The genus of the large New Guinea nasal purse ( Peroryctes ) belongs to the New Guinea nasal purse (Peroryctinae) and comprises two species that, as the name suggests, live in New Guinea .

With a head-torso length of up to 56 centimeters and a weight of up to five kilograms, these animals are the largest nasal sacs. Their fur is long and relatively soft. Like all nasal aspirators, they have an elongated snout, relatively small ears, and a long but inadequate tail. The long hind legs of this genus are a sign that they can run fast or even hobble.

These animals live in rainforests up to an altitude of 4000 meters. They live on the forest floor and are nocturnal loners. To sleep, they build nests out of twigs or grass on the ground. They are omnivores that feed on insects and small vertebrates, but also on fruits.

One to six young animals are born after around 15 days of gestation. They are weaned at around 60 days, after which they remain near the mother for a short time before they start their solitary life. Life expectancy is estimated at 2.5 to 3.5 years.

The genus of the Great New Guinea Noseband is divided into two types:

  • Raffray New Guinea- Noseband ( Peroryctes raffrayana ) inhabits all of New Guinea and smaller offshore islands. Its fur is dark brown on top, sometimes with black patterns. The underside is lighter, yellow or light brown. The species reaches a head body length of 27.5 to 39 centimeters, a tail length of 13.2 to 18 centimeters and a weight of 650 to 1100 grams. Their habitat are forests from 500 to 4000 meters high.
  • Giant New Guinea nose bag ( Peroryctes broadbenti ) is also dark brown in color on the upper side, but the flanks are reddish and the belly white. The species reaches a head body length of 34 to 56 centimeters, a tail length of 9.5 to 23 centimeters and a weight of up to 4.9 kilograms. He lives in southeastern New Guinea.

Habitat degradation and hunting for their meat are among the main threats to New Guinea noseppers. While Peroryctes raffrayana occurs more frequently and by the IUCN 'not at risk' ( least concern ) is classified applies Peroryctes broadbenti considered rare and is considered "high risk" ( endangered classified).
