Morobe big-eyed treefrog
Nyctimystes trachydermis, also known as the Morobe big-eyed treefrog, is a species of frog in the family Pelodryadidae, or alternatively, subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and occurs in the mountains of southern eastern New Guinea. Its type locality (which it shares with Nyctimystes tyleri ) is Gapaia Creek, at 1,280 m (4,200 ft) asl between Garaina and Saureli, in the Morobe Province. The specific name trachydermis means "rough skinned", derived from the Greek words trachys and derma.
Nyctimystes trachydermis are relative large frogs, with adult males measuring 72–88 mm (2.8–3.5 in) in snout–vent length. One gravid female measured 76 mm (3.0 in). Dorsal surfaces are roughed throughout with small, mostly conical and white-tipped asperities. Dorsal ground colour varies from dark greenish brown to gray. Some specimens have lighter blotches. Iris is reddish brown with distinct vertical pupil. Tympanum is completely concealed. Vocal sac is absent.
