The Bulmer-nude back flying fox ( Aproteles bulmerae ), also known as Bulmers fruit bats called, is a rare bat , the on Guinea occurs. The kind forms the monotypical genus Aproteles .

The fruit bat was originally known from 12,000 to 9,000 year old fossils from the mountainous regions of New Guinea. In 1975 it turned out that the remains correspond to a species of which one specimen had recently been killed in a cave. However, no further specimens could be discovered in the following years. It was not until 1992 and in later years that colonies of the species were observed again in the assumed distribution area. All finds come from caves that were 1400 to 2400 meters above sea level. The mountains are covered by evergreen forests and, at higher altitudes, by alpine meadows.

The size information comes from a female who was measured in the 1970s. It had a head-torso length of 242 mm, a tail length of 32 mm, a forearm length of 160 mm and a weight of 600 g. The fur was dark brown on the head and brown on the underside. The wings formed from flight skins meet on the back, which thus appears naked. The membranes are light brown on the top and almost white on the underside.

On the basis of these characteristics, it was assumed that the Bulmer blackback bat together with the species of the genus Dobsonia forms the taxon blackback bat . This assumption was confirmed in a phylogenetic study in 2002 .

Almost nothing is known about the way of life of the species. One specimen has been seen eating figs . Furthermore, an adult female is known to carry a newborn male.

The flying fox is hunted as a food source by the people of New Guinea. In addition, the mountains are prone to forest and bush fires. The IUCN suggested that the total stock contains less than 250 specimens capable of reproduction and lists the Bulmer-nude back bat due to the threats as "critically endangered" ( Critically Endangered ).
