This species is known from low altitudes (less than 100m asl) up to 1,300m asl in central Viet Nam. There are records from Bach Ma and Ba Na National Parks in the Hai Van mountain range, and also from localities further to the west closer to the Laotian border, all in Thua Thien-Hue Province. There are also records from further south, in Mang Canh Commune, Kon Plong District, Kon Tum Province. Given the distributions of other Rhacophoridae, Ranidae, and Megophryidae species, this species might also occur at over 1,000m asl in Quang Nam, Kon Tum, and Gia Lai Provinces of southern Viet Nam, and in adjacent regions of Lao People's Democratic Republic. Its distribution remains very poorly known.
Habitat and Ecology
All of the records of this species are from primary or old secondary forest, very close to small cascading forest springs falling from steep mountain slopes. It is usually found under the leaves and branches of trees and bushes at night. Jelly-like clutches of 2-10 eggs were found on the tips of large leaves on the bank of a stream in October, with larvae at different developmental stages and some clutches already deserted by the larvae. An adult male was noted to be guarding one clutch.
There is no information.
There is no information on specific threats to this species, and it is very unlikely to be the specific target of harvesting for human consumption, since it is so small and cryptic.
It is known from two protected areas: Bach Ma and Ba Na National Parks.
