Choerophryne nigrescens | |
Choerophryne nigrescens is a species of frogs in the family Microhylidae. [1] [2] It is endemic to the Papua Province, Indonesia, and is known from its type locality and two other localities on the island of Yapen (Papua Province), off the north-western coast of New Guinea, as well as from one record from Foja Mountains in New Guinea. Common name blackish choerophryne has been suggested for it. [1]
Three adult males in the type series measure 17–18 mm (0.67–0.71 in) in snout–urostyle length, making it a relatively large Choerophryne; females are unknown. The snout is moderately long (20–21% of the body length). The eyes are moderately-sized. The tympanum is small. All fingers and toes bear large and conspicuous discs. The dorsum is reddish brown, with blackish blotches. There are also blackish bands in the limbs. There are small whitish spots allover. The ventrum is white with dense, blackish reticulations. [1]
The male advertisement call is a series of distinctly pulsed notes, but in tight succession so as to give an impression of a single, modulated note. The dominant frequency is at 2.9 kHz. [1]
At Yapen, Choerophryne nigrescens inhabits primary and secondary rain forest at elevations of 5–850 m (16–2,789 ft) above sea level. At sites where Choerophryne nigrescens co-occurs with Choerophryne arndtorum , it is much less abundant than the latter species. Males call from hollows and crevices of large, rotting logs on the ground, sometimes higher from the ground (to 2.5 m) on plant stems. One specimen was found on top of a pile of logs. [1]
Choerophryne exclamitans is a species of frogs in the family Microhylidae. It is endemic to Papua New Guinea and only known from two locations on the slopes of Mount Shungol in the Morobe Province. It might be more widely distributed.
Choerophryne fafniri is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the north-western slopes of Mount Giluwe and south-east of Mount Hagen in the Southern Highlands Province.
Choerophryne gudrunae is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from its type locality near Kowat in the Adelbert Range, Madang Province.
Choerophryne gunnari is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from the area of its type locality in the Central Province, and from the western slopes of Mount Obree, also in the Central Province.
Choerophryne laurini is a species of frogs in the family Microhylidae. It is endemic to Western New Guinea and known from the Wondiwoi Mountains, at the base of the Wandammen Peninsula. Common name Wandammen albericus frog has been suggested for it.
Choerophryne rhenaurum is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from its type locality, Moiyokabip in the upper Ok Tedi catchment in the Western Province.
Choerophryne sanguinopicta is a species of frogs in the family Microhylidae. It is endemic to southeastern Papua New Guinea and only known from the vicinity of its type locality, the northern slope of Mt. Simpson in the Owen Stanley Range, Milne Bay Province, although it is expected to occur more widely. The specific name sanguinopictus, from Latin for sanguis ("blood") and pictus ("painted") refers to the distinctive red blotching and punctations characteristic for this species.
Choerophryne siegfriedi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from its type locality, Mount Elimbari in the Simbu Province.
Choerophryne swanhildae is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from the Hagen and Kubor ranges.
Choerophryne variegata is a species of frog in the family Microhylidae. It is endemic to West Papua, Indonesia, and is only known with certainty from its type locality, Digul River. It is assumed that most records from elsewhere refer to other, possibly undescribed species. As the species is only known from one specimen from its vaguely stated type locality, its ecology is essentially unknown, although it is presumed to be a rainforest inhabitant. No other specimen has been collected anywhere near the type locality. Despite all this, vernacular name common rainforest frog has been coined for it.
Choerophryne allisoni is a tiny species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from its type locality, Mount Sisa in the Southern Highlands Province. The specific name allisoni honours Allen Allison, an American herpetologist. Common name Allison's mountain frog has been coined for this species.
Cophixalus balbus is a species of frogs in the family Microhylidae. Molecular data suggest that it might belong to the genus Oreophryne. It is known from the vicinity of its type locality in Yapen island, Papua Province, Indonesia, as well as from the Hunstein Mountains and Bewani and Torricelli Mountains in Papua New Guinea.
Cophixalus tetzlaffi is a species of frogs in the family Microhylidae. It is endemic to West Papua, Indonesia, where it is only known from near its type locality, Fakfak Mountains near the town of Fakfak.
Copiula pipiens is a species of frog in the family Microhylidae. It is known from its type locality, Wirui near Wewak in the north coast of New Guinea, Papua New Guinea, and from the island of Yapen, off the north-western coast of New Guinea, in the West Papua province of Indonesia. The Yapen population might represent a different but closely related species. Common name Wirui Mehely frog has been coined for this species.
Oreophryne wapoga is a species of frog in the family Microhylidae. It is endemic to Western New Guinea (Indonesia) and is known from its type locality, the headwaters of the Wapoga River, and from the island of Papua (province), both in the Papua province. The Yapen population might represent a separate species.
Litoria humboldtorum is a species of frog in the subfamily Pelodryadinae of the family Hylidae. It is endemic to the Papua Province of Indonesia, and found on Yapen Island as well as on the foothills of the Foja Mountains in the mainland New Guinea. The specific name refers to Alexander von Humboldt, Wilhelm von Humboldt, Humboldt University of Berlin, and its Museum für Naturkunde.
Choerophryne amomani is a species of frogs in the family Microhylidae. It is endemic to the island of Yapen, off the north-western coast of New Guinea, and administratively a part of the Papua Province, Indonesia. The species is only known from the Amoman Mountain, its type locality, after which it is also named. Common name Amoman choerophryne has been suggested for it.
Choerophryne arndtorum is a species of frogs in the family Microhylidae. It is endemic to the island of Yapen, off the north-western coast of New Guinea and belonging to the Papua Province, Indonesia. It is known from the Waira Mountain, its type locality near Serai, and from another locality further east. Common name Arndt's choerophryne has been suggested for it. The specific name is plural genitive and honours Dr. Rudolf G. Arendt and his family.
Choerophryne microps is a species of frogs in the family Microhylidae. It is endemic to Western New Guinea and known from the Wondiwoi Mountains, at the base of the Wandammen Peninsula. The common name "small-eyed choerophryne" has been suggested for it.
