[[5][6] It is known from scattered localities across Taiwan at low to mid altitudes.[1]]Description
Adult males in the type series measure {{convert|47|-|53|mm|in|1|abbr=on}} in snout–vent length.[2] In a population in Taitung County, adult males measured {{convert|51|-|63|mm|in|1|abbr=on}} and adult females {{convert|63|-|71|mm|in|1|abbr=on}} in snout–vent length; mean male and female body mass were 8 and 15 grams, respectively.[9] The snout is short and roundish. The tympanum is nearly circular; supratympanic fold is present. The fingers and the toes are webbed and bear discs, the former larger than the latter. Skin is smooth. The dorsum is dark green; pale yellowish spots may be present. The lips are white. The venter is orange-red. The iris is plain yellow; the pupil is vertical.[2]
The male advertisement call sounds like a low-pitched "gree", lasting about 0.4 seconds.[2]
Habitat and ecology
Rhacophorus aurantiventris occurs in primary broad-leaf forests at low and mid altitudes. Breeding takes place in tree holes and buckets.[1]Cconservation
Rhacophorus aurantiventris is a rare species. It is believed to be on decline, but reasons for this are not known—its habitat is not considered threatened. It is present in Fushan Nature Reserve and Lichia Wildlife Refuge. It is classified as "endangered" in the IUCN Red List of Threatened Species[1] and in the Taiwan Wildlife Conservation Act.[5]References
