From the IUCN Red List Species Account:

 

Range Description

This species occurs in the Sorata Massif in northern Madagascar around 1,580 m asl (Scherz et al. 2015). The full extent of its distribution is currently unknown and surveys needs to be carried out to get a better understanding. It occurs in one threat-defined location and its extent of occurrence (EOO) is 672 km2 .


Habitat and Ecology

This species is found in primary, montane forest at high altitudes (Scherz et al. 2015). Due to its distinctive appearance (long legs), it is thought that it is unlikely to have been misidentified in other areas of Madagascar and so it could be microendemic to a small area in and around Sorata (Scherz et al. 2015). As a member of Cophylinae, it is likely to lay eggs away from water and have endotrophic tadpoles (Scherz et al. 2015).

Population

It is only known from two specimens (an adult female and an adult male) (Scherz et al. 2015). As this species has not been found on previous expeditions, it could be suggested that it is scarce, seasonal or has a scattered distribution (Scherz et al. 2015). Despite the limited amount of data, ongoing declines in the extent and quality of habitat suggest that the population might be decreasing.

Population Trend

decreasing

Major Threats

All locally endemic species in Sorata are threatened by deforestation and habitat degradation (Scherz et al. 2015), caused by logging and agricultural activities, which is particularly severe towards the forest edges (M.D. Scherz pers. comm. November 2015).

Conservation Actions

Conservation Actions
This species does not occur in any protected areas.

Conservation Needed
All forests in Sorata are unprotected (Scherz et al. 2015), thus habitat protection is urgent.

Research Needed
Research is required to determine the full distribution of this species, its ecology and life history.

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its extent of occurrence (EOO) is 672 km2, it is only known from one threat-defined location and there are ongoing decline in the extent and quality of habitat.
