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.
Deforestation driven by agricultural and human settlement expansion is prevalent within its range and is likely to be putting pressure on the species.
This species is found in the region of Ampombofofo, which has no formal protection.
Protection of forest habitat is needed in the face of ongoing deforestation.
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.
