This species is known at present only from Pasoh Forest Reserve, Gombak Forest Reserve, Frim, and Templer's Park in Selangor and Negeri Sembilan States in Peninsular Malaysia. All records are from below 300m asl.
Habitat and Ecology
All records are from undisturbed lowland rainforest and associated bamboo stands (Kiew 1984a; Manthey and Grossmann 1997). Reproduction sites include water-filled bamboo stumps and other cavities.
It is quite common within its restricted range.
This species has a limited range, in which its available habitat is small, fragmented, and being converted to non-timber plantations and through infrastructure development.
Although present in several forest reserves, and Templer's Park, these areas are in need of stronger legal protection and management.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Peninsular Malaysia.
Further work might show that some peninsular populations attributed to Kalophrynus pleurostigma are referable to K. palmatissimus.
