It is endemic to the Papua Province of Indonesia, and found on Yapen Island (its type locality) as well as on the foothills of the Foja Mountains in the mainland New Guinea.

Description
Males measure 41–47 mm (1.6–1.9 in) in snout–vent length. The snout bears a conspicuous dermal spike. The Tympanum is small but prominent. Fingers are long, extensively webbed, and with large terminal discs. Dorsal colour varies and can be light blue-grey, greenish, brownish, or a mixture of greenish and brownish. There are blackish or brownish markings which, together with crenulated fringes on extremities and skin lappets on margin of lower jaw, contribute to camouflage of resting individuals.
The advertisement call typically consists of three notes, one long note with several subnotes, and two short notes, without subnotes. Dominant frequency is about 1800 Hz. Calling starts at dusk and lasts until at least midnight.
Habitat and conservation
Litoria humboldtorum inhabits primary tropical moist forest, but it can also be found in partly logged and regenerating areas of forest. They are typically found near water or road margins, perched on vegetation 2–6 m above the ground. The altitudinal range is 500 to 1,050 m (1,640 to 3,440 ft) asl.
Litoria humboldtorum is an uncommon species, but it appears to be reasonably adaptable, and no threats have been identified.
