Litoria angiana (Boulenger 1915)

Males usually are about 50-55 mm in length, but may grow up to 65 mm. Females grow up to about 80 mm. Its large size usually distinguishes it from other species living near it. Varies highly in color: plain, pale, brown or bright leaf-green on the dorsal side with a dark line or band of yellow and brown blotches that distinctly cut off the dorsal color. Sometimes has a dark hour-glass mark on back and usually conspicuous white ridges running down the posterior sides of limbs. Sometimes very dark, nearly black, on the dorsal side without any markings, or has green or golden dorsal side with black reticulation. All have a whitish ventral surface with a varied amount of brown blotches and a fair amount of webbing between third and fourth fingers (Menzies 1975).

Ranges along central mountainous spine of New Guinea from Vogelkop Peninsula to Garaina (Zweifel 1980). Prefers vegetation along small rivers; sometimes in forests away from the water where it can be found alongside L. arfakiana (Menzies 1975).

Call: Quiet, short, rather slow, trill lasts about half a second; frequency is limited to a narrow band, giving a somewhat musical, ringing sound. Males call while usually perched in vegetation alongside rivers and creeks, and can usually be heard above the sound of running water (Menzies 1975). Reproduction: Eggs are large and unpigmented. Tadpoles are typical of frogs that are adapted to breed in similar places; the only difference is in size (Menzies 1975).

The Angiana tree frog (Litoria angiana) is a species of frog in the subfamily Pelodryadinae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist montane forests and rivers.
