Cophixalus riparius is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and occurs in the New Guinea Highlands in Madang, Southern Highlands, and Western Highlands provinces southeastward to the Morobe Province. [1] [3] The specific name riparius refers to the creek-side habitat from which many specimens in the type series were collected. [2] Common name Wilhelm rainforest frog has been coined for this species. [3]

Names

It is known as gwnm in the Kalam language of Papua New Guinea, a name that is also applied to Xenorhina rostrata . [4]

Description

Adult males grow to at least 45 mm (1.8 in) and adult females to 49 mm (1.9 in) in snout–vent length; males appear to reach maturity by they are 41 mm (1.6 in). The snout is short and bluntly rounded. The tympanum is only barely visible at its lower edge. The supratympanic fold is weak. The fingers and toes bear well-developed discs. Preserved specimens are dorsally purplish brown, with an irregular pattern of dark markings. These markings may sometimes form rugged dorsolateral lines or join to form a network, but only rarely reducing the lighter background to isolated spots. [2]

Habitat and conservation

Cophixalus riparius is found in montane rainforests among boulders and grass near streams at elevations of 1,900–2,800 m (6,200–9,200 ft) above sea level. Development is direct (i.e., there is no free-living larval stage). [1]

This species is common and adaptable, probably able to withstand a degree of habitat degradation. It is not facing significant threats. It might be present in the Mount Kaindi Wildlife Management Area. [1]

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 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.

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.

Choerophryne darlingtoni is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and found in the New Guinea Highlands. The specific name darlingtoni honors P. Jackson Darlington Jr., an American evolutionary biologist and zoogeographer. Common name Darlington's rainforest frog has been coined for it.

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.
