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 (Fergusson, Goodenough, and Normanby islands). [2] The specific name waliesa is derived from the Dobu word waliesa that means "namesake", in honor of Fred Malesa from Fergusson Island. He had greatly assisted the describers of this species during their expedition in the Milne Bay Province. [3]

Description

Adult males grow to 77 mm (3.0 in) and adult females to 81 mm (3.2 in) in snout–vent length. The snout is acutely pointed in dorsal view and but truncated with the lower half recessed when viewed laterally. The tympanum is distinct. The fingers have no webbing but have flattened and expanded tips. The toes are almost completely webbed and have pointed tips bearing discs. The dorsum and legs are densely covered by conical asperities. There is a thick dorso-lateral ridge running from the eye backward. The dorsum is olive green and is freckled with darker olive flecks. The sides have dark flecks that contrast with the yellow background; the yellow color gets more dominating the lower down. The chin and throat are white some high-contrast mottling or clouding of melanin, except for the vocal sac in males that is heavily stippled with melanin. [3]

A tadpole at Gosner stage 34 measures 44 mm (1.7 in) in total length. [3]

The male advertisement call consists of 3–8 somewhat "raspy" nasal notes, emitted at a mean rate of about four notes per second. [3]

Habitat and conservation

Papurana waliesa is an uncommon species associated with slow- and faster-flowing streams, ditches, and Pandanus swamps, in disturbed grassy habitats and villages. It is found up to 600 m (2,000 ft) above sea level. [1]

Papurana waliesa can adapt to certain anthropogenic habitats, but it has a small range and is found in low numbers. Moreover, it is restricted to elevations that are under moderate to heavy human disturbance. [1]

Papurana daemeli is a species of "true frog", family Ranidae. It is found in New Guinea, northern Australia, and some smaller islands. It is the only ranid frog found in Australia. In Australia, the species is restricted to the rainforest of northern Queensland and the eastern border of Arnhem Land, in the Northern Territory. In Australia, it is usually known as wood frog or sometimes as water frog. Other vernacular names are Australian wood frog, Australian bullfrog, and Arnhem rana.

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 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.

Asterophrys leucopus is a species of frog in the family Microhylidae. It is endemic to northwestern Papua New Guinea where it is known from three locations: Stolle Mountain in the Sandaun Province—its type locality, and Hunstein Mountains in the East Sepik Province and the Bewani Mountains in the West Sepik Province.

Austrochaperina basipalmata is a species of frog in the family Microhylidae. It is endemic to the mountain ranges of northern New Guinea and is found between Tawarin River in Papua, Western New Guinea (Indonesia) and Torricelli Mountains in Papua New Guinea.

<i>Callulops robustus</i> Species of amphibian

Callulops robustus is a species of frog in the family Microhylidae. It has traditionally been considered as wide-ranging species found in both Western New Guinea (Indonesia) and Papua New Guinea. However, it is likely that specimens from the type locality, Misima Island, and New Guinea represent different species. If so, name Callulops robustus belongs to the Misima Island species, and the mainland species is unnamed. Other island populations may or may not belong to Callulops robustus. Callulops microtis from the mainland has already been removed from synonymy with Callulops robustus.
