Age of rock Late Eocene-Early Oligocene
Mountain type Mountain range

The Bewani Mountains form a mountain range in northwestern Papua New Guinea. Together with the Torricelli Mountains and Prince Alexander Mountains it forms the North Coastal Range of Papua New Guinea. [1] The highest point of the mountains is at 1,960 m.

Contents

The Bewani languages and various other Papuan languages are spoken in the region.

Geology

The Bewani-Torricelli-Prince Alexander Mountains, are presumed to have been formed as an island arc in the Late Eocene-Early Oligocene. [2]

Ecology

As with other mountain ranges in Papua New Guinea, the Bewani Mountains are home to many rare species of fauna and flora and is highly biodiverse. The black sicklebill (Epimachus fastuosus) is a threatened species which is known from a few localities in the Bewani and Torricelli mountains. [1] Fiwo, a subspecies of the tenkile (Dendrolagus scottae) tree-kangaroo, is thought to be endemic to the Bewani Mountains. [3] Two frog species described in 2000/2001, Cophixalus bewaniensis and Choerophryne longirostris , are so far only known from the Bewani Mountains. [4] [5]

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 valkuriarum is a species of frog in the family Microhylidae. It is endemic to the eastern New Guinea in Papua New Guinea and is known from near Wau in the Ekuti Dividing Range south to Myola in the Owen Stanley Range. The nominal species might consist of more than one distinct species.

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.

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 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".

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.

Austrochaperina blumi is a species of frog in the family Microhylidae. 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.

Choerophryne longirostris is a species of frog in the family Microhylidae. It is endemic to Mount Menawa in the Bewani Mountains of Papua New Guinea. It inhabits the interior and edges of closed-canopy rainforest.

Some records are from close to the Indonesian border, and it is probable that this species is to be found also in Western New Guinea.

Cophixalus balbus is a species of frogs in the family Microhylidae. Molecular data suggest that it might belong to the genus Oreophryne.
