Nyctimystes avocalis is a species of frog in the family Pelodryadidae. [3] 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. [3] It has been given the common name loud big-eyed treefrog. [1] [3]

Description

The type series consists of three males and two females. The males measure 33–35 mm (1.3–1.4 in) and the larger female 47 mm (1.9 in) in snout–vent length. The canthus rostralis is distinct as is the tympanum, although the upper margin of the latter is concealed by the supratympanic fold. The outer fingers are half-webbed. The hind limbs are relatively long and the toes are almost fully webbed. Skin is dorsally mildly granular and ventrally (including the throat) coarsely granular. The dorsal ground color is usually gray and there are lichen-like patches of tan on the body and the back of the head. One specimen, however, is brown without obvious markings. The tibia are irregularly banded. Males lack vocal sac and vocal-sac openings, which is unusual within the genus Nyctimystes. [2]

Habitat and conservation

The type series was collected near a small creek in oak-rain-forest transition at about 900 m (3,000 ft) above sea level. [2] Breeding probably occurs in torrential streams where the tadpoles develop. [1]

The lower altitudes of Goodenough Island (below 300 m (980 ft)) are heavily impacted by gardening and fires, as well as expanding human population, but as of 2004, higher altitudes were intact. Nyctimystes avocalis is not known from any protected areas. [1]

<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 daymani, also known as the Dayman big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and known from its type locality, Mount Dayman in the Milne Bay Province, easternmost mainland New Guinea. Records from further west are uncertain.

Nyctimystes fluviatilis, also known as the Indonesian big-eyed tree frog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to New Guinea and is known from Idenburg River and Wapoga River in Papua province, Indonesia, and from the Torricelli Mountains in the East Sepik Province and Kavorabip in the Western Province, both in the western Papua New Guinea.

Nyctimystes kubori is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and is widespread in the New Guinea Highlands between 141°E and 147°E and in the mountains of the Huon Peninsula. The specific name kubori refers to its type locality in the Kubor Mountains. Common name sandy big-eyed treefrog has been coined for this species.

Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the family Pelodryadidae, or alternatively, subfamily Pelodryadinae in the family Hylidae. 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. There is, however, some uncertainty about the western limit of this species. Despite its vernacular name, Nyctimystes narinosus is not a common species.

Nyctimystes perimetri, also known as the archipelago big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and currently only known from the Louisiade Archipelago, although it might also occur in the Owen Stanley Range of the mainland Papua New Guinea. It has also been suggested that the Rossel Island population might represent a distinct species.

Nyctimystes persimilis, also known as the Milne big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and known from Mount Dayman and Mount Simpson in the Owen Stanley Range.

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 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 tyleri 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 only known from its type locality, Gapaia Creek, between Garaina and Saureli, in the Morobe Province. The specific name honours Michael J. Tyler, an Australian herpetologist, "in recognition of his notable contributions to the systematics of Australo-papuan frogs." Common name Tyler's big-eyed treefrog has been coined for this species.

Aphantophryne sabini is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the region of its type locality, Myola Guest House in the Owen Stanley Range, Northern Province. The specific name sabini honors Andrew E. Sabin, an American businessman, philanthropist, and environmentalist who joined the expedition during which the holotype of this species was collected. However, its vernacular name Guest House Guinea frog refers to the type locality instead.

<i>Papurana waliesa</i> Species of amphibian

Papurana waliesa is a species of "true frogs", family Ranidae. It is endemic to Papua New Guinea where it is found in the southern Owen Stanley Range and the Pini Range in the eastern New Guinea as well as in the D'Entrecasteaux Islands.
