Species Description: Menzies JI Richards SJ Tyler MJ 2008 Systematics of the Australo-Papuan tree frogs known as Litoria bicolor (Anura: Hylidae) in the Papuan region. Australian Journal of Zoology 56:257-280.
Description: Adult males reach a maximum of 23.5 mm HB. Adult females measure up to 26.4 mm HB. Granular dorsal skin with coarse ventral skin, except for smooth throat. Head is longer in length than width. Large eyes. Pupils horizontal. Snout is obtusely pointed in dorsal view, and rounded in profile. Rounded and straight canthus rostralis. Tympanum small. Supratympanic skin fold obscures upper margin of tympanum. Fingers usually unwebbed; sometimes basal webbing to 1/3 webbing between Fingers III-IV. Finger discs larger than toe discs. Legs are long. Toes are almost completely webbed except for terminal phalanges which are usually free on Toes I, II and IV (occasionally, toe webbing may be complete, except for Toe IV). Males have a brown nuptial pad on the medial surface of Finger I (Menzies et al. 2008).
In life, green dorsum with a mid-dorsal bronze stripe. Narrow and dark canthal stripe that runs from the eye to the tympanum, then becomes indistinct, separating the green dorsum from the white ventrum. White upper lip with the white coloring extending below the eye and tympanum and eventually merging into the white venter. Dark brown groin and concealed surfaces of the thigh. Males have pale yellow throats (Menzies 2008).
