protected area is therefore required in order to halt deforestation and illegal activities in this forest, and safeguard the species.

This species has been assessed through Amphibian Ark as being in need of
Rescue, In Situ Conservation, In Situ Research, Ex Situ Research, Conservation Education, and Biobanking conservation effort (www.conservationneeds.org).

Research Needed
Further research into the population size and trends, life history and threats is required. 

Red List Status

Vulnerable (VU)

Rationale

This species is listed as Vulnerable because it is highly restricted (single threat-defined location; EOO and AOO of 65 km2) and the threats of deforestation and pasture management are not currently thought to impact the species, but could in future rapidly drive it to Critically Endangered or Extinct in a short amount of time.
