Nyctimystes narinosus

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

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]

gollark: As a Go developer, you have surely encountered at some point something using the `container` package, containing things like `container/ring` (ring buffers), `container/list` (doubly linked list), and `container/heap` (heaps, somehow). You may also have noticed that use of these APIs requires `interface{}`uous type casting. As a Go developer you almost certainly do not care about the boilerplate, but know that this makes your code mildly slower, which you ARE to care about.
gollark: High demand for generics by programmers around the world is clear, due to the development of languages like Rust, which has highly generic generics, and is supported by Mozilla, a company. As people desire generics, the market *is* to provide them.
gollark: Hmm.
gollark: Interesting!
gollark: In languages such as Haskell, generics are extremely natural. `data Beeoid a b = Beeoid a | Metabeeoid (Beeoid b a) a | Hyperbeeoid a b a b` trivially defines a simple generic data type. It is only in the uncoolest of languages that this simplicity has been stripped away, with generic support artificially limited to a small subset of types, generally just arrays and similar structures. Thus, reject no generics, return to generalized, simple and good generics.
