Major Threats

Conservation Actions

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.

Taxonomic Notes

Specimens recorded from Ponmudi Hills (and possibly Wayanad) as Philautus signatus are in the process of being described as the new species Philautus sp. nov. 'Ponmudi_3' (S.D. Biju pers. comm.).
