From the IUCN Red List Species Account:


Range Description

This species is only known from the type locality in small caves at Ampombofofo, at 20 m asl (Köhler et al. 2010), however, it is expected to occur much more widely.

Habitat and Ecology

The species has been recorded in a small cave where primary forest meets riparian habitat, with a river running nearby, and also inhabiting secondary forest. Unconfirmed records from near a rice paddy (Köhler et al. 2010) require confirmation. It is presumed to breed by larval development using foam nests, similar to other species in the genus.


Few individuals have been found during the day. Due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend


Major Threats

Deforestation driven by agricultural and human settlement expansion is prevalent within its range and is likely to be putting pressure on the species.

Conservation Actions

Conservation Action
This species is found in the region of Ampombofofo, which has no formal protection.

Conservation Needed
Protection of forest habitat is needed in the face of ongoing deforestation.

Research Needed
Further research into its distribution, population size and trends and threats is necessary.

Red List Status

Data Deficient (DD)


Listed as Data Deficient because suitable habitat is available both to the north and south of the single confirmed site, thereby creating too much uncertaintly around the limits of its range.
