This species is known from the Thai-Malay Peninsula south of Chumphon in Thailand (Smith, 1930, Taylor, 1962, Dring, 1979, Kiew, 1987 and Manthey and Steiof, 1998), and is also present in Singapore (Leong, 2000). There is a single record from Buen Luoy, in southern Viet Nam (Inger et al., 1999). It is also found in Sumatra, Indonesia and has been reported from a few localities in Borneo (Malaysia and Indonesia), but these are scattered over a large portion of the island. It has an altitudinal range of 150-1,600m asl.
Habitat and Ecology
All known records originate from primary rainforest, mostly in close vicinity to flowing forest streams. Males have been seen calling from trees overhanging streams, and the larvae are presumed to live in these streams.
This is generally an uncommon to rare species in areas where it is known to occur, also indicated by the scarcity of museum series of more than a single specimen (Dring, 1979, Manthey and Steiof, 1998, Inger et al., 1999).
Deforestation of moist tropical forest is the only substantial threat to this species.
Its range includes several protected areas. Protection of tropical moist forest is the main conservation measure required for this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Past records of Rhacophorus bimaculatus (Peters, 1867) from the Malay Peninsula, Sumatra and Borneo refer to R. cyanopunctatus, 'typical' bimaculatus now being restricted to the Philippines.
