This species is known historically from northern Myanmar and China (Zhao and Adler, 1993). It is also known from northern Viet Nam and central Lao People's Democratic Republic. The type locality 'Singapore' is clearly based on a traded specimen (Bourret, 1941). It is known from altitudes up to 900m asl.
Habitat and Ecology
It inhabits forests and riparian forests in hilly areas. It breeds in still waters such as paddy fields, pools, ditches, marshes and ponds. It is mostly restricted to primary forest. The call of this species is exceptionally loud.
It is a rarely encountered species that is uncommon when encountered.
Its known areas of occurrence in Viet Nam continue to suffer from persistent processes degrading the forest, such as non-timber forest products collection, plantations, wildfires and changes to hydrology (BirdLife International 2001). Small numbers are also exported for the international pet trade.
Its range includes many protected areas. The rating of ‘Threatened’ for R. nigropalmatus in the 1992 Viet Nam Red Data Book (Tran et al., 1992) might refer in part to R. dennysii.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was included in Rhacophorus by Inger (1966), then placed in Polypedates by Liem (1970), and then returned to Rhacophorus by Dubois (1987).
