Identification. Rhacophorus bipunctatus is a mediumsized treefrog distinguished from other Rhacophorus species by its green coloration, webbed front feet, orange toe/finger webbing without black spots, and two ink-black spots on the flanks ( Bordoloi et al. 2007). The primary call was an insect-like run of 200–700 ms with distinct 8–10 ms pulses at 16–17 pulses/s and dominant frequency of 1800–2200 Hz. It was also heard to make a Polypedates -like “quack” at times, a 110–150 ms call with a pulse rate of 40–50 pulses/s and frequency peak at 2200–2500 Hz. We follow Bordoloi et al. (2007) in considering R. htunwini to be a junior synonym of R. bipunctatus .

Taxonomic notes. Rhacophorus bipunctatus is morphologically similar to R. rhodopus Liu & Hu, 1960 , and more work is necessary to sufficiently describe and sepa- rate these species, but currently there is no evidence that R. rhodopus is found in south Asia (Chan Kin Onn pers. comm.).

Habitat. This treefrog was only found in mature forest, especially where large trees were most dense.
