Aphantophryne parkeri is a species of frog in the family Microhylidae. It is endemic to the north coast of New Guinea and only known from Matapan (or Matapau) and the Bewani Mountains in the West Sepik Province, Papua New Guinea, and from Sentani in the Papua Province, Western New Guinea (Indonesia). [2] This species was formerly included in the genus Oreophryne , but was in 2017 moved to Aphantophryne based on molecular data. [2] [3] The specific name parkeri honours Hampton Wildman Parker, an English zoologist and herpetologist. Common name Parker's cross frog has been coined for it. [4]

Description

Adult males measure about 23–24 mm (0.91–0.94 in) and adult females 26–29 mm (1.02–1.14 in) in snout–vent length (each of these ranges is based on just two specimens). The head is relatively narrow. The snout bluntly rounded, approaching truncate, in dorsal view, and vertical in profile. The canthus rostralis is rounded. The tympanum is moderately distinct to indistinct. The fingers and the toes have well-developed terminal disks. The fingers have no webbing whereas the toes have moderate webbing. The dorsum is light brown and has irregular darker small spots interrupted by a sharply defined, dark W-like mark in the scapular area. There are abundant tiny white spots over all dorsal and lateral surfaces and limbs. The iris is dark brown. [5]

The male advertisement call is a train of 21–34 notes, with a dominant frequency of 2600–2900 Hz. The notes are uttered at a rate of 5 s−1, and the call lasts about 5 seconds. [5]

Habitat and conservation

Aphantophryne parkeri occurs in very disturbed forests and sago swamps in highly disturbed habitats at 90–300 m (300–980 ft) above sea level. [1] The type series was reported as having been collected "from running water in sago-palm forest", but this is likely erroneous because no related species is aquatic; an earlier account on the same specimens stated them having been collected "near running water". In Sentani, males were calling from about 3–6 m above ground in banana plants and sago palms in an area of garden regrowth. [5]

There are no known threats to this species, and it appears to adapt to disturbance. It is common in the Papuan locality. It presumably occurs in Cyclops Nature Reserve. [1]

<i>Aphantophryne</i> Genus of amphibians

Aphantophryne is a genus of microhylid frogs found in New Guinea and in Mindanao, the Philippines. Originally described by Fry in 1917, Richard G. Zweifel considered in 1956 Aphantophryne synonymous to Cophixalus. The genus was resurrected in 1989 to house two new species in addition to the type species, A. pansa. A molecular study on the subfamily Asterophryinae in 2017 revealed that two species originally included in the genus Oreophryne were more closely related to Aphantophryne than to other Oreophryne, and were consequently moved to this genus. The study also revealed a number of undescribed species.

Aphantophryne minuta is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name minuta refers to the very small size of this species. Common name Myola Guinea frog has been coined for it.

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.

Austrochaperina adamantina is a species of frog in the family Microhylidae. It is endemic to New Guinea and occurs in the Torricelli and Bewani Mountains in the West Sepik Province, Papua New Guinea. The specific name adamantina is Latin for "like a diamond" and refers to Jared Diamond, credited as the collector of the holotype and "great many other valuable herpetological specimens from Papua New Guinea".

It is endemic to New Guinea and known from the northern slopes of the New Guinean Central Range in Western New Guinea (Indonesia), and from the Bewani, Torricelli, and Hunstein Mountains in Papua New Guinea. The specific name blumi honors J. Paul Blum, the herpetologist who collected the type series. Common name Kosarek land frog has been proposed for it.

Cophixalus nubicola is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from its type locality, Mount Michael in the Eastern Highlands Province.

<i>Cophixalus parkeri</i> Species of frog

Cophixalus parkeri is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea where it occurs in the central mountainous region between Chimbu and Morobe Provinces.

Common name Papua rainforest frog has been coined for it.

<i>Cophixalus shellyi</i> Species of frog

Cophixalus shellyi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and occurs in the New Guinea Highlands as well as in the Adelbert Range and on the Huon Peninsula.

It is endemic to the Philippines and is known from Mindanao, Biliran, Siargao, and Leyte; it probably occurs in some smaller, intervening islands too.

<i>Aphantophryne nana</i> Species of amphibian

Common names Camiguin cross frog, Camiguin narrow-mouthed frog, and volcano cross frog have been coined for the species.

Oreophryne notata is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from two localities, Ialibu, its type locality in the Southern Highlands Province, and Tabubil in the Western Province. It might occur more widely.
