This montane species has been recorded from the Banjaran Bintang mountain range of Peninsular Malaysia and the Banjaran Titi Wangsa mountain range of Thailand and Peninsular Malaysia. It might also be present in the mountain ranges of Banjaran Benom, Banjaran Gunong Tahan and Banjaran Timur, all in Peninsular Malaysia, and might also occur in the highlands of the island of Sumatra, Indonesia. It has an altitudinal range of at least 700-1,300m asl.
Habitat and Ecology
It does not occur in modified habitats, but it appears to be a strict inhabitant of undisturbed streams in highland and montane tropical forests. Adult males have been observed calling from the sides of forest streams while perched low on fallen branches or live vegetation, or on sandy banks or leaf-litter. The larvae inhabit well-shaded streams with clear, slow-flowing water and a sandy substrate.
The population status of this species is unknown.
The habitat of this species is threatened, at least locally, by logging and smallholder agricultural development.
It has been recorded in the Hala Bala Wildlife Sanctuary of Thailand, and the Cameron Highlands Wildlife Sanctuary of Peninsular Malaysia. It might also be present in other protected areas of the Banjaran Bintang and the Banjaran Titi Wangsa mountains.
Adults and larvae of this montane species have previously been misidentified as either Hylarana signata or H. glanulosa.
