The Silent Valley Tropical Frog was previously known only from the two individuals in the original description found in Silent Valley National Park, Kerala in 1980.

An unusual discovery:  This find was the outcome of the first LAI expedition after the Delhi launch on 4 November 2010. The Silent Valley Tropical Frog was unexpectedly located in a rubbish bin near the Silent Valley trek path.  After being lost to science for 30 years, it was rediscovered by Don Church, Robin Moore, Franky Bossuyt, Ines Van Bocxlaer, Gower David, Mark Wilkinson, Darrel Frost,
Wes Sechrest and SD Biju.

The team further observed several more individuals adjacent to a streambed under leaf litter in closed forest cover within the Kunthi river watershed. More field studies are essential to ascertain the biology and conservation status of this species.

Listed on the IUCN Red List of Threatened Species as Data Deficient (DD).
