This species is known only from the type locality of "near Valiaparai Thodu, Silent Valley Forests, Kerala" (Pillai 1981) in the Western Ghats of southern India. The type specimen was collected at an altitude of 800m asl.
Habitat and Ecology
This is a terrestrial species described from relatively open tropical moist forest. It may occur under rocks close to hill streams, but there is no further information known about its habitat and ecology.
It is known only from the holotype, as it has not been found again despite surveys within its range, so its population status is unknown.
The threats to this species are not known.
It is unclear as to whether or not the type specimen was collected within Silent Valley National Park.
This taxon is probably a junior synonym of Bufo parientalis (Dubois and Ohler 1999; Biju in prep.). It is thought that the type specimen of B. silentvalleyensis might refer to a subadult of B. parietalis, and that this taxon is therefore invalid.
