Description
Rhacophorus reinwardtii is a medium to large-sized tree frog with a broad head (Inger and Stuebing 2005). Females have a snout-vent length of 55.4-79.6 mm, while males range from 41.6-52.5 mm (Ohler and Delorme 2006). The dorsal skin is smooth (Ohler and Delorme 2006) or granular (Inger and Stuebing 2005). There is a wide flap of skin on the outer edge of the forearm (Inger and Stuebing 2005). It has complete webbing of the hands and feet (Ohler and Delorme 2006). The heel has a wide, rounded flap and continues as a narrow fringe along the lower leg (Inger and Stuebing 2005). Sexual dimorphism is present, but is not as distinct in females (Ohler and Delorme 2006).

The tadpole morphology is typical of its genus; a large, oval and slightly flattened body that has a total length up to 60 mm. The leaf-shaped tail is less than 2x the body length. The tadpole coloration is gray-brown with scattered black spots (Inger and Stuebing 2005).

In the adult frog, coloration of the dorsal surface is a dark green with dark spots, fading into a golden yellow on the flank. The side also has a black band with turquoise blue spots. Webbing is black with golden yellow and bright blue spots. The underside of the frog is pure white (Inger and Stuebing 2005).

This species can be found in Java (Schlegel 1837; Iskandar 1998) and Sumatra, Indonesia; Sarawak and Sabah, Borneo (Inger and Stuebing 2005), on Peninsular Malaysia (Grandison 1972; Berry 1975; Dring 1979), and in southern Thailand (Taylor 1962; Chan-ard 2003). It has not been recorded from Brunei or Kalimantan (Indonesia), but it is thought likely to occur there also (Stuart et al. 2008). It occurs mainly at low elevations in primary rainforests (Inger and Stuebing 2005), but has been recorded up to 1,400 m asl (Stuart et al. 2008).

Life History, Abundance, Activity, and Special Behaviors
This is a canopy-dwelling species, but descends to the forest floor for breeding in semipermanent pools (Inger and Stuebing 2005). It is an explosive breeder (Stuart et al. 2008). Rhacophorus reinwardtii constructs foam nests above breeding ponds in the forest (Stuart et al. 2008).

The call has been described as sounding like a low crackling chuckle (Inger and Stuebing 2005).

It is speculated that the adults most likely feed on canopy insects (Inger and Stuebing 2005).

Trends and Threats
Rhacophorus reinwardtii has a decreasing population trend (Stuart et al 2008). It is considered to be rare, but as a canopy species it is difficult to observe (Stuart et al. 2008). However, it is suggested that it might be locally abundant because of adults that are observed to congregate in the dozens at pools for breeding (Ohler et al. 2006). Reports from Borneo are rare (Inger and Stuebing 2005).

It is dependent on relatively undisturbed mature lowland rainforest (Stuart et al. 2008). Significant loss of rain forest habitat due to logging, agricultural expansion and human settlements is the main threat to Rhacophorus reinwardtii (Ohler and Delorme 2006). This species is also threatened by water pollution, smaller-holder and agro-industry farming (Ohler and Delorme 2006). It apparently does not occur within any adequately protected areas (Stuart et al. 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Habitat fragmentation

Comments
The official description of the species is recorded by Frost in Amphibian Species of the World (http://research.amnh.org/vz/herpetology/amphibia/index) as Schlegel (1840), but Inger and Tan (1996) record it as Schlegel (1837).

Specimens from Viet Nam are now considered to belong to Rhacophorus kio (Ohler et al. 2006).
