Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the subfamily Pelodryadinae of the family Hylidae. [3] [4] It is endemic to New Guinea and occurs in the Wahgi-Sepik Dividing Range and the Schrader Mountains, on both sides of the border between Papua (Indonesia) and Papua New Guinea. [3] There is, however, some uncertainty about the western limit of this species. [3] Despite its vernacular name, Nyctimystes narinosus is not a common species. [1]
The holotype, an adult female, measures 64 mm (2.5 in) in snout–vent length. [2] Males measure 48–59 mm (1.9–2.3 in) in snout–urostyle length. [5] The snout is high and blunt. The canthus rostralis is distinct. The tympanum is small but distinct, [2] [5] partly obscured by the prominent supratympanic fold. The palpebral reticulum forms an irregular broken network of brown lines. [5] The fingers hava basal webbing whereas the toes are about three-quarters webbed. [2] [5] The dorsum is usually chocolate brown, sometimes paler. There is a varying amount of cream to bright orange decoration consisting of scattered blotches and broad dorsolateral bands that reach the lores; this color may occasionally cover the entire dorsum. The brown coloration fades on the flanks to an off-white belly with brown speckling, with denser speckling on the throat. The lips are spotted, The iris is mid-brown. Males have a subgular vocal sac. [5]
The male advertisement call is a very loud "whistle". The tadpole is large and black or dark. [5]
Ecology of Nyctimystes narinosus is poorly known. [1] [5] It is a high-altitude species, being found at elevations of 1,500–2,500 m (4,900–8,200 ft) above sea level [1] or higher. [5] In the Schrader Mountains, it only occurs in Nothofagus forest, living high in the trees. [5] If similar to other Nyctimystes, the eggs are laid in torrential streams. [1]
Nyctimystes narinosus is a low-density species. It is not known to occur in any protected areas. [1] It is consumed locally. [5]
