Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the family Pelodryadidae,[3] or alternatively, subfamily Pelodryadinae in the family Hylidae.[1][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]
Names
It is known as mabas in the Kalam language of Papua New Guinea.[5]
Description
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.[6] The snout is high and blunt. The canthus rostralis is distinct. The tympanum is small but distinct,[2][6] partly obscured by the prominent supratympanic fold. The palpebral reticulum forms an irregular broken network of brown lines.[6] The fingers hava basal webbing whereas the toes are about three-quarters webbed.[2][6] 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.[6]
The male advertisement call is a very loud "whistle". The tadpole is large and black or dark.[6]
Habitat and conservation
Ecology of Nyctimystes narinosus is poorly known.[1][6] 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.[6] In the Schrader Mountains, it only occurs in Nothofagus forest, living high in the trees.[6] 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.[6]
