About Philautus aurantium Inger, 1989
Philautus aurantium are relatively small frogs that reach a maximum snout–vent length of 30 mm (1.2 in). Their bodies are sand-colored, with black spots scattered along the flanks, the posterior section of the dorsum, and the legs. This species has pale orange coloring on the groin and the ventral side of the thighs, and its tympanum is indistinct. The natural habitats of Philautus aurantium are primary montane and submontane forests located 750–1,000 m (2,460–3,280 ft) above sea level. Males of the species call from shrubs and small trees positioned 2–4 meters above the ground. This species is threatened by habitat loss caused by clear-cutting, and it can be found within Kinabalu National Park.
