Oreophryne brunnea is a species of amphibian in the family -mouthed (Microhylidae) to Papua New Guinea .

features

The species reaches a head-trunk length of 16 to 19 millimeters. The top of the body appears in various shades of brown, from pale reddish brown to dark brown. The ventral side is colored similarly. The head is broad and the canthus rostralis is clearly visible. The rein region is somewhat deepened. The eardrum is clearly visible, but much smaller than the eye, which is large relative to other species. The first finger is shorter than the second, the third finger is the longest. There are no webs between the fingers. The fingers' adhesive discs are very large, wider than they are long, and much larger than those of the toes. The toes are connected by webbed feet, but they don't reach far between the toes.

Occurrence

Oreophryne brunnea occurs in the southeast of Papua New Guinea in the higher elevations of Cape Nelson in the Oro Province and the neighboring Mount Suckling massif in the Milne Bay Province . The species inhabits the altitude range between 820 and 1000 meters above sea level on Mount Trafalgar on Cape Nelson and can be found at heights of 900 to 1430 meters on the saddle between Mount Suckling and Mount Dayman .

Danger

Oreophryne brunnea is not classified as endangered by the first descriptor. Several factors contribute to this assessment: Their area of ​​distribution is difficult to access. The rainforests in which the species lives are far removed from human civilization and not yet influenced by agriculture and tropical logging. The mostly steep slopes of Mount Trafalgar and Mount Victory, which protect the population, also contribute to this. Nevertheless, climate change can contribute to rapidly changing ecological conditions and disrupting the habitat .
