Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the family Pelodryadidae, [2] 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. [2] There is, however, some uncertainty about the western limit of this species. [2] 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. [3] 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, [3] [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. [3] [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]

<i>Nyctimystes</i> Genus of amphibians

Nyctimystes is a genus of tree frogs in the family Pelodryadidae. They are principally Papuan species, but also inhabit islands in the Moluccas. All species in this genus have one distinct feature that separates them from other species in the family, the lower eyelid is marked with pattern of lines, veins, or dots. This feature presumably acts as camouflage when the frogs are at rest during the day.

Nyctimystes avocalis is a species of frog in the family Pelodryadidae. It is endemic to Papua New Guinea and is only known from its type locality on the east slope of Goodenough Island, one of the D'Entrecasteaux Islands. It has been given the common name loud big-eyed treefrog.

It has also been suggested that the Rossel Island population might represent a distinct species.
